Mosquitto MQTT Setup for MorseLAB – Step-by-Step Guide (Linux) Raspberry Pi
MorseLAB - MQTT Server on RaspberryPi
In this video, I show how to install and configure an MQTT broker (Mosquitto) on Linux, specifically for the MorseLAB project.
This setup includes:
✔ installing Mosquitto
✔ configuring the listener on port 1883
✔ disabling anonymous access
✔ creating users and passwords
✔ setting correct file permissions
✔ starting and testing the broker
