E220 LoRa device: how to make 3 devices communicate together
Hello, I bought 2 E220-900T30D modules and after two days I can't just display a message! I use the tutorial on this page with the code from the library. When a module sends a message the led of the other arduino nano flashes
As the two LEDs of the two modules flash together I imagine that a transmission is well done.
but no message on the terminal! I just want to communicate 3 modules together and it looks way too complicated with your library! But I can't find anything else...
