I think I face exactly this problem join request after join request without sending any data…
Using mcci-catena/MCCI LoRaWAN LMIC library@^3.3.0
and the second problem is as I don’t know if I have a SX127x or a SX1262 LoRa module on my T-Beam module … don’t know how to find out. There is nothing written on the chip.
Is seems as there is no way “at the moment” to make a SX1262 work …
… does someone have a working example for the ESP32 and SX12xx ? to learn how to communicate with ttn.
