What is MQTT and what is it used for?

Message Queuing Telemetry Transport (MQTT) is a pure IoT protocol. It was designed in 1999 by Andy Stanford-Clark (IBM) and Arlen Nipper (Arcom, now Cirrus Link) specifically to address communication between machines - Machine to Machine (M2M).

You can find MQTT in a wide range of applications, such as industrial, health, logistics, mobile, connected cars, smart buildings, and smart cities.

MQTT is based on short messages with a publish-subscribe mechanism.

Let’s see some characteristics of MQTT:

  • Lightweight and bandwidth-efficient
  • Design adapted to constrained devices
  • Low power consumption
  • Data agnostic
  • Management of sessions
  • Quality of Service (QoS) implementation
  • SSL/TLS encryption
  • User and client ID management

The basic idea of MQTT is to exchange data between clients. Each client connects to a server running an MQTT service (broker).

A client can send data to the broker (publish...
