1.zigbee编写语言为C语言，使用ZStack-CC2530-2.3.1-1.4.0协议栈；
2.APP使用eclipse eda安卓开发，采用sim900A连接外网，可简单修改连接esp8266wifi模块，从而连接外网，app能够实时显示采集zigbee采集的距离；
3.服务api采用的是淘宝云平台的api，服务器长期有效，无需修改；
4.通过cc2530之间通信，采集到rssi值，计算出距离，通过串口上传上位机，该程序能简单修改主函数，实现测距。(1.zigbee is written as a C language, using the ZStack-CC2530-2.3.1-1.4.0 protocol stack;
2.APP is developed by eclipse EDA, Android, and sim900A is connected to the external network. It can simply modify the esp8266wifi module to connect to the external network, and app can display the distance collected by ZigBee in real time.
3. service API uses the API of Taobao cloud platform, the server is effective for a long time without modification.
4., the program collects the RSSI value through the communication between CC2530, calculates the distance, and uploads the host computer through the serial port. The program can simply modify the main function and realize the ranging.)
