Now I got it to compile, but I am not being able to retrieve data from the i2c bus from the Arduino. I’m using this code https://github.com/cipiasentini/lorai2c/blob/master/mBed%20Firmware/mbed-os-example-lorawan/main.cpp the connection to the gateway is done, and dummy data is sent. But if I try to read from Arduino i2c I get nothing being sent. My Arduino sketch is here https://github.com/cipiasentini/lorai2c/blob/master/Arduino%20Sketch/nuevo_dht_simplificado_lora_i2c/nuevo_dht_simplificado_lora_i2c.ino
Did you manage to get something done on this? I’m facing the same problem. Forgive me, I know it’s an extremely old post.
