STM32F411 and P-NUCLEO-LRWAN1 (SX1272MB2DAS)

[Larraitz]

Hi,

I'm trying to run ping pong example in f411 board with sx12mb2das module but it doens't work and I don't know why (I have b-l072z-lrwan running as receptor). Has anybody ran the program in that board?

Thank you.

Make sure both are built with the exact same frequency bands and radio settings. Print them out a debug port to be sure.

I've used the SX1272MB2DAS radio boards on all manner of STM32 F4, F7, L0 and L4 DISCO/NUCLEO boards.

They are running with the exact frequency band and radio settings... any other idea?

Enable the debug messages. Create forks where one always transmits and the other always receives. Try to determine if the issue is primarily Tx or Rx related. Inspect the radio registers, check interrupts occurring.

Radio is a fickle medium, it takes effort to debug/diagnose.

I have seen that the program never enters to RX or TX state and always stays in Lowpower state doing nothing. Could be that I have something deactivated and that's why it doesn't transmit anything?
