Zombie serial comms

Post by et0 »

I previously managed to send out some bytes on the UART3 (that is normally used for the wifi module) to try to trace and debug the code.

But in recent versions, I find I can't even read the normal data output to the module. This should be 115200 baud, 8N1, 3.3V levels.. Switching back to an older binary I can read this 100% fine without errors, so I don't think it's a problem with the FTDI cable, although I have tried different ones, different laptop and slightly different receive baud rates etc.

It's a head scratcher. Does anyone know of a change in the project that could cause this, clock speeds or UART configuration or something? The wifi GUI still works, to be clear.

From the wiki
"If you're having trouble connecting using the serial interface, note that the parameters are 115200 8-N-2, which is different from the conventional 115200 8-N-1. "

Thanks very much, weird that it changed, and to such an "unusual" configuration!
