Raspberry Pi


Setting up an MQTT broker on Raspberry Pi. This is an introduction article and a basic configuration guide. As the Mosquitto Broker is basically synonymous with MQTT on the Raspberry Pi, we will focus on this tool in relation to MQTT (there are of course more).


MQTT, short for Message Queue Telemetry Transport, is a light weight messaging protocol that enables embedded devices with limited resources to perform asynchronous communication on a constrained network.

Developed by IBM and Eurotech, the MQTT protocol is released as an open standard and being standardized by OASIS (Organization for the Advancement of Structured Information Standard), a non-profit consortium that drives the development, convergence and adoption of open standards for the global information society.

MQTT on the network

In general, the MQTT environment consists of multiple clients and a server, called broker.


Mosquitto is an open source (BSD licensed) message broker that implements the MQ Telemetry Transport protocol versions 3.1 and 3.1.1. MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "machine to machine" messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers like the Arduino.

Mosquitto Debian Repository

There are many guides urging you to install from source. This obviously is always a good idea, but we will be using istead a Mosquitto Debian Repository. It has been recently made available and it does provide the latest version of Mosquitto to Raspbian, instead of the stale versions before. It is a simple process to attach it.

To install MQTT on your Raspberry Pi, follow our tutorials found in our project IoT Raspberry Pi Device, specifically on the Mosquitto on Raspberry Pi page.
