Guide to MQTT
An introductory guide to MQTT – the most used IoT messaging protocol
What is MQTT?
MQTT (Message Queuing Telemetry Transport) is a communication protocol for the Internet of Things (IoT) that uses the publish/subscribe method for communication. MQTT is lightweight and is used in low bandwidth environments.
The three main roles in MQTT are the Producer, the Broker, and the Consumer. The producer publishes a message to the Broker. The Broker sends the message to the appropriate consumer(s) that are subscribed to the specific topics.
Benefits of MQTT
An MQTT broker is responsible for sending messages from the producer to the consumer. The broker also queues messages for MQTT clients that are subscribed to various topics and sends specific messages to appropriate clients.
When starting with MQTT, it is important to start with a reliable and trusted MQTT broker. The Eclipse Mosquitto MQTT broker is the most popular MQTT broker in the world. It is written in C language which makes it extremely fast. Mosquitto is available in both open source and premium versions.
