在前面的博文中,博哥介绍了 PubSubClient 这个使用率很高的Arduino MQTT库,具体可以参考 玩转PubSubClient MQTT库。 然而,博哥这里重点讲解另一款使用率也非常高的Arduino MQTT库 —— Adafruit_MQTT。 当然,博哥这里不会重点讲解MQTT协议(毕竟以前的博文已经花了很大篇幅讲解),需要了解的同学请仔细阅读 玩转PubSubC...

1.使用的mqtt arduino 客户端是 pubsubclient 库。其默认是ESP8266, 所以例子例包换文件“Wifi8266.h”,可以改为"Wifi.h"就可以。 2.关键是按照mqtt的onenet文档,编制payload数据包。其具体格式有多种类型。调试的是最简单的type3, json数据2 形式。 /* Basic ESP8266 MQTT example This sketch demonstrates t...

MQTT协议(Message Queuing Telemetry Transport),翻译过来就是遥信消息队列传输,是IBM公司于1999年提出的,现在最新版本是3.1.1。MQTT是一个基于TCP的发布订阅协议,设计的初始目的是为了极有限的内存设备和网络带宽很低的网络不可靠的通信,非常适合物联网通信。 MQTT属于应用层协议,基于TC...
