Hello,
I have bought 2 SPSGRF-868-Nucleo module. I want for beginning sent a packet for see how spirit1 works. But afters some search, I don't know if my packet is really sent or not because I receive anything.
I have configured 1 module for do a TX and other for RX.
TX seems work, because when I sent a packet the interrupt for TX data sent is SET.
For RX, I have no interrupt request for RX data available. Only discard.
This discard says that the RX timeout is done.
I have configured my module with this parameter :
