Checked out your sketch for the esp32s3 and used SX1262 radio = new Module(/NSS/D4, /DIO1/D1, /NRST/D2, /BUSY/D3); and the radio initilises. Ping pong example works fine. The LoRaWAN example for connecting to the TTN refuses to join which doesn’t surprise me as I always have trouble with the AUD915 Suband 2 setting in libraries I’ve tried.
Thanks for you help guys and nudging me in the right direction. Will continue to tweak the code.
Cheers Dave
