Hi there, I have a Chirpstack Network Server installed on Ubuntu Linux and a connected and configured Lora Gateway., it is not receiving tag frames.
ChirpStack log-output:
ERROR chirpstack::uplink: Deduplication error error=Log uplink for gateways: An error was signalled by the server - ResponseError: unknown command ‘XADD’
Deduplication error means multiple gateways received the same frame fcnt or the device has not incremented the fcnt for a new packet.
Deduplication is done with Redis. The error message might be indicating that XADD is not supported by your version of Redis. The documentation says that this command is supported from 5.0 onwards.
