All new nodes have set BR 11520 and the logger is working nicely, I finaly have a way to debug basic problems!

@sundberg84
So I tried all rx/tx combinations, no response to AT commands, I will try with different software and/or computer.

OK, couple of good pointers!

I found the atmega RX a TX pins, but cannot get any response in the serial console.

Connectiona are: USB -> USB Serial Converter -> GND, power -> logger & RT/TX -> Tx/RX on atmega on logger.

If I set BR to 11520, I can see on my BT connected phone what I typed in the arduino serial monitor, e.g. if I type "AT" in Arduino serial console with BR 115200 , I can see clear ascii text "AT" on my phone.

If i set BR to 9600 or 38400, I see just scrambled characters or nothing at all.

I tried to put some test serial.println with BR 11520 on new pro mini (3.3V, 8Mhz), when I discovered some interesting problems....
None of my serial/USB converters worked, I tried to guess BR etc. to no avail.
I tried to reupload bootloader with usbasp, with set BR, but could not get clear text serial output form my nodes.... After 5 diferent USB to serial adapters i tried to compile code with arduino IDE instead of platformio, voala, now I could send text from promini with BR 115200 through logger to my phone.

So there are couple problems, probably with my toolchain (platformio) - I remembered that I had problems with some new custom boards (NRF24Duino) and serial output which was garbled...

But nevertheless, I cannot change BR of logger, because I am using custom bootloaders with 1 MHz internal oscilator and 4800 BR, I need to set it lower.

What else could I try?

Hello Sandberg84, I recently bought the logger and have problem setting up baud rate.
I can connect to BT with my phone just fine, I can get serial output from sensor at specified intervals, but it is all nonprintable characters, alas bad baud rate.
When I connect logger to pc via serial adapter I get no response to AT commands.
Can you show me way to try something?

Thanx

What is the serial upload speed?

Ok so after further reading I found info on the issue, it seems that these are debug messages, we can safaly ignore them.

I have same problem, on both my GWs using MQTT (ESP2866 nodes ) in homeassistant i get lots of these errors

Hi, I placed an order with allpcb, but during review there was error no noc drill file, can samobody help me to generate them from brd file or is the file missing? Thanx for good board!

I would like to see panelized version for dirtypcb, someone?
