Chirpstack v4 is nearly released, and we are eager to move to it for it’s enhanced feature set.
Unfortunately, some (perhaps just the down link command) of the MQTT Protobuf definitions have changed, and the built-in gateway bridge is not compatible. The changes, from what I can tell, are mostly a reorganization of the parameters. You can find the new definitions here: https://github.com/chirpstack/chirpstack/blob/master/api/proto/gw/gw.proto)
Chirpstack’s own gateway bridge was made to be backwards compatible.
Are there plans to support Chirpstack v4 with the RAK7289?
We have the same issue.
I was starting to deploy a new instance of out production server and faced this issue. We have 50 gateways so it is a big deal, there are some new features in Chirpstack V4 that we really need.
Thanks in advance!
