Starting with Firmware 0.5.0, the default values for JoinEUI (aka AppEUI), AppKey, and NwkKey in the configuration have changed. Be sure to check your LoRaWAN-Configuration between device and Network Server, after you update to this version.

You can adjust those values to your need with our config adapter.
