[原创] 【LinkNode D1开发板】LinkNode D1连接贝壳联网传输数据

tianlai-1033994

           LinkNode D1连接贝壳联网传输数据已经实现了，之前的时候测试了开发板和LINKSPRITE IO平台的联网，功能倒是实现了，不过满屏的E文还是不习惯。于是转到贝壳，注册账号测试了下，感觉还是很不错，这里跟大家分享下。
        我选的是BMP180模块，传输气压，温度和海拔的数据，地址在   http://www.bigiot.net/chart/836.html，具体的功能可以看看，以下是图片：

   测试了段时间，感觉还是比较稳定的。
  以下是整体代码：
