Received JoinAccept with major:"Major(1)"

Hi @brocaar ,

We have installed one gateway in the middle of the city and we are receiving traffic on our gateway.

  • We have installed 2 Devices and both devices are sending packets through our installed gateway and it’s working fine.

Sometimes we are receiving JoinAccept on Gateway Live LoRaWAN Frames with major: "Major(1)" please see below screenshot for your reference.
Currently, our devices are joined and not sending any join request we are receiving JoinRequest from other third-party devices but why Gateway shows the JoinAccept frame? as I have checked server logs but not found any downlink/JoinAccept.

Also, we receive JoinAccept in the UPLINK frame. see above screenshot…

Received JoinAccept in Uplink frame


Please note that your gateways can receive data from other devices too. Potentially the above could be a non LoRaWAN (compliant) device that is picked up by your gateway?

Hi Brocaar,

Thanks for the update.
