摘要
4G是目前广泛应用的无线传输技术,由于其稳定、时延低、覆盖范围广并且传输速率快的特点,在物联网领域中充当网关的角色,在数据传输量大、网络实时性要求高的物联网场景发挥着重要作用。文章主要阐述了4G模块如何采用TCP的方式通过MQTT协议实现消息远程传输的原理,介绍了STM32嵌入式系统与4G模块的开发设计、调试过程,实现了对4G通信协议的解析和信息传输与显示。
4G is a widely used wireless transmission technology,because of its stable,low latency,wide coverage and fast transmission rate characteristics,in the field of internet of things as a gateway,in the data transmission volume,network real-time requirements of the internet of things scenario plays an important role.This paper mainly expounds how the 4G module can realize the principle of remote transmission of messages by MQTT protocol by TCP,introduces the development design and debugging process of STM32 embedded system and 4G module,and realizes the analysis and information transmission and display of 4G communication protocol.
