Why MQTT?

Lightweight and reliable

Compact MQTT packet, enable stable transmission over severely restricted device hardware and high-latency / low-bandwidth network.

Better ecology

Its client and SDK covers all language platforms, it is an Internet of things platform standard communication protocol for AWS IoT Core, Azure IoT Hub and other top cloud vendors, which is an actual standard of Internet of things.

Publish-subscribe model

Based on the publish-subscribe model. The advantage of the publish-subscribe model is the decoupling between the publisher and subscriber: there is no need to build the direct connection between the subscriber and publisher, nor need to on-line at the same time.

Born for the IoT

Provide comprehensive IoT application features such as Heartbeat mechanism, Will message, QoS quality level + offline message, asynchronous mechanism, topic and security management.

MQTT Beginner's Guide

What is the MQTT protocol →

MQTT is an IoT protocol based on the Pub/Sub model. With its characteristics of simple and easy implementation, support for QoS, and small packet.

Introduction to MQTT publish-subscribe model →

The core of MQTT is the publish-subscribe model. In this article, we will introduce this model in detail.

How to use MQTT packet to implement publish and subscribe →

The MQTT protocol communicates by exchanging predefined MQTT control packets. We will take MQTTX as an example to show how to implement the publish and subscribe function through MQTT packets.

Advanced features of MQTT topics →

MQTT will route messages based on topic. The broker will route messages to all the client that have subscribed to this message topic.

MQTT Session →

The messaging series start from initiating an MQTT connection request to the server until the connection is interrupted and the session expires is called session.

Introduction to MQTT QoS (Quality of Service) →

MQTT protocol specifies the 3 QoS (Quality of Service) levels, which guarantees the reliability of message delivery under different network environments.

Use of MQTT Will Message →

When the client disconnects, a will message is sent to the relevant subscriber.

MQTT Retain Message →

When MQTT clients publish messages, you can set the retained message flag, and then the next subscribers can receive the latest retained message when subscribe.
