Manualy create end device parameters (Lorawan Version, Regional parameters version)


I am trying to make this RIOT-OS example work on a TTGO Esp32. RIOT/examples/gnrc_lorawan at master · RIOT-OS/RIOT · GitHub
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.
