Lora Basics Modem on STM32L073RZT6

[Julio_Ferreira]

Hello,

I'm working on testing the LoRa Basics Modem V4,
available in SWL2001 on github, and for now I've managed to generate the executable
and download the program on the board I have, but nothing has appeared yet on The Things Network.
I believe the key [ USER_LORAWAN_GEN_APP_KEY ] is not configured correctly in my project and
I have not found anything that references it,
does anyone know what the equivalent of this key is in TTN?

My hardware:
STM32L073RZT6
SX1272MB2xAS

Hello @Julio_Ferreira and welcome to the ST Community :smiling_face_with_smiling_eyes:.

I suggest you follow this video. It should help you to understand how it works. For the example you are using, it is not an ST Official example. So, I have no idea about it. 

Best Regards.

Hello @STTwo-32, thanks for the answer. But I already did this test at another time and it worked perfectly. 
What I'm trying now is to do a "hello world" by implementing Relay
