I am having difficulty with MQTT Publish on TTN V3.
I have successfully managed to subscribe to the uplink and can read data etc.
Using topic: “v3/light-relay@ttn/devices/eui-70b3d58ff102165a/up”
However, when I try to publish a command, this is not seen in the Live data on TTN.
I am publishing the command:
{"downlinks”: [{"f_port”: 2,"frm_payload”: “BAABAAAAAAAAAA==”,"priority”: “NORMAL”}]}
To Topic:
“v3/light-relay@ttn/devices/eui-70b3d58ff102165a/down/push”
(I have tried with @TTN and without @TTN. This made no difference.)
My MQTT Broker does not return any error, and the application confirms connection when I connect.
I have tried on port 1883, and 8883 TLS enabled and disabled.
MQTTFX broker log message:
2021-10-23 09:25:26,996 INFO — PublishController : publish

However, when I send the same message to port 2 from the console, the message is received.
Any ideas on why this is happening.
