Can't get RX to bind, WIFI stopps when trying to connect

[tropic socket]

Hi there
I just flashed the TX & RX to the same ELRS version & the same binding phrase & now I can't get my rx to bind.
RX: Betafpv ELRS nano RX

I double-checked, that the ELRS RX and TX got the same version and binding phrase, but it still doesn't work.

TX: Betafpv ELRS 1000mW TX Micro
FC: Rush 3030
Betaflight Version: 4.4.1
ELRS Version: 3.2.1

[sudden brook]

put both tx and rx into wifi mode and post screenshots of their webui Options tab

[tropic socket]

oh sorry, forgot to mention that
as soon as I try to get into wifi mode it goes back to " Slow blink 500ms on/off Waiting for connection from transmitter" LED indicator and no website opens

[sudden brook]

how is the receiver being powered up?

[tropic socket]

by the FC through USB (tried powering the fc with a lipo, same issue)

[sudden brook]

reflash the receiver via passthrough..

[tropic socket]

I did, that's the log

[sudden brook]

can you post a photo of the receiver?

[tropic socket]

build into the quad? or just the type of the rx?

the wiring has to be correct, since it's been working on a previous version and I have not changed anything hardware wise

if the wiring would be wrong, I couldn't flash it, right

[sudden brook]

which exact receiver do you have? could you post a photo so I can confirm that it should use the Nano target or not..

this one

[sudden brook]

can you post an actual photo though?

[tropic socket]

oh wait it still doesn't connect to the tx, but I can now open the website

will send you the 2 screenshots of it

Ok, the website only open after flashing, after that all I get is this

[sudden brook]

that's not the webUI though

[tropic socket]

Thats the package of it

kinda difficult to get a picture of the rx built inside

[tropic socket]

yea I know 😄

@sudden brook

[sudden brook]

wifi connection is flaky..

there SHOULD be something on those options

[tropic socket]

yea, that's right after the re-flasing though (without a power cycle)

I can't get to connect to the wifi after one power cycle, it shows up and redirects me to the 10.0.0.1 adress, but right after connecting to it it goes back to " Slow blink 500ms on/off Waiting for connection from transmitter"

[sudden brook]

reflash the receiver via UART/FTDI adapter.. perhaps use the web flasher so you have the option of erasing Flash First..

https://pkendall64.github.io/elrs-web-flasher/

[tropic socket]

I don't have that adapter..

or do you mean wifi flashing?

[sudden brook]

no..

else I would've typed that..

[tropic socket]

just making sure 🙂

[sudden brook]

your other option would be to connect a different ELRS receiver altogether

[tropic socket]

attention, kinda loud
but thats the blinking I get after I powercycled it and tried to open the website

the blinking at the beginning lasts about 10-20s (in the video only a few seconds due to file size on dc)

[sudden brook]

because that's what you set your auto-wifi on interval..

and it also appears it connects to your local wifi network..

[tropic socket]

yea, makes sense

[tropic socket]

it can't, it's not there (it's a hotspot from my phone, and I have not activated it)

[sudden brook]

and when you connect through your phone, it would restart with slow blink?

[tropic socket]

yea, after power cycle it opens the hotspot -> I connect to it -> it tells me to open the website -> I open the website (do nothing else) -> it closes the hotspot -> starts blinking slower -> after a while it starts blinking fast again and opens the hotpost -> repeat

[sudden brook]

reflash the receiver to 3.0.0, unless you've already tried..

else I would suggest disconnecting the receiver from the FC, and get a uart-adapter so you can reflash through that..

[tropic socket]

before I try that I tried to connect via the home wifi
this is what I got:

[sudden brook]

could you connect to the TX module/radio webUI this time and post the same webUI Options tab please..

the UID numbers of receiver and TX module should be the same.. for there to be a bind.. whether it's manual binding or via a binding phrase

[tropic socket]

what's the URL to that one?
http://elrs_tx.local didn't work

[sudden brook]

does it connect to your local wifi network though?

[tropic socket]

oh sorry, stupid me

sooo the UUID clearly doesn't match

BUT

in the log when flashing the TX module it shows:
`Processing BETAFPV_2400_TX_MICRO_1000mw_via_UART (platform: [email protected]; board: esp32dev; framework: arduino)

Verbose mode can be enabled via -v, --verbose option
UID bytes: 75,103,65,19,103,191

---

Building for ESP32 Platform`

so something went wrong when flashing?

@sudden brook

[sudden brook]

seems the wifi connection is flaky..

might not even be what's on the actual module..

refresh the tx webUI..

those other fields should have values on them.. and the target should be visible in the banner

[tropic socket]

you mean reflash the whole TX?
that's what I just did
how could I reflash just the webUI?

something in the flashing log I found, no idea if that's normal

[sudden brook]

refresh/reload the webUI page

press the F5 key

[tropic socket]

but that's totally not what I've flashed 😄 (UUID, Wifi auto on, TLM)

[tropic socket]

can I just edit the settings in the web UI and not worry about it?
It's kinda strange that it flashed the new firmware (3.2.1), but not the settings

[sudden brook]

then just change those values on the webui

set TLM report interval to default 240 value

[tropic socket]

will it generate the same UI when I put the same binding phrase?

[sudden brook]

it should

[tropic socket]

okey good, I'lll just do the same as here (RX)
