#

can OpenCV run on a RP3B+ ?

#

or is it overloaded

Hi guys, Couldn't find anything solid regards with the kind of solution I am after online, so had to post this here. Please note I can't build a desktop which is definitely much better for such work. I mainly work on OpenCV. Currently doing good with python. C++ is an option. ...

I am using adafruit io

#

my problem is that my esp8266 does not receive any data

#

my sketch

#

📎 adaio.ino

#

@royal rapids

#

It connects sucessfully

royal rapids Oct 28, 2020, 2:30 PM

#

Ok

#

what do your feeds look like?

sacred depot Oct 28, 2020, 2:30 PM

#

it has a value

#

📎 unknown.png

#

like this

#

Adafruit_MQTT_Subscribe *subscription;
  while ((subscription = mqtt.readSubscription(5000))) {
    if (subscription == &onoffbutton) {
      Serial.print(F("Got: "));
      Serial.println((char *)onoffbutton.lastread);
    }
  }

#

if i add data it does not receive it

#

@royal rapids here

royal rapids Oct 28, 2020, 2:38 PM

#

Looking..

#

@sacred depot what happens when you add a value called "ON" to the feed?

#

does it your board receive it?

sacred depot Oct 28, 2020, 2:40 PM

#

no

#

that 's the problem

royal rapids Oct 28, 2020, 2:41 PM

#

@sacred depot Ok. Could you paste your code as a gist here, https://gist.github.com/, and share it in the channel? Make sure to remove your WiFi credential and AIO keys

@sacred depot your Serial Monitor printed out "MQTT Connected"?

sacred depot Oct 28, 2020, 3:07 PM

#

yep

royal rapids Oct 28, 2020, 3:07 PM

@sacred depot Could you reset the board, keep the monitor page open, and see if the board shows up under Connections when it prints that?

sacred depot Oct 28, 2020, 3:08 PM

okay wait a sec

hi. does anyone know the max mqtt keepalive setting that is allowed on the mqtt broker on adafruit io?

#

with a cellullar conneciton I would like this to be as long as possible

sacred depot Oct 30, 2020, 5:12 PM

#

Should one be able to see the io dashboards on ios?

low depot Oct 30, 2020, 6:26 PM

#

with a cellullar conneciton I would like this to be as long as possible
Seems to be pretty short. <5 minutes? If that is correct it is not very well suited for ultra low power sensor applications 😦

#

Aws iot has 20 minutes. Had hoped adafruit was longer than that

royal rapids Oct 30, 2020, 6:34 PM

#

@low depot It should be configurable from your MQTT client, not the broker.

low depot Oct 30, 2020, 6:52 PM

#

Yes but the broker ultimately decides what the maximum allowed timeout is right? It seems like the socket is closed when i use keepalive longer than approx 5 minutes. Same setup have worked towards aws iot with 20 min keepalive.

#

If anyone can confirm they have worked with longer keepalive timeouts it is great. (then the problem probably is on my end)

royal rapids Oct 30, 2020, 7:42 PM

#

5 minutes is our standard keepalive. 20 minutes is a long time to keep a connection open.

Not saying the branch is not correct. just that it may not fix my issue. 🙂

@acoustic igloo That is good. I'm using that branch to test a dev build of Adafruit IO Wippersnapper which has tight timing constraints and it doesnt drop packets

acoustic igloo Oct 30, 2020, 8:28 PM

#

hmm I am using a feather M0 not sure if that matters

#

I am also going to set up a test harness that can publish messages to the feed so I dont need to double the messages (the dashboard push button wants to post on press and release) This should give me a way to test a bit better.

@acoustic igloo that'd be great. Let me know how it goes

acoustic igloo Oct 30, 2020, 8:32 PM

Hi!
I have attached a D1 mini - ESP8266 to a led strep and I try to adjust the leds via my google home. I have succeeded to do so with IFTT and adafruit.io. I am using the adafruit package and mqtt protocol to send messages. This works fine up to 3 or 4 hours, but then the D1 gets stuck in some kind of zombie mode, and does not read the incoming messages anymore. Does anyone know why the D1 is freezing and how I can solve this problem?

acoustic igloo Oct 30, 2020, 10:28 PM

@royal rapids I set up a test script you can see it here: https://github.com/cbitter78/iot-beer-machine/blob/adafruit/test_harnis/test_vend.py. Then I double checked the pr and I was testing from https://github.com/Fapiko/Adafruit_MQTT_Library but I was on the wrong branch. 🤦‍♂️ Good news is, so far no misformed packets!

I am noticing that if I post a message the the feed the feather gets it very quickly.. LOVE IT. However my project is to convert a 1980's vending machine (cans) to my IOT beer cooler As such the feather gets a command, that has the slot number to vend. vending (turn on a motor, wait until its done, turn it off) takes about 10 seconds. During this time if I post new messages to the feed the feather for a second vend when its done, The feather gets the message but never calls my call back function. Would love your thoughts. [I fully expect this to be my codes fault 😉 ]. I can test over and over again because I built a test rig that simulates vending with some motors.

@royal rapids This fixed my issue https://github.com/cbitter78/iot-beer-machine/pull/1/commits/1e397933abc029259031e5d20ef2a4ab6899efcb#diff-0c8b26aa178a448635c3c311e20d35f954d71dcc34ee982353a5c6b66e1ffeb6L133. You could say it was my code. I switched from using mqtt.processPackets to mqtt.readSubscription. Not sure what that suggests but hey everything is working awesome. NO DROPPED Packets when using the branch from https://github.com/adafruit/Adafruit_MQTT_Library/pull/170. its 1000% better! Thanks again for the help.

I suggest getting the Nano 33 wifi working then just use Adafruit_MQTT_Client and pass it the wifi client. You can see this pattern here https://github.com/cbitter78/iot-beer-machine/blob/adafruit/iot-beer-machine/iot-beer-machine.ino#L39. (not the same board, but the same idea)

Has anyone got Adafruit IO working with Unity? 🙂

I need some guidance on Adafruit IO. I have I Pi 4 and I recently bought the 7" Raspberry Pi touchscreen and a case to hold it all as a kiosk style indoor air quality display. I have dashboard and feeds allset up in IO. Functionally, everything is fine. Is there a way to display just the gauges? In effect crop out top, right side, bottom of IO Dashboard web page to just show the gauges? The top image is as it shows via VNC, bottom is what I desire it to look like. Of note is that at bottom of page is a bunch of links, other stuff that I also want to hide.

I think there is an argument to launch chromium in fullscreen mode (aka kiosk mode)

#

@south gust --kiosk or --app , I don't know the real difference.

south gust Nov 3, 2020, 5:50 PM

#

I thought about that but while not 100% sure I think I'll still get what amounts to the Adafruit header and footer since those items are part of page.

south gust Nov 3, 2020, 7:36 PM

#

@late pelican You were right. I had been looking at a different site regarding kiosk mode on a Pi but on Adafruit IO page there is an option to share in kiosk mode which strips out everything except the blocks added to dashboard.

Hi @royal rapids I had an idea and I'm curious to get your take on it. I think it would be helpful if Adafruit IO+ had a feed generated automatically that kept a tally of operations per minute for a given account. For example, if I get throttled at 60 operations per minute and I'm currently doing a number of feed updates that total 34 in the last minute, the auto-generated feed would show 34. This would be really helpful on devices to allow some devices to use more IO feed updates when there's some available.

@sacred depot hi. like a counter?

#

There is an error topic

sacred depot Nov 5, 2020, 4:02 PM

#

hi @royal rapids yes, I was playing with this yesterday and the simplest may be to expose the feed updates/min that IO uses for throttling. If I can read that value I can have my code throttle up/down based on my cap

Is the IO server code on github somewhere? I found this repo but it hasn't had commits anytime recently, I'm thinking it may be an older version or something? https://github.com/adafruit/adafruit-io-node

Ah, I see a relavent answer here: https://github.com/adafruit/io-api/issues/1#issuecomment-361990411

GitHub

Is IO itself Open Source? · Issue #1 · adafruit/io-api

Is the code for adafruit.io itself Open Source, i.e., could I run my own instance of IO including the Web interface?

#

I wonder if there is any interest in adding some sort of "blueprint" importing and exporting feature to the IO server. I noticed walking through the set up in this guide: https://learn.adafruit.com/aio-quote-board-matrix-display/code-the-quote-board#adafruit-io-group-feeds-dashboard-3071451-9 that there are quite a few things that need to get set up by the user (Feeds, Groups, Dashboards). Perhaps the server could generate some JSON blob that describes all of those various items that need to be set up. The blob could be provided alongside projects. The server could then have an import function where the JSON blob can be pasted and it will parse through and create anything that the user doesn't already have set up.

I've got a Huzzah32 talking nicely to Adafruit.io using the examples provided in the Arduino Adafruit IO library. When I send a string feed->save(myString) with escaped double quotes, the send fails. If I convert double quotes to single quotes, the data is published: myString.replace("\"","'");feed->save(myString). Is this working as intended? Am I making an obvious mistake? The replacement is easy enough to implement, but seems to present a problem if the string being published is something like JSON, which is supposed to have the double quotes.

Hey guys, I have a raspberry pi project where I'm using the following python libraries: adafruit_mcp3xxx.mcp3008 and adafruit_mcp3xxx.analog_in
I'm trying to read temperature values from an MCP9700A, which is a "Low-Power Linear Active Thermistor IC".

I'm getting odd temperature readings when I follow the formula given in the documentation for the device - which I get by doing:

temp = (chan.voltage - 0.5)*100

More specifically, they seem to be about 20C above expected. So subtracting 0.7 seems to fix it but I'm doubtful if the readings are actually accurate. I'm wondering what chan.value does incase I can maybe find out if I can work out the temperature using that instead!

now to learn about input pullup vs input, i have no idea 😄

left dragon Nov 8, 2020, 11:56 PM

#

basic idea is that a digital input cannot be left "floating" it needs to be HIGH or LOW

#

the INPUT_PULLUP uses an internal resistor to keep the pin HIGH until you press the switch, then it goes LOW

#

you could use an external 10K to pull the pin HIGH and use INPUT, but since it's built in...

#

i've found instructables to vary in quality from excellent to "HUH???"

Looking for some assistance on connecting a Grove sensor to Adafruit.io. My research so far is taking me down the road of learning more on push requests and scripting them in python. The goal of the project is to use sensors to push data into adafruit.io since Seeed discontinued their IFTTT connector a few years back. This all may be a crappy explanation but I'm trying to breath new life into a bunch of sensors. I can send a curl command (guessing thats the right term) via command prompt to get LEDs to go on which is pretty cool (as an example).

#

Really want to hook in the sensors (temp/hum/dust) to an adafruit.io dashboard. Just not sure how to integrate any of this. Im in the understanding that this Grove sensor kit can utilize REST API (barely familiar here)

graceful sluice Nov 10, 2020, 7:16 PM

#

sensors don't usually do comms on their own. they usually need to be connected to a controller. what controller are you using?

marsh violet Nov 10, 2020, 7:24 PM

#

Its using the Grove board which is connected to the internet via wifi

#

I can launch the app on my phone to connect to it and it even has API strings to use. Just trying to figure out how to run a script that will allow the grove sensor board to talk to adafruit.io

#

📎 image0.jpg

#

@graceful sluice This used to hook right into IFTTT which did all the work of communicating

#

Here is a request line that came from the Wio Link app

📎 image0.png

marsh violet Nov 10, 2020, 7:56 PM

#

if I copy/paste that curl example into a Windows command line it works like a charm. Just trying to figure out what can I do so that I'm getting constant readings and data sent to Adafruit.io

#

what all is involved in standing that up via a rest api

#

is there an easy button for this one where I can just copy/paste that curl example into an app or do I need to start from scratch and host a python script on AWS? I know the concepts here and lack full knowledge on how to take this project across the finish line (willing to learn though!)

graceful sluice Nov 10, 2020, 8:10 PM

#

if the wiolink board can be reprogrammed to send its data to AIO, that's the best option. Otherwise, you'll have to set up some sort of scheduled job to read the data from seeed.io and post it back to AIO.

marsh violet Nov 10, 2020, 8:23 PM

#

Would I program it solely in python?

graceful sluice Nov 10, 2020, 8:32 PM

#

I don't think you can do that. Have you checked the manual for the board?

marsh violet Nov 11, 2020, 12:21 AM

So I ran the curl push example in a command line and it works which tells me I’m pulling data from the sensors. Now time to automate

New UI changes are nice! Is there a way to move keys between groups with their data? The UI doesn't seem to have a way to do it, and I tried to insert a group name in front of an existing key (that is not in a group, aka default) via Feed Info dialog, but that doesn't work.

marsh violet Nov 11, 2020, 2:13 PM

@graceful sluice here is the visio of my understanding on how this board works. Just trying to figure out the what/how of a REST API orrr if there is something out there that lets me get the GET/POST requests into an app and then map it to Adafruit.

I have a device streaming sensor data to Adafruit IO. It crashes once every 24hr, no specific time, but it always happens when I send data to a particular feed. The only difference between this feed and the rest is that it is uploading a string value (Ex: 'a', 'b', 'c'...) while the rest are integers/floats. I'm using the python API, and here is the line which fails:python aio.send_data(string_feed.key, my_string_value, metadata) and here is the error I get: bash ERROR:root:Could not send data to Adafruit IO. Exiting System This error message is from the logs I am generating from my device so that I can troubleshoot (using the python3 logging package). How can I get error message feedback from send_data()?

Getting a "Failed to request Hostname" message when trying to send data to my feed. It had been happily plugging away for days before failing around 2am this morning. Any ideas? resetting my pyportal seems to have cleared it up but this device is monitoring the air temp in the room that the water pipe comes into my house (it froze last year) and sends me an alert when it gets below 32 and I'm hoping to avoid having it fail when I need it.

late pelican Nov 17, 2020, 12:12 PM

maybe you can add the faulty code in a try: except: block so it doesn't crash if your Internet connexion is down, for example ?

white apex Nov 17, 2020, 12:41 PM

It has one, the except is catching it and telling me the message about Failed to request hostname and then looping again

#

Do I need to do some kind of reinitializing of the connection to adafruit io if this happens?

I do the connection to the feed once before entering the while loop, so that would make sense to do if this is something that indicates that connection is broken somehow

io.run is killing my stepper motor:

void loop() {

  //Serial.print(throttleCount);
  if (currentThrottleCount >= throttleReset) {
    io.run();
    currentThrottleCount = 0;
    Serial.print("reset");
  }
  currentThrottleCount++;

  if (stepper.distanceToGo() != 0) {
    stepper.run();
  }
  else
    stepperOff();
}

#

i tried to throttle it, but its still not ideal

#

without the throttle, my stepper motor runs 100x as slow, so io.run() is really slowing down the loop

hey, this is a less frequented channel but people to stop in

#

let me see if I can help

#

Are you reading or writing to IO for your stepper motor @twilit jasper ?

#

If you are reading a value to action on with the stepper, I'd read the value (like number of steps) then interate through using a local variable so your IO stuff is not slowing your stepper motor.

#

you may also want to ask in #help-with-projects to get some other stepper ideas

twilit jasper Nov 18, 2020, 12:50 AM

#

@sacred depot i use io to trigger my stepper to move between home and a predesignated position

#

so i guess its listening for events

#

the stepper motor part works fine, but the io.run() makes the stepper.run() perform much slower than normal

#

i dont know what a good solution is

sacred depot Nov 18, 2020, 12:54 AM

#

well IO is not going to be very fast for that, and if your motor moves too fast IO may not update in time

#

I'd suggest a routine where you read the IO to a local value, then step

twilit jasper Nov 18, 2020, 1:00 AM

#

@sacred depot isnt reading the io to a local value still going to need to run io.run() in the loop? which would result in the same delay?

I started with the example sketch "adafruitio_07_digital_out" and I have a toggle on my dashboard with the on and off text labeled 1 an 0, and it works fine. Ok so now I want to change the text to "On" and "Off" and its giving me trouble. I'm using void handlemessage(AdafruitIO_Data *data) and then I tried this IF statement if(data->value() == "On") but it always evaluates as FALSE no matter what, even when serial.print(data->value()); gives me "On" I must have some kind of data type mismatch. Can anyone tell me what I'm doing wrong?

I've noticed that upon start up, the device doesn't know the initial state of a toggle on AIO. I've been using digital->onMessage(handleMessage); and handleMessage(AdafruitIO_Data *data) but that method only works when an event on AIO (like a toggle state change) happens. So I have to hit all the toggles to get everything synched. It's there a way to read the state of a toggle on demand, that I could run at start up?

I am trying to send an IO dashboard data to a Magic Mirror I have made. I'm trying to load the dashboard link in to an iFrame on my monitor. I can do this just fine with YouTube live streams but if I swap out the YouTube address and replace it with the IO link nothing happens. The out of the box MM is set to http vs https but the YouTube vids are https and it handles them just fine. I sent same IO link to phone and it rendered no problem but I expect phone already configured for https but I may be barking up wrong tree on that being an issue. Anyone have any thoughts ideas suggestions?

tired prism Dec 9, 2020, 4:56 PM

#

@twilit jasper hey thanks for this report about your CPU usage going up, i'd like to look into that with you a bit if you're willing:

is it ANY dashboard, or just particular ones?
the feed page itself, just the list of feeds? how many feeds do you have?
if you refresh, does it go back to normal for another 30 minutes, then spikes again?

if you set one of the dashboards where you're seeing this to "public" and share the link with me (as a DM, if you like), i'll try to reproduce on my side and see if we can troubleshoot this

twilit jasper Dec 9, 2020, 5:19 PM

twilit jasper Dec 9, 2020, 6:31 PM

#

@tired prism at 12:20 I started my dashboard, the feeds list, and an individual feed in separate chrome tabs. chrome was varying around 1-3% cpu usage. by 12:25 it was between 2-5%, at 12:50 it was still around 2-5%, at 1:20 it was between 4-10%. The task with highest cpu useage in chrome was the dashboard, second was the individual feed page, 3rd was the entire feeds page. I manually ended the tasks in chrome. With the 3 tabs/tasks shutdown, chrome went down to 0%. reloading the 3 tabs/pages took the chrome cpu usage to 2-5%

#

Image from a 20 second profile in chrome of the dashboard

📎 unknown.png

#

profiling the feeds tab also showed I.onmessage as the longest blocking time, but only about 16ms

#

Now at about 1:40, im hearing my cpu fan whining and oscillating again, cpu for the 3 tabs is about 3-7%

twilit jasper Dec 9, 2020, 7:53 PM

now at 2:50pm its a steady 7-11% with just the dashboard alone

Is there a place where I can find more info on the Network Disconnected message?

#

WiFi connected, your IP address is
192.168.1.229
Connecting to Adafruit IONetwork disconnected.
Network disconnected.
Network disconnected.
Network disconnected.

#

I had a mostly working setup, but a few feeds started misbehaving so I updated the IO and MQTT libraries. That's when the Network Disconnected message started. Rolling back the libraries to the previous versions and the issue persists. Doh

nimble raptor Dec 17, 2020, 9:47 PM

#

I solved it. I had previously modified AdafruitIO_ESP32::_connect() to remove the "_disconnect()" and "WiFi.begin" lines, so I could maintain my own wifi scanner.

Future persons searching on this "Network disconnected." error message. Double check your wifi credentials in config.h. Even if you see the Wifi Connected message. Adafruit IO library is attempting to kill the existing connection and reconnect, and failing.

steel tundra Dec 18, 2020, 12:06 AM

#

Is this on a IP or Account basis? We do not currently limit the number of clients that can connect to Adafruit IO, but we do limit the rate at which connections may be attempted to 20 per minute. Exceeding the connection attempt rate limit will result in a temporary ban. from https://io.adafruit.com/api/docs/mqtt.html#mqtt-connection-details

Hi, im having a issue like a strange behavior, i have two arduinos mega + esp8266 in slave / master configuration. Both are connecting and sending data to adafruit io withou any error message, the issue begins here.. one esp8266 works fine, but the another one suffer of long time disconnected, eventually it get disconnected and reconnect it latter... during this disconnected time it become unresponsive to dasboard buttons etc.. i need it to be reliable, but im not understandt this behavior. any clue? no error messages... it disconnect for a long time like minutes, while it shouldnt. Any clue where im doing wrong? both projects are almost identical, so im not understanding this difernece in connection behavior. I apreciate any help. Ty 🙂

tired prism Dec 22, 2020, 6:36 PM

#

@steel tundra the connection limitation is a special throttle just for connecting. Once connected, it uses your regular throttling limits, but attempts to connect are specially limited this way. Reason for this is that a bad configuration can hammer us pretty hard as it loops and retries with bad credentials or whatever.

#

The throttling is all account-based

#

Let me know if this is clear!

royal rapids Dec 22, 2020, 6:55 PM

@worldly bramble Could you check io.adafruit.com/monitor and see if they get assigned the same identifier?

royal rapids Dec 22, 2020, 7:28 PM

#

@worldly bramble Could be a number of things! IOT is tricky in that way.

#

Could you try only sending data from the ESP which gets disconnected and see if it still gets disconnected?

#

You can send the expected values on a feed from the Adafruit IO web interface instead of from the master/main node you're using.

Sorry @violet coyote I’m not an Android os developer and that’s a bit beyond the scope of the help with Adafruit IO channel. I suggest you start with the very first step of getting a basic app going. https://developer.android.com/training/basics/firstapp

#

Then add 1 new thing to it like a button.

#

Then hook that button up to something. Basically break your problem down into small pieces.

And learn each step as you go.

Is there a framework for working with a pitft and displaying static text etc?

if you're just displaying static text then i doubt you'd need that. Maybe you need to find some other example.

I've been doing some tests, and it seems that the problem only appears when I turn on the second esp8266. From the moment I turn on the second device, the first one starts to lose connection and takes 1 to 15 minutes without connecting. My current usage on the monitor never exceeded 20 per minute. Any idea? I don't know if both are registering with the same id. I did not post the code, because any code I put gives the problem, so it is related to the fact that two devices are connecting and not in the code itself. Any clue? i can post some code used by me if you think it helps. https://forums.adafruit.com/viewtopic.php?f=56&t=173234&p=845578#p845578

Hello.. How can i set i client name or id to make brokker diferentiate two devices? like AdafruitIO_WiFi io(IO_USERNAME, IO_KEY, WIFI_SSID, WIFI_PASS); Where i set the AIO_CLIENT?

graceful sluice Dec 28, 2020, 3:35 PM

#

I don't immediately see a way to do that, but why would the broker need to differentiate between devices anyway?

royal rapids Dec 28, 2020, 4:06 PM

#

@worldly bramble The client ID is set in Adafruit IO Arduino automatically. depending on which device you're using, it either uses the MCU's silicon ID or the MAC address for the network adapter

#

@graceful sluice two identical CIDs (client identifiers) would cause Adafruit IO to reject the second client's attempt at connecting to IO.

#

some MQTT brokers handle this behavior differently, but that's how it's handled within IO

Hey guys, As I am new here, feel free to point me to a better place to ask this. I am trying to steer 2 TFT 1.8 inch displays from my Raspberry pi zero WiFi and getting weird issues. I am using the adafruit RGB display lib: https://github.com/adafruit/Adafruit_CircuitPython_RGB_Display

I modified the example that shows an animated gif so that I take 2 display objects created like this:

DISPLAY_1 = st7735.ST7735R(
    spi,
    rotation=90,
    cs=cs_pin_1,
    dc=dc_pin,
    rst=reset_pin,
    baudrate=BAUDRATE,
)```
The difference between the displays is only the `cs_pin`. One display is connected to `CE0`, the other to `CE1`. All the other wiring is identical (do I have to have a different dc pin?)  I then load both gifs into buffers of their frames and show them in the loop:
```python
start_time_1 = 0
start_time_2 = 0
while True:
    if start_time_1 + frames_gif_1[frame_index_1].duration < time.monotonic():
        start_time_1 = time.monotonic()
        frame_index_1 = (frame_index_1 + 1) % len(frames_gif_1)
        self.displays[0].image(frames_gif_1[frame_index_1].image)
    if start_time_2 + frames_gif_2[frame_index_2].duration < time.monotonic():
        start_time_2 = time.monotonic()
        frame_index_2 = (frame_index_2 + 1) % len(frames_gif_2)
        self.displays[1].image(frames_gif_2[frame_index_2].image)
    time.sleep(0.001)

The issue is that one display shows the gif as expected, while the other one triggers for setting an image to either of displays, resulting in image flickering between two gifs. It seems that the CE0 pin always received the data, while the CE1 correctly received data only when addressed. Any pointers are much appreciated.

This function sends my sensor data to the Bluefruit LE connect and, then, my Rx feed correctly: uart_server.write("{},\n".format(kPa, )); where kPa is pressure in kilopascals. But does anyone how to read data sent from the output feed to the Bluefruit app? I guessed uart_server.read() and, though it doesn't cause an error, it only prints " b' ' "'s.

Running into a brick wall trying to send an image from an ESP32 + OV2640 camera to Adafruit IO. I successfully get the image data from the camera & convert it into base64 encoded data, which I can print on the serial console then copy/paste into a converter to retrieve the image. However whenever I try to save() that data to Adafruit IO it causes a LoadProhibited exception on address 0xc000e247, which I believe is a 'garbage' address as it is out of the acceptable range? If you look at this code, I can print the String on line 76 just fine, but trying to save() it on line 78 always fails.

Does anybody know how the feed naming convention for the Dark Sky weather integration translates to the Arduino library? The documentation gives the syntax for MQTT connections as :username/integration/weather/:id/:type but I cannot find anything that tells me what part of that, or what format, to give the AdafruitIO_Feed object.

#

Regular user-created feeds are given in the form :username/feeds/:group.:topic for MQTT connections & the Arduino library just takes the group & topic parts like io.feed(":group.:topic"), so I wonder whether the library even supports feeds under the 'integration' path, if it (appears to) assume that all feeds are part of the 'feeds' path?

dim sphinx Jan 19, 2021, 6:22 PM

#

Did some digging, it appears the library simply doesn't support it, because it always builds feed URLs with :username/feeds/

⚠️ We are scheduling a maintenance window on January 20th (TODAY) starting at 11am ET. We are hoping to limit the downtime to under 2 hours.

I believe this is our first scheduled maintenance since the launch of Adafruit IO.

If you are connecting via mqtt, we are anticipating that your data will still arrive, but will not process until the maintenance is completed (this is dependent on the length of the downtime, and is not guaranteed in any way). New connnections to mqtt during this window may be rejected until the maintenance is completed. The API and web front-end will be taken down entirely during this time.

After that outage I had to power cycle all of my ESP8266 nodes which deep sleep between sensor readings before they would start publishing again. Can anybody think why? When they reset after a deep sleep they loop while io.status() < AIO_CONNECTED so I would've thought they would just sit in that loop until the service came back?

Interestingly some other ESP8266 I have that never deep sleep didn't require power cycling - the difference being that they were presumably running their loop() functions with io.run() at the top, while the deep sleeping nodes were looping waiting for the connection status & never reached io.run() further down.

royal rapids Jan 20, 2021, 6:55 PM

@dim sphinx Which libraries are you running on the ESP's using deep sleep?

dim sphinx Jan 20, 2021, 7:07 PM

@royal rapids It's a very basic sketch, it just uses the Adafruit SHTC3 library. The config.h is just the standard Adafruit IO boilerplate example (which includes AdafruitIO_WiFi) with my SSID/pw/IO key substituted.

https://gist.github.com/CJ-Davies/6518c691382e8133969599ca61cf417d

I'm guessing maybe something happens with the io.connect() call on line 21 which causes it to never actually reach the loop immediately beneath?

Also, I tried the same code with esp8266 and it worked, but as soon as I tried any esp32 same annoying message.
Does anyone know what to do with it? Any help is appreciated thanx.

@sharp scarab I've replied to this query on the Adafruit technical support forums

keen siren Feb 9, 2021, 9:48 AM

#

I'm new here.
I need to connect Sigfox to Adafruit IO.
I use the sht31 sensor (humidity and temp).

On Sigfox Callback→ "Body"
I have written JSON code like the following:
{ "value": "{customData#t}",
}

I guess the problem with JSON code...
What's the structure that is used by JSON codes when sending data to adafruit io?
Would you mind helping me?

Probably depends on what library you're using. Docs could be helpful https://io.adafruit.com/api/docs/

Hi! I'm trying to use adafruit.io with the circuitpython library for IO and adafruit_minimqtt running on a Feather M4 Express with the Airlift WiFi Featherwing. The problem I'm having is that io.loop() seems to block for 60 seconds then throws "MMQTTException: Unable to receive 1 bytes within 60 seconds" and I seem to have no way to either reduce the block timeout or otherwise take more control over polling for inbound messages. I want to be able to publish sensor data to IO every 30 seconds, but also receive messages on the subscribed topic (which I use for sensor configuration param setting) when necessary. Looking at the circuitpython minimqtt and io code in github, it indicates that the loop() call is "non-blocking" but I'm seeing different behavior. Am I missing something?

Hey guys I'm new to this discord, but it seems like the right channel to ask about this. I just recently bought the "Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE)" from: https://www.adafruit.com/product/2633. Although it wont yet arrive till a few more days, reading the datasheet and wiring guide I think there is a possible powering mistake.

#

In section 5.2 Operation Conditions", the typical supply voltage (VDD) is 3.0v, with maximum being 3.6v.

#

https://cdn-shop.adafruit.com/product-files/2267/MDBT40-P256R.pdf

#

but the wiring guide https://learn.adafruit.com/introducing-the-adafruit-bluefruit-spi-breakout/wiring says one should use 5v for power.

Adafruit Learning System

Introducing the Adafruit Bluefruit LE SPI Friend

All the goodness of Bluefruit LE, now in easy to use SPI

#

Is there something I am missing in the datasheet, would the BLE module work well with just 3.3v?

#

Thanks in advance for anyone who can help me out 🙂

keen dirge Feb 21, 2021, 9:20 PM

#

@lunar sleet take a look at the Schematic for the board https://learn.adafruit.com/assets/26205 there is a voltage regulator that takes Vin and creates 3.3V for the chip. Here https://learn.adafruit.com/introducing-the-adafruit-bluefruit-spi-breakout/pinouts#power-pins-2177358-2 it says you can power the board with 3.3-16V

#

Note:the silkscreen (on the back of the board) says 3-5V for Vin -- may not want to go to 16 😉

#

FYI -- followup questions may be better in #help-with-projects -- this channel is more for question about using the Adafruit-IO system.

Hiya @remote nebula - Just a heads up, since this channel is more geared toward AdafruitIO projects and platform, you may not get the help you're likely to need. Since it's an arduino project, I'd recommend asking in the #help-with-arduino channel, or perhaps better, since you're also working with stepper motors, trying #help-with-projects. However, please do not cross-post in multiple channels.

Good luck with your project!

I was wondering, I have 5 feeds that are updated every minute, is there a way that I can detect if they stopped uploading by checking the timestamp of the last upload and if its >5 then send a notification. I tried to do this with zapier and ifttt and wasnt able to get it to work. My guess is i'll have to write a python program to subscribe to the feeds and then compare the last values timestamp to the current time.

I was looking at your existing project for air quality monitoring, very cool! Wondering what you think of my tweak to how you're calculating the AQI. Would this be slower?

    AQI_25_range[35.4] = [12.1,35.4,51,100,"Moderate"]
    AQI_25_range[55.4] = [35.5,55.4,101,150,"Unhealthy for sensitive groups"]
    AQI_25_range[150.4] = [55.5,150.4,151,200,"Unhealthy"]
    AQI_25_range[250.4] = [150.5,250.4,201,300,"Very Unhealthy"]
    AQI_25_range[350.4] = [250.5,350.4,301,400, "Hazardous"]
    AQI_25_range[500.4] = [350.5,500.4,401,500,"Hazardous"]
    
    
    for key in AQI_25_range.keys():
        if pm25 < key:
            AQI_breakpoints = AQI_25_range[key]
            break
    AQI_val = ((AQI_breakpoints[3]-AQI_breakpoints[2])/(AQI_breakpoints[1]- AQI_breakpoints[0]))*(pm25 - AQI_breakpoints[0]) + AQI_breakpoints[2]
    
    if len(AQI_breakpoints):
      return AQI_val, AQI_breakpoints[4]
    else: 
      return []

It's late and I haven't tested it yet but I'm medium confident in it.
It's based on the wikipedia article from your guide, if you scroll allll the way down to the US portion https://en.wikipedia.org/wiki/Air_quality_index#Indices_by_location

Air quality index

An air quality index (AQI) is used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become.

I am beginner at circuit python, python.

I look at publishing data via the MQTT & IO_MQTT and, I guess ,it only takes a string value? I can't pass it a Label variable?

I want to send the entire contents of display, font, text, splash to be read in and displayed on another Maytag.
I could painfully do this by starting with the display group, send an array of labels or bitmaps or pallet item, then any fonts, but this seems horrible. Is there an easy way to pass "my screen" via RESP or MQTT with circuit python from a Maytag or esp32S2?

I'm trying to send "messages" to another Maytag, but quickly I saw sending a scribble or drawing with text is what I need to send. That seems to match a display object.

Any hints on what I should read? I could send:
" [ ( (0,0), 'Bitmapfilecontents 427 0x00000000...00000000' ), ( (40,30), 'string here is a string') ]
I could then read that any create the labels, bitmaps.

Great, thanks; there surely is a way but the examples on Adafruit always use a single sensor only, which for our citizen science projects is not enough (parents mapping their neighbourhoods while roaming the city with the stroller).

sullen imp Mar 14, 2021, 9:57 PM

Ha, no! Nearly all parents just own one. Two feeds instead of one would be great already. Using Fona here (Europe) will be too costly, and BLE connectivity is the way to go, as everyone and their dog/cat owns a smartphone ; )

sullen imp Mar 14, 2021, 10:27 PM

#

Hmm I'm honestly not seeing a way to do it unless adafruit io mqtt can decode a csv formatted stream and plot multiple plots?

#

Because you're sending text over UART to your phone, so it's just reading that and that is getting sent over MQTT to adafruit IO

#

So you could send csv data as text? But then adafruit IO would need to know what to do with that. I assume it's just decoding strings into floats on its side

eager kite Mar 14, 2021, 10:39 PM

#

But how can AIO separate CSV data and put it into two different feeds? The app has only one "UART RX: username/feeds/feedname"

eager kite Mar 14, 2021, 10:43 PM

Maybe the app coders know, or know how to have a second (or more) "UART RX: username/feeds/feedname". I mean, it's all the same, just an additional feed, as is possible direcly via WiFi.

sullen imp Mar 14, 2021, 10:44 PM

#

I think it's basically creating a serial terminal on your phone and then sending the output to a single feed

#

https://learn.adafruit.com/bluefruit-le-connect I was reading this

#

oh heyy

#

multiple uart mode

#

Are all your sensors connected to the same bluetooth enabled mcu?

eager kite Mar 14, 2021, 11:01 PM

#

Yep, a Adafruit Feather 32u4 Bluefruit LE right now.

sullen imp Mar 14, 2021, 11:01 PM

#

Hmmm this is for multiple MCUs

#

dang and I tried inputting csv style data into a feed and it just took the first number it could find

eager kite Mar 14, 2021, 11:04 PM

#

The recommended Adafruit Feather 32u4 Bluefruit LE can deal with several sensors no problem. Even the Flora Bluefruit from the tutorial I inked to in my initial question. It's just that all tuts only ever use one sensor.

sullen imp Mar 14, 2021, 11:05 PM

#

yeah I wish I had one I could test things on for you, but from reading it seems there's no way to do more than one feed

#

in the guide I linked they do two sensors, but they don't publish to a feed

eager kite Mar 14, 2021, 11:09 PM

#

Yeah, saw that, which is why I came here. The next thing we have will be GPS plus UV radiation. Again, that's two feeds. Using Fona for citizen science seems like overkill, as everyone and their cat owns a smartphone.

#

If you know the app coders within Adafruit, maybe they know how it is done, or maybe it's a simple patch to enable more than a single feed?

sullen imp Mar 14, 2021, 11:11 PM

#

I don't know them personally but I know some of them monitor this feed so maybe they'll see it? You could also open a github issue so that they are aware someone wants to do this

eager kite Mar 14, 2021, 11:13 PM

#

Yeah, thanks, GitHub issues section of the app is another idea.

eager kite Mar 16, 2021, 4:11 PM

#

So, adafruit says on GitHub it's not possible right now and not really in the pipeline. That's too bad, many citizen science project on the go would need such functionality.

placid belfry Mar 16, 2021, 11:30 PM

#

@sullen imp so are you now the Mqtt expert? I was building an app, then an Matt guide said download 6.2 beta. I switched to that on 2 of four boards, but even a connect no longer worked to io.adafruit.com. so I took 4 days off. I'm running metro esp32-S2 beta express boards with 6.2beta. A Maytag I have works at 6.1.

Do you know if 6.2beta MQTT example works on esp32? I've compared my code to the sample and there were changes from 6.1 for me to make in my code for 6.2 (port). It is likely I have simple mistakes.

I've bought one or two of most of the Adafruit boards so I should be able to choose a working board to continue software development if it is an esp32 difficulty.

sullen imp Mar 17, 2021, 12:50 AM

#

I'm pretty far from an expert. I'm gonna be on mobile until tomorrow but I can take a look then. It it makes a difference I'm using the mag tag to do mqtt

sullen imp Mar 17, 2021, 5:24 PM

#

placid belfry <@695351687602503752> so are you now the Mqtt expert? I was building an app, th...

Right now I've not actually tested MQTT on my magtag, just started writing code for it. I have used HTTP but it's supposed to be slower than MQTT. can you link the 6.2beta MQTT example you mean?

#

I'm writing code that's going to be using both so I'm focusing on making a child class that will let me call both from the same object, so I'm not even to the testing stage yet unfortunately

placid belfry Mar 17, 2021, 5:26 PM

#

I think my problem is io.connect, the docket pool not working.

#

Sovket

sullen imp Mar 17, 2021, 5:26 PM

#

oh interesting

#

yeah I'm pretty new to networking stuff, I wish this channel were more active with folks

placid belfry Mar 17, 2021, 5:26 PM

#

I set the magtag object even though it is a metro edp32-s2

#

Then getlocaltime. It connects and works.

#

But it doesn't connect after that.

sullen imp Mar 17, 2021, 5:28 PM

#

hmm

placid belfry Mar 17, 2021, 5:29 PM

#

My problem is I'm not too good at finding the code, or docs

#

hm, that seems to match what I've seen on examples

placid belfry Mar 17, 2021, 5:39 PM

#

My problem is I don't know where "socketpool" is

sullen imp Mar 17, 2021, 5:40 PM

#

yeah I don't really know much about that stuff, I just sort of take it on faith that it's a required part of the code

placid belfry Mar 17, 2021, 5:40 PM

#

I got this connected on a Magtag and running... Then I went to adding a bunch more code and a 4.2" display...

#

Now I'm throwing out tons of code and getting it back to where it wont fail.

sullen imp Mar 17, 2021, 5:41 PM

#

that's a good practice I think, take it back to basics and then add stuff slowly

placid belfry Mar 17, 2021, 5:42 PM

#

I'm a good ole C++ programmer... So, I have to do this faith programming myself and it is frustrating... Loosely typed garbage collecting nightmare

#

So, I'm wondering what gets set in Magtag for a REAL magtag versus a Metro ESP32-S2 Express Beta...

sullen imp Mar 17, 2021, 5:47 PM

#

well I'm wondering the the magtag.network stuff is separate enough that you can just run it on any ol' ESP32S2 board

placid belfry Mar 17, 2021, 5:49 PM

#

From one of the guides, I think this board, Adafruit Metro ESP32-S2 Express IS the same base board in the Magtag. So, it should be able to work, but I don't know if there is some code not getting initted because it can see something missing and sees this as a Metro board not a Magtag.

#

Oh, the Magtag has a Black boarder around all of the displays. This is a mistake in the driver. a Boarder release command needs to be sent to the displayio microcotroller on the e-ink display to turn off that boarder. When this is done, the display doesn't have a constant wide black boarder.

#

I assume there is some mechanism the base code "portalbase" sees that the board is a magtag and not the esp32 version.

#

Do you know if there is a "adafruit_metro" base class that can be used instead?
The adafruit_Magtag class looks harmless enough with a graphics, network class.

obsidian hedge Mar 17, 2021, 6:54 PM

placid belfry magtag = MagTag() print(time.localtime()) _local_time() print(time.localtime()) ...

obsidian hedge Mar 17, 2021, 6:57 PM

I think shift-enter is too. I have to think about it, since it's muscle memory. Just difficult when switching between Mac/Windows and Slack/Discord/Teams

placid belfry Mar 17, 2021, 6:58 PM

#

Hey do you know why socketpool or pool isn't kept globally with the wifi_module in adafruit_magtag/ ?

royal rapids Mar 17, 2021, 8:07 PM

#

placid belfry My problem is I don't know where "socketpool" is

socketpool is a module built into CircuitPython for boards which include an ESP32-S2

#

It's C code, not Python

#

https://circuitpython.readthedocs.io/en/latest/shared-bindings/socketpool/index.html#socketpool.SocketPool.socket

#

"Core Module" = C Code

#

@placid belfry Which code are you trying to use, I got my magtag out to help test, could you provide me with a link?

placid belfry Mar 17, 2021, 8:18 PM

#

Right now I'm just typing in the example minimqtt

#

Do you know if I can do magtag=Magtag()
For an metroesp32

royal rapids Mar 17, 2021, 8:34 PM

#

I do not think so, the magtag library includes and initializes hardware which the Metro ESP32 doesnt have

The "Resubscribe" I assume is added because a client can be sleeping. I guess the Adafruit server saves the subscription from the client name and reestablishes communication. So, does this mean I can subscribe a hard coded client name and then resubscribe over a period where my client died and was restarted? If not... Is there a way to persist the tcp stack?

I wish to screen SMS messages on Android Q looking for a "sender" and then "publish" a message to io.adafruit.com. Are there any sample Android apps for this, or is something like ITTT the thing that must be used to do this? (Or does OTTT not do this?)

You'd want to use IFTTT. Adafruit IO triggers can be used to send notifications via email, you MIGHT be able to pipe that to SMS.

@placid belfry @royal rapids I saw one learn guide on Alexa but it was for triggers to send something to your microcontroller coming from Alexa. I want Alexa to pull data from Adafruit IO and not sure where to start. Something like... "Alexa, what temperature is it in the garage".

placid belfry Mar 24, 2021, 6:25 PM

#

@holg that one is covered in a guide. I can't remember which one but it is how you integrate a device to Alexa. I'll let you know when I get there. I usually read a few guides a day.

@placid belfry I'm not sure if that's possible, the guide which uses Alexa/IO sends data to IO using IFTTT as a bridge

#

not sure if it's possible because I don't know much about the Alexa SDK and don't have one.

Ha... that's easily fixable!

small kelp Mar 26, 2021, 12:48 PM

I'll do some additional research on it soon. Might be a good candidate for a new learn guide.

#

Now I have another question.

#

I am using PubSubClient on an ESP32 to publish data for temperature and voltage to two different feeds. The first feed publish always works but the second does not always reflect on Adafruit IO but always sends successfully. I originally had no delay between the two but have tried using 500,1000,2000 and still have issues with the second publish. Is there a limitation to how fast I can send data? In testing I was only sending two messages every minute but even sending two every hour, I experienced the same issue.

#

I am using the free tier.

Hello everyone! I'm a complete beginner so while playing around with code in my internship i messed something up. Here we have 4 Raspberry Pis that controll some LED stripes. I got an error to my code saying "unable to import board, unable to import neopixel". I found on the internet that maybe Ardafruit-Blinka packages were missing, so i tried to reinstall it in one of the Pis with this command "sudo python3 -m pip install --force-reinstall adafruit-blinka". This rendered that Pi useless, and now its not responding to any code. My supervisors said that there may be a difference between Package versions so i checked at the other Pis and they were running on Adafruit-Blinka==2.6.1 version, while the first one is running on 6.4.2. Does anyone know why this happened or what the differences between the versions are?
Would be very thankful to any response

WiFi devices like Comcast's Xfinity require a browser so you can provide your credentials. After authentication you have internet access. It's called a "captive portall", like you have in airports, hotels, etc. that provide free access. Maybe you can use your smartphone as a WiFi hotspot to circumvent that problem.

Hi,

I'm not sure if this goes best under help-with-arduino or help-with-adafruit-io, but I have the Adafruit Feather nRF52840 Express and want to modify the Bluefruit connect app and to develop upon the core codebase so I am currently working through #3 part 5 of the Arduino Set Up Support on this page. https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide?view=all

However, when I download the Adafruit_nRF52_Arduino repo all of the files within under libraries -> Adafruit_nRFCrypto @ 50131a5 do not download and that folder is blank, however I can see that when I click through the page there are in fact files there but for some reason are not downloading.

As a result when I try to run the Arduino IDE on my MacBook and select the Adafruit Feather nRF52840 Express board to run I receive and error saying “Invalid library found in /Users/Documents/Arduino/hardware/Adafruit_nRF52_Arduino-master/libraries/Adafruit_nRFCrypto: no headers files (.h)

So I want to know if there is something I’m doing wrong or some problem with this link https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide?view=all or the download setup on the link since I’m unable to receive the .h files needed within the libraries -> Adafruit_nRFCrypto @ 50131a5 -> src folder

OK, I finally think I've got it licked. First, tip for anybody experiencing problems, import adafruit_logging and init a logger. After initializing the mqtt client, before connecting, set the mqtt_client.logger to the logger you initialized. This will give much more descriptive error messages, and tell you where it failed. In my case, the key was slightly different from the feed name, and the raised exception didn't detail this information, but the logger does. From here, I was able to fix these problems and subscribe to the feed, even though it looked like it was failing before feed subscription.

Sorry for the late response. I’ve got my FeatherS2 connecting and successfully posting to adafruitio via MQTT now, so I think what you posted is a different problem. Have you tried init’ing a logger and setting the MQTT instantiation logger to it to see what’s going on in that object?

@modern widget my issue is with a PyPortal trying to receive data from AIO. "Strange things are afoot at the Circle K."

modern widget Apr 26, 2021, 12:42 PM

#

@obtuse marsh @lean swan - Ok - my issue is with receiving data as well. Specifically, I get an error when calling the "loop" function (I get an "EBADF" error). This sounds like a know issue at this point, so I'll wait for a resolution

Hey. I have an adafruit MPR121 capactive touch sensor, and was wondering if it works with sparkfun's SAMD51 thing plus.

#

And if yes, what ports can I hook the MPR121 onto? I would really prefer not to use A4 and A5 as specified in the docs.

@ornate pagoda Hi Kattni! I'm trying to use the adafruit mini gps pa1010d module with the micro:bit. I connect the sensor, get the green light and the red PPS light is blinking. The I2C read command for the micro:bit looks like this: i2c_read_number(address: number, format: NumberFormat, repeated: bool): number But I'm not sure of the I2C adress and the number format. I have tried I2C adress=66 and format=UInt8LE but that didn'twork. Any suggestions?

@uneven flax I have no idea! It's best to avoid pinging individuals unless you're already in a conversation with them. It means you're limiting potential answers, and unnecessarily pinging folks. This question is probably better posted to the #help-with-projects channel. We discourage cross-posting, but I would ask that you post your question to the other channel because it may not get seen in this channel. Please be patient once you post your question as most of the folks on this server are community members who help out when they can.

I just received the Adafruit Zero4U Powered USB Hub (without the POGO pins) today and am trying to find out which of the Pogo Pin pads on the back of the Zero4U is which. I haven't been able to find the pinout or electrical diagram for it. i.e.- where do I solder each wire to power it up?

#

There are 4 pads: PP1, PP6, PP22, & PP23

#

https://www.adafruit.com/product/4115#technical-details

Zero4U - 4-Port USB Hub without Pogo Pins

One can never have enough socks, or USB ports. Add some more USB capability to your Raspberry Pi Zero, or any other single-board computer with the Zero4U!This is a 4-port USB ...

#

Here's the image from the website, although mine doesn't have the "ALT 5v IN" solder pads on the back. It must be a different revision

neat charm Apr 27, 2021, 3:36 AM

#

It looks like the pogo pin assignments match the RasPi Zero pads, so PP1 = +5V, PP6 = GND, PP22 = USB D+, and PP23 = USB D-.

Hey guys, I am trying to send JSON data via MQTT in order to create several feeds within a group at once. Everything seems to be going well on the surface and under monitor -> live data it is showing that adafruit.io is recieving the data. BUT for some reason, it is not creating or showing new feeds under the group. Has anyone else encountered this issue or knows how to fix it?

#

#

mighty ridge Apr 30, 2021, 10:43 PM

#

@bright coral make sure you're using a unique client id. don't expect something like "esp32-client" is unique

#

@ember quarry maybe you're maxed out on a free account ?

For those with a PyPortal, I just submitted a firmware update issue on Github - PyPortal Pynt ESP firmware update issue #27 (https://github.com/adafruit/Adafruit_CircuitPython_miniesptool/issues/27). If anyone has a similar issue, please post any information that can help the good folks at Adafruit to resolve this. Thanks so much!

Hello all! I'm modifying some MQTT code so I can read FROM IO (gas sensor data). The line I have is: mqtt_client.publish(rx_feed) but that line is to publish data. If I want to read the data from IO, is there a line something like mqtt_clien.READ(rx_feed)? Thanks!

obtuse marsh May 3, 2021, 6:40 PM

#

Never mind... Got it working! 😃

obtuse marsh May 4, 2021, 8:44 AM

Actually, got the code itself to work but can't integrate it into the PyPortal UI example because UI code calls on the PyPortal board... Back to square one. 😩

There's these from the learn guide:

mighty ridge May 7, 2021, 2:50 AM

thanks but neither of those use the adafruit_io circuitpython library

obsidian hedge May 7, 2021, 2:56 AM

#

I thought I had one on my MagTag, but apparently, I erased the device to test something at some point, and then erased my memory of erasing it 🤦

mighty ridge May 7, 2021, 3:02 AM

#

well apparently when I tried the MQTT style it wouldn't work, but the HTTP one does. this one : https://github.com/adafruit/Adafruit_CircuitPython_AdafruitIO/blob/master/examples/adafruit_io_http/adafruit_io_simpletest.py

#

I feel like the magtag library might offer a wrapper for all that ssl and sockets stuff but the documentation is so hard to find.

obsidian hedge May 7, 2021, 3:08 AM

#

You're right, it does offer a wrapper

#

And it's a bit of a dig to find it. But for now, these are the ones you should need:
https://circuitpython.readthedocs.io/projects/magtag/en/latest/api.html
https://circuitpython.readthedocs.io/projects/portalbase/en/latest/api.html?adafruit_portalbase.PortalBase#adafruit-portalbase-network

#

Since Magtag inherits from PortalBase, which, through the network property, has AdafruitIO wrappers, such as get_io_* and push_to_io

It can be one of these issues, or a combination of them:

Your SSL-certificate on the device is not up to date
Your Adafruit IO key in your code is wrong
Your ESP32 has not established a connection with your router or smartphone hotspot
Your router has no Internet connection

Not directly. You have to have a bootloader in the internal flash which would transition to loading an application from SD Card or something like that.

Hey guys I'm having an issue that could be something to do with my router but i'm not sure. I currently have 3 ESP32s connected to my network and to Adafruit IO and they all work fine but I just tried to connect another one and the serial monitor stays stuck on "disconnected from adafruit io". Ik it's not a device number issue because when I disconnect one of my other esp32s it still doesn't work. I've tried running the code on a different esp32 but it still doesn't work so it's not device specific. Any ideas on what the issue could be? I'm pretty close to just creating a single "smart hub" that connects to adafruit io and have all the other esp32s connect to the hub via ESP-NOW but i'd like to know what the initial issue was. Thanks!

I'm not sure what issue you're seeing but for Adafruit IO, if the discord doesn't work, the Forums are a great place to ask. They're more of an official support vibe there whereas here there's more a community help vibe (but lots of Adafruit folks helping too).

I'm trying get the bluefruit feather to receive data over adafruit IO via the Bluefruit connect app. However, it doesn't seem like that flow exists. You can send data back and forth from the App to the Feather, and from the Feather to the App to IO, but is there a way to get a feed data from IO -> App -> Feather ?
