LoRaWAN Join fails

To find the reason for a missing / failing Join Request check the following information:

  • What LNS is used?
  • Is the device registered with the correct LoRaWAN Version (mostly 1.0.2 for Lobaro Devices)
  • Is the device configured to use LoRaWAN v1.0 (v1.1 use should be avoided since it's not certified)
  • Are all Device parameters correct in the LNS: DevEUI, JoinEUI (aka AppEUI), AppKey
  • Is there a possibility to trace the Join request on LoRaWAN Gateway Level?
  • Does the Server states any Errors when receiving the Join Request
  • Is there any error indication inside the device log?
    • e.g. "hw error for tx data up"
