Unused pins

[kauly]

In the board_config.py, how we define unused pins? Getting always this AssertionError and I think it's because bad board configuration. I using the NiceRF LoRa1276 and a rasp zero w.

/home/pi/lora-testes/LoRaWAN/SX127x/board_config.py:51: RuntimeWarning: This channel is already in use, continuing anyway.  Use GPIO.setwarnings(False) to disable warnings.
  GPIO.setup(BOARD.LED, GPIO.OUT)

any solution for this please?

The python lib SX127x uses 4 DIO hardcoded and there functions are:
DIO0 00: RxDone
DIO0 01: TxDone
DIO0 10: CadDone
DIO1 00: RxTimeout
DIO1 01: FhssChangeChannel
DIO1 10: CadDetected
DIO2 00: FhssChangeChannel
DIO2 01: FhssChangeChannel
DIO2 10: FhssChangeChannel
DIO3 00: CadDone
DIO3 01: ValidHeader
DIO3 10: PayloadCrcError

Maybe you can check which functions are missing since the NiceRF chip has only 3 DIO, my guess is DIO2 so you could hack out all DIO2 functions and make sure DIO0, DIO1 and DIO3 are connected.

I have the same error with Raspberry Pi B+ and all the pins are connected.

I am getting the same AssertionError because self.mode = 0. This is with a Dragino Hat on top of a Pi 3.

Has anyone been able to resolve this issue?

Thanks in advance!
