RE: MQTT Client app - jmir - 13.06.2025

Hi,

I've seen that topics beginning with $ are system topics.

Is it a restriction in the topic input box? Because I've tryed using Mqtt-Explorer and I can use $ in topics.

Thanks

Hello Team:

I have two LM one as broker MQTT and the other running MQTT Client app, everything is fine, very thing is running very well, ... but, until I tried to publish addresss 50/1/12 Out(To MQTT) with topic "topic_out/temperatura" and subscribe to that same topic "topic_out/temperatura" in the same LogicMachine Broker to recive the message in adress 50/1/13 In(From MQTT).
As you can see in the Next screenshot.

   

The problem is that when I write in address 50/1/12 other subscriptors to the Topic ("topic_out/temperatura") receive the message but not the own Topic "topic_out/temperatura" than I subscribed in the same LogicMachine Broker.
I want to know if it's a bug, or I cant not publish in the broker that I want subscribe with the same Topic.

Thank you very much,
best regards
Roger

This is done to prevent message loops. MQTT client app subscribes to all topic with "no local" flag enabled (bit 2: https://docs.oasis-open.org/mqtt/mqtt/v5.0/os/mqtt-v5.0-os.html#_Toc3901169).
