I am back this week and getting started for the morning. Working on a new game. You can follow along on YT: https://www.youtube.com/watch?v=_vdaKs-_wVE or twitch: https://www.twitch.tv/foamyguy_twitch

[clever summit]

Trying to remember how to publish a Python package so it can be downloaded with pip.

Yes, was not that hard.

python3 setup.py sdist bdist_wheel
twine upload dist/*```

But I messed up something, there is no project description on PyPi. Lol.

[inner spade]

👋☕

[clever summit]

Lol. just got a mail from PyPi. - "This email is notifying you of an upcoming deprecation that we have determined may affect you as a result of your recent upload to 'newsbinpro-client'."
[17:09]
Seems you have to use _ and not - in the library name now.

[paper peak]

does that email have a link explaining that in it? I can't find anything in the pypi help

[clever summit]

"Specifically, your recent upload of 'newsbinpro-client-1.0.0.tar.gz' is incompatible with PEP 625 because it does not contain the normalized project name 'newsbinpro_client'."

So PEP 625 it is then. I always used a "-" in my Python libraries.

[paper peak]

I think the name as searched is ok with a hyphen. can you point to your repo?

[clever summit]

And I uploaded it to the production PyPi by mistake. 🙂

https://test.pypi.org/project/newsbinpro-client/1.0.0/

Now with the proper name in the Test PyPi.

NO. Still wrong name?!?

[paper peak]

I see newbinpro_client in PKG_INFO. did you change that?

[clever summit]

That should be generated.

It says Uploading newsbinpro_client-1.0.0-py3-none-any.whl though, so it did pick up the file name correct.

[paper peak]

src/newsbinpro_client.egg-info/PKG-INFO still has -client

[clever summit]

Argh. Seems issue was I was running older versions of sdist and bdist_wheel...

Question for the team... the I2c digital potentiometer (non logarithmic DS3502) mentions the analog voltage controlled can be in the range of 4.5-15.5volts, but the example takes 3volts (Vcc level) to the wiper / Vhigh, what am I missing?

[steady osprey]

I see and hear you!

[timid plover]

great to be here with you all

[steady osprey]

Learning some painful but useful lessons about how to properly support 3D models when printing.

[still bane]

hi!

[steady osprey]

I've done lots of C/C++ in my career, although mostly for desktop. How much does C/C++ differ from chip to chip? I'm guessing CircuitPython abstracts those differences away, right?

[unreal bay]

Similar with Arduino core abstracting the vendor sdk into standard peripherals. Hey all 👋 Zephyr Crew

[tulip canyon]

👋

[unreal bay]

Accessing usb-ethernet/modem devices would be cool, along with acting as one maybe

[timid plover]

I wonder if @strong acorn was asking for CP to get network access over a USB connection on a PC, or perhaps it is providing network access from a PC to the CP host ?

[unreal bay]

For the last bit More like serve a closed network/ lan

[still bane]

metro RP2350 computer sounds cool

[unreal bay]

I share the board farm dream, we're trying wokwi for some stuff but i2c devices need chip emulation written (c/verilog) which isn't too hard but unrealistic.
I want to build a cheap reliable mini farm/cluster with analog matrix switches moving daughter devices (sensors etc) onto each board

Hehe yeah, hence share the dream.
There was a good article on the CV chips recently

[shell mason]

https://tenor.com/view/profile-gif-5764368459933671496

[unreal bay]

I've got enough sensors and boards now, excluding the switches (enough for PoC), but the setup will be insane

[shell mason]

engineering setup next?

[still bane]

The Renode port might be useful for the I2C testing thing

[unique cairn]

J P, this webpage has Python learning resources: https://learn.adafruit.com/welcome-to-circuitpython/how-do-i-learn-python

[still bane]

yeah true... my point of reference is the hardware simulations that xobs built for bunnie's Precursor hardware

[unique cairn]

Is there any way of running multiple CircuitPython programs simultaneously on a single MCU, with the ability to start and stop them individually? I think this would be a prerequisite for a CircuitPython computer.

[timid plover]

what support is there for having multiple CP computers sharing information with each other - in parallel

[eager matrix]

Is there plan to add more adafruit board to the supported boards on zephyrproject as this moves forward?

Also - Hi Scott.

[unique cairn]

Ethernet/CANbus networking?

[unreal bay]

Are multicast packets supported?

Think so, required for mDNS

[still bane]

on upstreaming board defs...
Have you thought about how to handle SPDX headers and developer certification of origin (DCO) for upstreaming to Zephyr? They seem quite serious about Apache-2.0 licensing and DCO sign-off commits.

https://docs.zephyrproject.org/latest/contribute/guidelines.html#components-using-other-licenses

[clever summit]

🇸🇪 👋

[timid plover]

Given that CP is one thread per micro, if one wanted multiple threads - and they ran on multiple CP microprocessors - how would the coordinate with each other - that's the sharing information in parallel I was referring to

[still bane]

Context: Suppose I make a circuitpython PR to add a board to your zephyr-cp port, then someday maybe you want to upstream it. How do you avoid an upstream PR review hassle over MIT vs APACHE-2.0 and DCO sign-off commit messages?

lol

[tulip canyon]

Webserver and host has come a bit further

[still bane]

sounds efficient

[tulip canyon]

Asyncio with Requests would be neat

[eager matrix]

which licenses are being used? ( I know I could look it up but I'm feeling a bit lazy).

Is part of the benefit to putting CPy on top of Zephyr that it won't be hard to use CPy on most Zephyr supported boards, even those that aren't from Adafruit.

[timid plover]

where is subsys and zephyr.dts in your repository
I may have missed submodules

ah - thanks !

[still bane]

Have you identified any missing pieces that might make a good project for folks that want to contribute to CircuitPython on Zephyr?

[unreal bay]

Presumably if you remove that qspi pin def stuff but ask for the chip family default DTS to be included too then could rely on any supported qspi flash?

[unique cairn]

Have you ever been to a community makerspace? It would be a good place to house many of the development boards that you don't use too often. They might even have ones that you don't.

[unreal bay]

So have to name each variant instead. Not end of the world, just less than ideal

[still bane]

yeah, that's a great answer. lots to think about

I'm really curious about using ESP-AT to do WiFi and BT classic with an AirLift module. Might let me do BT keyboards and BT gamepads as input to CircuitPython

seems that maybe Zephyr doesn't have any existing support for BT HID

but ESP-AT over UART would probably work

there is some BT classic stuff, but it seems like most of what they have relates to BLE

advantage of ESP-AT is that it would be modem style, like the cellular stuff

could you talk a little about your current plan for how to progress through USB support, flash support, then whatever comes next?

what do you think about RPi Pico W?

[eager matrix]

I'm also looking for Zephyr on Daisy Seed and will probably make a port as soon not long after I get up to speed with Zephyr.

[still bane]

Mentioned that one as I remember seeing people wanting BT support on Pico W

ohhhhhh

[tulip canyon]

Will CircuitPython depricate any board not supported by Zephyr?
Any other past boards dropped in say CircuitPython 10?
https://docs.zephyrproject.org/latest/boards/

Ha ha a have a Sony Spressese. It's garbage lol

I bought it for Edge Impulse support

Edge Impulse is another great product I'd love to work with CircuitPython

My mom often woke us with " Rise and shine Sparkle Plenty!"
(Sparkle Plenty was an obscure character from comic strip or radio)

TI has some really good tech talks about field oriented control. I think you could almost make a brushless sensorless bldc work as a stepper. You know exactly when each pole is passed and how far it is between each one, by using a second pin to watch the current, you can even know how hard it's pushing or being pushed.

[tulip canyon]

My challenge is a hydration pack, it sloshes etc. I'm thinking weight might be the best method

[sand lotus]

One of the thing that irks me about Keurigs is there is no water level sensor and the water level is always hard to see. Improving your coffee ingestion efficiency is always a worthy project.

@gray obsidian this is for "hub75" style RGB LED matrices. That project says it's based on WS2801 or APA102. I also did a library for neopixel LEDs on the Pi 5 which are similar but not quite the same as WS2801 / APA102.

If you have an RGB matrix connected to a Pi, you can run that as Flaschen Taschen backend:
Ok, I see, it does support this kind of display, perhaps. Well, the way the pi5 drives the display is different than older pi versions -- https://github.com/hzeller/rpi-rgb-led-matrix is not supported on pi5, that's why I had to do this code in the first place.

Lots of stuff
https://docs.zephyrproject.org/latest/boards/index.html

[glad mortar]

and you get a lot of companies doing ports to Zephyr on their own these days, as long as CircuitPython uses the abstraction subsystems for the typical peripherals new support should not be far from it being a weekend thing to get supported in CircuitPython

Question: Can Gen AI do HW design, schematic capture or PCB layout?

[tulip canyon]

Question: Is Brushless DC Motor Driver equal to ESC?

[noble grove]

The term ESC is typically used in RC aircraft community but BLDC is basically the same, just more general.

[tulip canyon]

ESC usually super high 20-30A

[sand lotus]

esc means electronic speed control. any motor driver capable of speed control is an esc.

[nova totem]

And don't hook your regular LiPo to an ESC that wants that 20-30A or "bad things" may happen

[sand lotus]

esc is mostly an RC term yeah. Adafruit has some motor drivers in the store that are also ESC's it just depends on the type of motor and driver.

most RC's are a multiple of 3.7v. 7.4V is simply 3.7x2.

11.1V is 3.7V x 3.

[nova totem]

I have one that is 11.1V that I have thought of using if I need more power for some project that can draw a fair amount of amps. But really only good for 10-15 minutes at that draw

[sand lotus]

So an S2 or S3 battery is just a multiple of a 3.7V battery but also can require far higher amperage.

With a voltage buck you can use an S2 or S3 battery for 3.7V projects and will have a ton more amps at your disposal. Like everything right tool for the right job. Mixing batteries and drivers not meant for each other usually doesn't end well unless you really know what you're doing.

Keurig does that with a pre-fill. If it doesn't completely fill you get like half a cup of coffee.

So can't ever let the reservoir get close to empty.

[tulip kestrel]

How close is the fire to you JP

[inner spade]

Perhaps it self-cleans due to ultrasonic vibrations? 😄

[shell mason]

lars super cleaner

[lavish patrol]

Not as silly as it sounds. DSLRs have such a system to keep the sensor clean.

[sand lotus]

Probably just dip it in some vinegar or bleach then air dry. If the reservoir gets moldy then have bigger issues anyway.

The problem with floats is they do tend to grow mold since most are in water all the time.

[tulip kestrel]

How close is the fire to you JP

[old surge]

Eh, just have the weight outside of the tank and wipe down the float when cleaning the reservoir

Maybe a load cell measuring the weight of the machine? (As a mold-free alternative)

[clever summit]

I bought a machine to print with, not to fiddle with.

[sand lotus]

I've heard some AMS systems waste so much filament that has to be wiped off. End up going through spools slightly faster. If that's the only downside then it's a win/win.

[shell mason]

on holidays i got creality hyper filament

[unreal bay]

you can set the material purging (colour bleed avoidance) to go into the model as infill

[shell mason]

this is creality CFS https://img.fantaskycdn.com/4023957dad32db321fe302c5b23dbe87_1008x.jpg

DJdevon or 16colors right

you could print nice with hueforge

You can do soluble BVOH supports with an AMS/MMU, that can come in pretty handy sometimes

what is the timeline for porting daisy seed to zephyr / circuitpython?

i was just about to make a PR with my initial port of Daisy Seed 😄

[sand lotus]

I have one of those too. A lot of projects got ahead and I forgot about it. I can help test your zephyr port for it when the time comes. Don't imagine many people have them.

[glad mortar]

oh right that board, yea is a bit weird how hush hush they are about their boards

[winter zinc]

just wondering how soon it will become obsolete 😄

[timid plover]

cool you have USB working!

[sand lotus]

I'd be willing to help test that port too Snakey.

random bits are the spice of life, keeps you on your toes.

[still bane]

that hub question sounds like a good Ask an Engineer thing

[nova totem]

Replaced my motherboard over the holidays and USB devices in general finally led me to reinstall Windows.

[sand lotus]

k.sleep? sounds like heresy.

circuit python scanning example or zephyr?

nvm, zephyr is way outside my wheelhouse.

[paper peak]

it's not imminent by any means. TinyUSB has to start working. There may be a very limited port, but it may lack functionality.

[glad mortar]

there is a scan function in the wifi manager but not sure there are examples for it specifically

[still bane]

(.venv) $ grep -r scan * | grep wifi
net/wifi/shell/README.rst:scan, connect, and disconnect.  It also enables the net_shell module
net/wifi/shell/README.rst:   shell> wifi scan
net/wifi/shell/prj.conf:# printing of scan results puts pressure on queues in new locking

[glad mortar]

https://docs.zephyrproject.org/latest/doxygen/html/group__wifi__nm.html

[sand lotus]

I found one for the nordic sdk? sure you saw it in zephyr and not nordic sdk?

[glad mortar]

but yea is not much samples for using it

also check https://docs.zephyrproject.org/latest/doxygen/html/group__wifi__mgmt.html

[twilit steeple]

https://github.com/zephyrproject-rtos/zephyr/blob/576b27a3f74c69552df851e8c97a8534462dc15e/drivers/wifi/nrf_wifi/src/wifi_mgmt_scan.c

[glad mortar]

that is a driver implementing the wifi manager

not something you interact with directly

you can probably just use the source for the wifi shell to cobble things together https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/net/l2/wifi/wifi_shell.c

yea the network manager is very abstracted, if you implement that instead of specific things like Wifi and Ethernet individually you get actually loads of ways to do IP without needing to specifically care about the transport

like WWAN/LTE etc just comes for free

[still bane]

FWIW, I know you're not into the shell, but I just tried doing a west build ... net/wifi/shell ... for Raspberry Pi Pico W, and was able to use wifi scan in the shell over UART. It just worked. no fuss.

[twilit steeple]

https://github.com/zephyrproject-rtos/zephyr/blob/576b27a3f74c69552df851e8c97a8534462dc15e/subsys/net/l2/wifi/wifi_mgmt.c#L428

[glad mortar]

yea agree, its bad

the shells are super useful but they should not be an excuse to not have a sample

[twilit steeple]

Does this look like the sample you were looking for ?

[still bane]

I hear you. return 0; is a bit uninformative.

[glad mortar]

that is the implementation of wifi manager

anything thats not in the sample directory is not a sample 🙂

you will need to interact with the wifi and network manager if you don't want too loose SoC abstraction

thats the subsys they implement to enable wifi

[still bane]

(.venv) $ grep -r SHELL_CMD_REGISTER * | grep 'wifi\|net'
drivers/wifi/nrf_wifi/src/wifi_util.c:SHELL_CMD_REGISTER(wifi_util,
drivers/wifi/eswifi/eswifi_shell.c:SHELL_CMD_REGISTER(eswifi, &eswifi_shell, "esWiFi debug shell", NULL);

subsys/net/lib/zperf/zperf_shell.c:SHELL_CMD_REGISTER(zperf, &zperf_commands, "Zperf commands", NULL);```

(grep command to locate files that register shell commands)

this appears to be the implementation of the wifi scan shell command: https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/net/l2/wifi/wifi_utils.c#L277-L306

[glad mortar]

those are general helper functions, the shell implemention is what I had posted earlier

https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/net/l2/wifi/wifi_shell.c

https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/net/l2/wifi/wifi_shell.c#L1093 initiates a scan

[still bane]

oh right... that's the same file you already posted [edit: never mind... I think I actually pasted a link from the wrong tab]

[glad mortar]

their samples all use standard Zephyr stuff for the most part, they do have a couple libraries they add but not for major stuff like network management

you can get away with using an upstream Zephyr and include some of their specific libraries if you don't want to use the whole nRF SDK package, though they do maintain a down stream copy of Zephyr that has some different patches

[still bane]

looks like the scan implementation is spread across several callback functions in that file

so, would a focused wifi scan sample, minus all the shell stuff be useful to you?

I'm about ready to try making some samples of my own for the Pico W board

[glad mortar]

but yea I think the shell code should be enough for the parts you need, it shows you how to interact with net_mgmt for the wifi specific stuff, for net_mgmt itself you get a few samples in main

[timid plover]

try it ( chatgpt )

[sand lotus]

chatgpt: please port circuitpython to zephyr. easy as that. 😛

[glad mortar]

the tldr is you ask network manger to do stuff and pass it command like scan request command and then you listen for events like "wifi scan result"

[timid plover]

maybe overloaded functions?

[glad mortar]

lol yea no thats all made up

[sand lotus]

oh that's just a way chatgpt does for loops

[winter zinc]

WIP draft, but you're welcome to try it https://github.com/adafruit/circuitpython/pull/9974

[glad mortar]

@rapid hornet https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/net/l2/wifi/wifi_shell.c#L1093-L1127

[timid plover]

another place to look for sample code is in tests

e.g. tests/net/wifi/wifi_nm/src/main.c
which has a call to wifi_scan

[sand lotus]

I think only staff has access to the archive or whatever the pre-release thingies are called. I think I'll have to wait for a build.

[still bane]

timonsku... sorry for the confusion. I think I actually pasted a link from the wrong tab earlier

[winter zinc]

Oh, didn't know that, I made it ready for merge.

[sand lotus]

I can't remember what they're called. architype or archive, can't remember the word that github uses for it.

[timid plover]

thanks for clarifying sysbuild 🙂

that I misheard

[still bane]

sysbuild?

https://docs.zephyrproject.org/latest/build/sysbuild/index.html

[glad mortar]

I think wifi should be doable to add

[timid plover]

you mentioned that sysbuild is build on top of cmake - I was looking at the text files in cmake Modules folder - there are over 100K lines of text ( that they invented a new interpreted language for )

what was wrong with other scripting languages

[glad mortar]

its not too much stuff

[still bane]

re wifi first or merge sooner... it would be cool if the merge happens in a state where people can try adding more boards.

so maybe whatever would result in less churn?

[timid plover]

so to be a CMake master, I need to learn a new language, and understand which libraries I need to add to my vocabulary

[still bane]

when you say "wifi", which parts of the API would you need working (scan, connect, and ...?)

[glad mortar]

you might want to think about having a global network manager instance that you interact with and that wrapping things for more specifics like a wifi scan as all interfaces make use of network manager, would just be a lot of duplicate functionality in the end

[timid plover]

227K lines of C++ code in the cmake-3.28.3/Source

[glad mortar]

yea essentially the same really

thats why I mean maybe have shared abstraction towards the CPY side

[still bane]

for Ethernet... which hardware are you thinking of? Blinka on Pi? Ethernet FeatherWing?

[glad mortar]

the wifi tidbits are just 3-4 extra stuff you request from net_mgmt

yea like have a "networking" bit that handles the interaction with zephyr's net_mgmt

gets clear if you look at the wifi shell source code or that network manger test

oh yea no for sure, just mean how you manage the port side

yea the 7000 series stuff does not take any firmware, it just has the radio firmware, which is unfortunately always a blob with every vendor

it is 😄
but a bit less so

the radio is still a blob but the packet layer is open, which is great

yea one big reason for sysbuild was afaik that it allows for linking in external blobs for parts like that, thats one of the main things why Nordic has their own fork and stuff

I think its mostly about having it in the repo or not, the idea is that blobs would get pulled through an external module

because licensing of blobs is usually very complicated

[tulip canyon]

That Station Mode and AP Mode look interesting although I don't have.a usecase myself
https://docs.zephyrproject.org/latest/samples/net/wifi/apsta_mode/README.html

[still bane]

when you say "scanning example" do you mean a zephyr thing or a circuitpython thing?

oh... so run code.py, see what breaks, fix the first one, repeat...

[timid plover]

is the .bin file a binary blob or an output from your linking?

the one that was mentioned in the error message

[glad mortar]

it should link in if you add CONFIG_MBEDTLS

in KConfig file

could be enabled by another option like networking

yea all external libraries are in modules exclusively

there is a mbedtls folder

the source itself is still in a submodule, they don't touch that the modules is essentially CMake wrappers and maybe some extra functions to have it play nice

west will pull in all the external repos for you

if you don't have it on disk you might need to do west update

[still bane]

in my zepyhr workspace, west puts the source in ../tools/net-tools/mbedtls-2.4.0 above the zephyr repo

[sand lotus]

if/when zephyr works will i notice any difference in using circuit python? is all of this only for the core stuff?

[glad mortar]

yea external repos get put outside the zephyr tree

so whatever west workspace you have setup

[still bane]

did you look in tools/net-tools?

[sand lotus]

sounds good to me. slap a sticker on it. sold.

[glad mortar]

that is not the path you would include

look in your build folder if you want to verify that it actually gets put in the right spot

[still bane]

there are also mbedtls include files scattered all over various directories under ../modules/ ../bootloader/ and ../tools/ in my workspace directory

[glad mortar]

you should not need to worry about linking against it manually, if it doesn't get pulled in then something is wrong on the CMake configuration side

the include path seems to just be #include "mbedtls/..."

https://github.com/zephyrproject-rtos/zephyr/blob/main/tests/crypto/mbedtls/src/mbedtls.c

in that test they build with
CONFIG_MBEDTLS=y
CONFIG_MBEDTLS_BUILTIN=y

is your include path in your sources correct though, didn't you have a lib/ in there?

ooh okay, so you aren't getting it passed on into the cpy buildsystem is what you mean?

From Wikipedia, the free encyclopedia

Gigabit Multimedia Serial Link, commonly referred to as GMSL, is a serial link technology that is used for video distribution in cars. It was developed by Maxim Integrated. Maxim Integrated was acquired by Analog Devices in 2021.

using shielded twisted pair is a brilliant way to detach some build components from the main body.. the difference in doing shielded vs unshielded is trivial, so it's something easy enough for makers to do on their own

[sand lotus]

looks like the routing in the example requires trace route length impedance matching. can't remember what that's called.

Matter connect to the valve linked above

That'd be nifty if you could maybe connect an ammeter between the unit's plug and the wall outlet to trigger a read upon sensing a ramp up in current (from use)

That would work.

[glad mortar]

yea I mean its cheap for them

guessing dropped messages are received packets that were not processed ?

[old surge]

How's it going in WA? It's been sub-freezing temps here all week

[old surge]

Oh, thanks, eh

[nova totem]

We actually finally got to about freezing temps and not -30, earlier this week was brutal

[old surge]

We also made it up to freezing today at last 😅

[old surge]

(I haven't seen -40 in over ten years, but I kinda miss it)

[nova totem]

... and after 30 seconds back in it you will be good for another 10 ha

[glad mortar]

wdym turn on?

[gusty wedge]

All are welcome to come and hack in Costa Rica. It's about 23C, very little clouds so I can see the ocean from here, the sunset is about to start (4:30pm here), and the tucans are about 5m from the window I have in front.

[glad mortar]

for logging maybe implement a CPY logging backend, then you can get everything that goes through the logging subsys

[unreal bay]

Are there any current Circuitpython boards that use the BW16 WiFi/ble chip (ai-combo AT command set)?

Or other AT WiFi boards

[timid plover]

did you have an example program to compare with from the sdk ?

[glad mortar]

and no you should not need to do anything, thats all taken care of by the driver

[unreal bay]

I'm hoping to not write AT stuff

But when I looked it seemed easier to put Micropython on the BW16 coprocessor 😁

Or port airlift/Nina

[glad mortar]

you would also be able to get printk's
a lot of subys and drivers log through the logging system, might make lifer easier down the road if you don't have a seperate log view for the zephyr side

what are you looking for atm?

[timid plover]

where is the error issued in the source code ?

[glad mortar]

the error sounds like communication doesn't work, do any other wifi related actions work before that?

[gusty wedge]

Bit OT, but I'll probably watch after this, a talk from 3C about hacking the wifi on the esp32, if I'm reading it correctly they have a complete "free" wifi stack for the esp32. And they were able to port it to the esp32c3 as well.

[glad mortar]

so driver includsion is dictated by devicetree, if the device is not defined in DT then it will not compile in the driver

other thing is enabling the relevant subsys in Kconfig, in thise case should only be network

so you are checking if the device is ready?

you would get an error there if its not defined but if you currently use the DK definitions you shouldn't need to do anything

oh and for samples, its a good idea to check the Nordic fork, they have more samples there for their own devices

I mean you don't have to use them verbatim, the things they call is just Zephyr APIs that are not under their license

[timid plover]

so even looking at the nordic fork taints your code ( potentially ) ?

( how do you ensure that autocomplerte doesn't bring in licensed code ? )

would copilot help bring in the comments too ?

[glad mortar]

yea am surprised it doesn't suggest you the whole block

thats also my primary use of it, generate giant boring to write switch statements

[proper prawn]

Hi Scott, and all present.

[old surge]

(I keep meaning to ask our DeepDive hosts if it wouldn't be terribly inconvenient to bump up the text size a smidge)

[timid plover]

so you don't use the config tool to change settings - just to view help?

[timid plover]

what is you screen size?

[old surge]

Ooo, that's lovely - thanks much!

[glad mortar]

you can configure this in the logger

it drops when it can't keep up, you can force it to log no matter what

the message dropping

but yea it should also tell you where the log originates from

every module defines a logger, not sure why the info is dropped here

sec I can give you a snippet for the dropped messages

what backend do you currently use?

CONFIG_LOG_SPEED=y
CONFIG_LOG_MODE_IMMEDIATE=y
CONFIG_LOG_BLOCK_IN_THREAD=y
is what I usually do if I want immediate log and no drops

but it messes with timings

you could also additionally log all zephyr stuff over RTT

and if you want to forward printk's to the log subsys
CONFIG_LOG_PRINTK=y

oh and you can increase the buffer for log too which can help
CONFIG_LOG_BUFFER_SIZE=32768 f.e.

[timid plover]

embedded.fm is a great podcast

[glad mortar]

that usually fixes issues if you deferred logging

which prints are you missing?

CONFIG_LOG_DEFAULT_LEVEL=4 should get you there

but that gets you everything that isn't explicitly configured to another level

so includes kernel

what irritates me is that you don't get any subsys names in your logs

are the logs you get all your own?

might be that you don't have logging at all

because printk is seperate to logging

ah yea thats early kernel stuff

[unreal bay]

Do you have CO2 sensors, and do they pickup them discharging extinguishers?

[glad mortar]

but yea typically you get a timestamp and the subsys logged per line

maybe add a LOG_INF to your main

just to check it works

oh that looks better

hm yea maybe increase your log buffer too then

not sure why its still dropping

[timid plover]

we saw "inf" and "<dbg>" is <dbg> a subsystem name ?

or a log level ?

[glad mortar]

yea dbg is debug log level

[timid plover]

maybe net_mgmt: is a subsystem then ?

[gusty wedge]

Yeah, cause you also have <err>

[glad mortar]

yea

[timid plover]

is spi_nrfx_spim the communication between the two chips ?

[glad mortar]

spim is the nRF spi peripheral

[unreal bay]

Need a slight angle change and a window sticker for Dragon Cam

[glad mortar]

its saying "adding interface" from the nRF driver right before, maybe that did not finish before you make the call?

[timid plover]

at least the breaze is away from your window 🙂

so some early initializers are already trying to bring the if ?

[glad mortar]

I would double check that the line that errors out is not making assumptions, sounds suspicious that the driver was adding the interface right before and then the network manager complains that the request times out, might just be going to nowhere

yea thats what I meant, the onboard jlink can do rtt logging, then you can see Zephyr verbose logs there and are not cluttering your logs

on zephyr side is just a kconfig for the rtt logger backend and to read it there are a couple different cli tools, jlink has the rtt viewer tool

its essentially your auth to the AP, its where you provide your key n stuff

but is a bit weird that that would log such low level error about the interface

but I have done extremly little wifi stuff with Zephyr so far

btw does the wifi shell sample work on its own as expected? If you haven't tried it I would maybe compile that with your current settings to make sure its not a configuration thing or wrong board target

[old surge]

(I despise articles like that: "WPA is the WPA that handles WPA on behalf of WPA..." If I'm looking at (especially) Wikipedia, unpack the acronym in sentence one)

[glad mortar]

I think the issue you have is pretty much on the zephyr side, not nordic specific

[nova totem]

Technical writing 101 (or even writing). If you define a word you don't use it to explain

[glad mortar]

then maybe track back from there what you do differently than the shell code

I would do a little hello world wifi thing that only does an init and scan in one function and not call the cpy stuff, just to make sure the assumptions of what the order of operation is is correct

[timid plover]

I wonder if similar logging was added to both shell and CP ? -

it was amazingly quick to get a response from the wifi shell !

[glad mortar]

yea its like a pop quiz but code 😄

wdym bringing it up yourself?

generally no, you should never interact with a device directly if you are interacting with a subsys

[timid plover]

perhaps you could discuss the software architecture

• and compare if you were to add CP to the shell
  vs.
  what I think you did - add zephyr to CP ? ( not sure if that's what you dod 🙂 )

[glad mortar]

the way Zephyr uses the term shell here means more a shell program, its a little helper that gives you new commands to the overall Zephyr shell

you would have to wait for the event to fire

so in the event callback "if event == the thing: do the next step"

yea thats why I would maybe try to replicate that basic function that the wifi shell utility implements just to make sure things are sound and then see what differes in your order of operation

oh and that is also odd, I never ever had to set that env variable 😄

did you run the setup script in the sdk?

which might be deprecated I think west might be doing it these days

ohno I mean in mainline zephyr

they have this script that setups the zephyr environment globally

yea it sets up all the paths that west would be looking for

yea there is an event

what its called in this case no idea 😄

so apparently you can grab a wifi interface and then register a wifi ready callback

oh wait might be an nrf library

hm yea looks like a helper library provided by nordic

so wpa supplicant has its own events, looks like you need to register for them

net_mgmt_init_event_callback(&net_wpa_supp_cb,
wpa_supp_event_handler, WPA_SUPP_EVENTS);
net_mgmt_add_event_callback(&net_wpa_supp_cb);

net_wpa_supp_cb being your cb function

yes sorry, the callback object

oh what did you change?

NET_EVENT_SUPPLICANT_READY and NET_EVENT_SUPPLICANT_NOT_READY is the actual event name to listen to

that tells you if the interface is up

afaik

do you actually wait for the scan done event?

ooh yea that would explain it

if you query it if its still in progress I would expect a hard error somewhere

yea 🙂

the net manager is fully event driven, need to be dilligent and only act on things when it fired the event that allows you to do that

so no synchronous logic possible

Zephyr has a lot of great primitives that you could maybe just wrap around

a lot of them handle locking internally so less stuff to think about

if you want to use Zephyr work queue without manual locking you could have a single thread be the owner of the queue to handle adding and dispatching work and have work come in and go out via a mailbox or zbus

ah actually I think work queue was thread safe, just need to make sure the data you put into it is also, otherwise you need to lock it to not delete it while in use

[gusty wedge]

"band" in wireless, is just how wide is the bandwith of a all of the channels.
