Problem with sending downlink via MQTT



I have loraserver up an running (GW bridge, loraserver and lora appserver on one physical host). I can see Uplink and downlink in appserver GUI - all looks working fine.

I need to send downlink manually via mosquitto_pub command.
I found several threads already on similar topics, but I think my issue is simpler, I’m missing something.

I am publishing as:

mosquitto_pub -t “application/1/#” -m “hello world” -u {loraserver mqtt username} -P {loraserver mqtt pwd}

also tried particular node:

mosquitto_pub -t “application/1/device/333934376c356214/tx” -u {loraserver mqtt username} -P {loraserver mqtt pwd}

publish output:

Client mosqpub/25000-vps590769 sending CONNECT
Client mosqpub/25000-vps590769 received CONNACK
Client mosqpub/25000-vps590769 sending PUBLISH (d0, q0, r1, m1, ‘application/1/device/333934376c356214/tx’, … (2 bytes))
Client mosqpub/25000-vps590769 sending DISCONNECT

and then listening on:

mosquitto_sub -v -t “application/+/device/+/+” -u {loraserver mqtt username} -P {loraserver mqtt pwd} --debug

subscribe output below, but nothing else.

Client mosqsub/29322-vps590769 sending CONNECT
Client mosqsub/29322-vps590769 received CONNACK
Client mosqsub/29322-vps590769 sending SUBSCRIBE (Mid: 1, Topic: application/1/#, QoS: 0)
Client mosqsub/29322-vps590769 received SUBACK

I’m watching the journalctl in paralel for Bridge, loraserver and lora app server, but all I see is the normal messages sent by the node uplink/downlink.

mosquitto client seems to work fine also, as I can subscribe for the gateway topics and I can see the packets arriving from the node.

mosquitto_sub -t “gateway/#” -v -u {loraserver mqtt username} -P {loraserver mqtt pwd}

I would appreciate if anyone can point at the problem, I can send the logs is necessary.

thanks in advance,
