## AT指令连接阿里云

1.  AT+RST
2.  AT+CWMODE=1
3.  AT+CWJAP="wifi","pwd"
    AT+CWJAP="Kong","123456789"
4.  AT+CIPSNTPCFG=1,8,"ntp1.aliyun.com"
5.  AT+MQTTUSERCFG=0,1,"NULL","{UserName}","{pwdword}",0,0,""	(mqtt连接参数里)
    AT+MQTTUSERCFG=0,1,"NULL","DeviceESP8266\&k18fnyx0PvT","1da3ef9276e611e6eea1e1d4e3376a723802247de8b3d579ece218807d5c507a",0,0,""
6.  AT+MQTTCLIENTID=0,"{clientId}"（at指令记得在逗号前加"\\"，如果在keil中需要加两个“逗号”）

    &#x20;AT+MQTTCLIENTID=0,"k18fnyx0PvT.DeviceESP8266|securemode=2,signmethod=hmacsha256,timestamp=1717403376231|"
7.  AT+MQTTCONN=0,"{mqttHostUrl}",1883,1	(mqtt连接参数里)
    AT+MQTTCONN=0,"iot-06z00ig0ugtcarx.mqtt.iothub.aliyuncs.com",1883,1
8.  AT+MQTTSUB=0,"/sys/k18fnyx0PvT/DeviceESP8266/thing/service/property/set",1
    (这个是物模型设备属性订阅的固定格式，在产品的topic列表中找)
9.  AT+MQTTPUB=0,"/sys/k18fnyx0PvT/DeviceESP8266/thing/event/property/post","{"params":{"Temp":20.2}}",1,0
    (这个是物模型设备属性上报的固定格式，在产品的topic列表中找,注意如果报“error”可能是需要取消勾选“转义符指令解析”)
    "AT+MQTTPUB=0,"/sys/k18fnyx0PvT/DeviceESP8266/thing/event/property/post","{\\"params\\":{\\"Temp\\":11.5}}",1,0","OK",50
