With the provided information, it looks like the gateway did accept the downlink for transmission, given there is a JoinAccept message. It is hard to provide you with more help. Possible scenarios that I can think of:

  • The gateway accepted the downlink, but was unable to transmit it (check the gateway logs)
  • The gateway did send the join-accept, but it was not received by the device (antenna issue?)
  • The gateway did send the join-accept, but the device was (for whatever reason) unable to handle it (firmware issue?)
  • The device was activated, but for some reason is constantly resetting (firmware issue?)

Things you could try:

  • Test with a different device
  • Use a spectrum scanner to verify if the gateway is sending the join-accept

Here is the log from the device. Could it be that chirpstack does not send back devaddr, NwkSKey, AppSKey info?
