检测数据上报
clien → server {"opcode":"reportedData","deviceId":"0001","temperature":20,"pm25":50,"humidity":50,"opticalInductor":50,"illuminatingBrightness":0,"latlng":"[23.1666981,113.429923]","bodyInductor":0,"smokeSensors":0}/n
协议含有相关字段则开启该功能
server→ clien {"opcode":"setIP","deviceId":"xxx"," IPAddress ":"192.168.1.68"," subnetMask":"255.255.255.0"," gateway":"192.168.1.1" }/n
UDP广播修改服务器地址
UDP订阅端口是：7776
