I need an example of communication with MQTT. Not only reading but also writing would be great!
I’ve uploaded an extended version of the example I sent you (plus, it uses only SELF.KOM for communication) at the end of our MQTT documentation

Data sent via one communication is received by the other one. The example works with a locally installed Mosquito broker (hence the local IP addresses)
I installed mosquitto, in the mosquitto.conf only added (or uncommented, I’m not sure) the line
listener 1883
and I run Mosquitto from the command line:
