reCamera MQTT output not detected on commandline

[tonyreina]

I have a reCamera connected to an NVidia Orin AGX. I am using the default Node RED application that runs Yolo to detect people. I am able to add a MQTT out node and pass messages that are visible in a MQTT input node on the same Node RED graph, but if I run mosquitto_sub -t '#' -v then I don't see the messages.

How can I see the messages from the commandline?

There are some errors in your command. Firstly, the Mosquitto service in the recamera has already been started. You can start the service and view the relevant information by using the command cd /etc/mosquitto/ && mosquitto -c mosquitto.conf -v. If you want to subscribe to a topic using the Mosquitto command, use the mosquitto -t "topic" command. If you want to send relevant information, use the mosquitto -t "topic" -m "message" command. And do not use mosquitto -t "#" to subscribe to all topic messages, as the data volume will be very large, and this is not recommended.
