1. What is MQTT? MQTT, short for Message Queuing Telemetry Transport, is a lightweight protocol designed specifically for devices with unstable networks and limited bandwidth. For example, in Northeast China, there are times when the signal is poor, making it difficult to access the internet on mobile phones. This is when MQTT comes into play. … Read more
To pass the time, I will provide a detailed explanation of the MQTT protocol code implementation I wrote earlier; the main content will analyze and implement the MQTT network communication protocol, specifically involving the processing of network data stream segmentation. Therefore, much of the content will involve specific code functionalities. If you are interested in … Read more
MQTT (Message Queuing Telemetry Transport) and EMQX are two widely used communication technologies in the Internet of Things (IoT) and messaging systems. Although both are used for real-time communication and data transmission, there are some notable differences in their design, functionality, and features. This article will detail the differences between MQTT and EMQX, including protocol … Read more
MQTT: IoT Device Communication Protocol Stack Around us, more and more smart devices are quietly changing our lives. Have you ever wondered what happens behind the scenes when you use a mobile app to turn on the smart bulb at home? Today, let’s explore the “delivery guy” of communication between IoT devices – the MQTT … Read more
