Hi,

I am trying to make this RIOT-OS example work on a TTGO Esp32. [RIOT/examples/gnrc\_lorawan at master · RIOT-OS/RIOT · GitHub](https://github.com/RIOT-OS/RIOT/tree/master/examples/gnrc_lorawan)  
The board uses a sx1276.  
So I need to register manualy the end device. My problem is to set correctly the following parameters on TTN :

Lorawan Version  
Regional parameters version

I am sure it is basic but I could’nt find the infos.

Regards  
Germain
