Hi Everyone,
I'm trying to connect my Onion to a LoRa module.
This module uses Serial Port. I can't find any instruction about how to communicate with Serial Port, I tried to plug to TX & RX on the extension dock (still I don't understand why there is a + and - on it and not on the onion itself) and I tried to send message through /dev/ttyATH0
Have you ever use serial port to communicate with a module ?
Thank you for your help,
Dorian
