I have LoRaWAN network based on RAK7268C and AWS IoT Core LoRaWAN server. Gateway is connected by Ethernet cable. For some time I’m struggling with 2 problems:
- sometimes I don’t receive ACK response frame for Downlink Confirmed message. My device is resending that message with 2 minute interval, but sometimes I receive ACK response after at least 3-4 tries. I checked LoRa Packet logger to be sure that ACK frame wasn’t transmited.
- sometimes I don’t receive Join Response after Join Request message. Usually I have to send at least 2 Join Requests and after second message I got Join Response. Worst case I’ve seen was when device was trying to connect for over 4 hours. In this scenario I was also checking LoRa Packet logger in Gateway’s administration panel.
I’ve checked system’s log and there is something strenge. Every time ACK response is missing there are 2 warnings marked on screen:
Thu Oct 19 10:30:54 2023 user.warn basicstation: [S2E:WARN] Unknown field in dnmsg - ignored: regionid
Thu Oct 19 10:30:54 2023 user.warn basicstation: [S2E:WARN] ::0 diid=13472 [ant#0] - unable to place frame
Any ideas if these warning are related with my problem?
