lorawan problem

Hi, i have an issue.
While connecting to the lorawan network (868eu), i didn’t know to generate the APPEUI and APPKEY and connect to the gateway. (only have the deveui)
I am using Heltec ESP32 v2 (sx1276 lora) board with the stock library.
Any recommendations about the library or an alternative solution.

You need to set APPEUI and APPKEY in lorawan server.
