Nowadays, the Internet of Things is more and more widely used, and MQTT, as a lightweight message transmission protocol, has gradually become one of the most popular protocols in the Internet of Things field. For the application of MQTT, we need an MQTT proxy server as the central hub for message delivery. This article will introduce some common MQTT proxy servers, such as Eclipse Mosquitto, EMQ X, and HiveMQ, and how to install and configure them on different platforms. We will also introduce in detail how to use these proxy servers to implement MQTT message transmission, including operations such as establishing connections, publishing and subscribing messages. If you are looking for an efficient and reliable MQTT messaging solution, then this article will provide you with valuable information.
1. Ready-made MQTT proxy server
When we want to use the MQTT protocol to implement message transmission, we can use a ready-made MQTT proxy server to simplify the development process instead of building our own MQTT proxy server from scratch. Common MQTT proxy servers include Eclipse Mosquitto, EMQ X, HiveMQ, etc.
1.Eclipse Mosquitto
Eclipse Mosquitto is an open source MQTT proxy server, written in C language, supports MQTT protocol versions 3.1 and 3.1.1, and also supports WebSocket and MQTT-SN protocols. It has the following characteristics:
- Advantages: Mosquitto is a lightweight MQTT proxy server that takes up less resources and is suitable for use in embedded systems or low-power devices. In addition, it supports SSL/TLS encryption, provides many configuration options, and is easy to deploy and manage. At the same time, Mosquitto also has an active community, which regularly releases updated versions, fixes known problems and adds new features.
