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.
Thanks

You need to set APPEUI and APPKEY in lorawan server.
