【IOT】小项目2贝壳物联

1.获取www.bigiot.net的ip 121.42.180.30

2.创建一个智能设备

记住 ID：11374 APIKEY ：65ab1c85b 通过贝壳物联平台通讯协议 https://www.bigiot.net/help/1.html 设备登录 （加密） 别忘了\n {“M”:“checkin”,“ID”:“xx1”,“K”:“xx2”}\n {“M”:“checkin”,“ID”:“11374”,“K”:“65ab1c85b”}\n {“M”:“checkin”,“ID”:“11374”,“K”:“65ab1c85b”}\n {“M”:“say”,“ID”:“U8030”,“C”:“hello”,“SIGN”:“xx4”}\n

3.快速开始

测试：

如果 返回了 checkok才是连接成功 通过设备对话： PLAY 灯开

STOP灯关

点击 遥控设备

三角为PLAY 方块为STOP
