I am trying to send a Tx by publishing to an MQTT with my Protobuf DownlinkFrame message. The gateway bridge claims it has in an invalid gateway_id, as it appears to be all zeroes. I have encoded my gateway_id as base64 in the protobuf message, however, and don’t know what is going wrong.
Here is the error from the gateway bridge:
INFO integration/mqtt: downlink frame received downlink_id=85506f95-0e60-4134-a4de-3d9e148a8e17 gateway_id=0000000000000000
ERRO send downlink frame error error=“get gateway error: gateway does not exist”
The protobuf message (not serialised) is this, which clearly has a gateway_id set at the end:
Any advice or help would be much appreciated, as this is stopping me from sending downlinks. Thank you.
