ESP8266MQTTAT指令集主要包括以下几个指令：
1. 设置ESP8266工作模式: AT+CWMODE=1
2. 连接WiFi: AT+CWJAP="wifi","password"
3. 设置本机信息: AT+MQTTCFG=0,1,"id","user","password",0,0,""
4. 连接MQTT服务器: AT+MQTTCONN=0,"IP",1883,0
5. 订阅主题: AT+MQTTSUB=0,"test",1
6. 发送消息: AT+MQTTPUB=0,"test","1",0,0

这些指令可以用于配置ESP8266的工作模式、连接WiFi、设置MQTT服务器等相关功能。其中，+CWMODE指令用于设置工作模式，+CWJAP指令用于连接WiFi，+MQTTCFG指令用于设置本机信息，+MQTTCONN指令用于连接MQTT服务器，+MQTTSUB指令用于订阅主题，+MQTTPUB指令用于发送消息。请注意，不同的AT固件版本可能存在差异，以上是基于安信可官方提供的MQTT透传AT固件(固件号: 1471)给出的指令集。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
