ESP32 LoRaWAN Node and TTN Keys

thermalmatters · July 21, 2021, 3:30pm

I’ve managed to connect my devices using ABP and the sample code but am getting very confused (newbie) with the OTAA keys. I have found the licence keys but the ttn-otaa-sleep example wants appkey, which I have, but where do I find the devEUI and appEUI? I’m looking through the documentation but going round in circles

At the beginning of the program, you can see DevEui, AppEui, AppKey and other parameters.
