LoRa TX function does not trigger IRQ on SX1276 (B-L072Z_LRWAN1)

AComa.170

Hello,

I'm developing an application based on B-L072Z_LRWAN1 hardware.

If i Program my code on the evaluation board everyting works good. I can send and receive packets with LoRa.

If I program it on my custom hardware (based on the evaluation board) everything works BUT the LoRa transmission.

I cant receive anything and the Tx function timeout ALWAYS expires.

Is there some activation procedure that has to be done to make the LoRa module work?

Thank You so much.

Andrea
