一个安卓端app，接收服务器发送的upd控制指令，连接meizu蓝牙红外遥控器，并将反馈的数据通过udp反馈给服务器进行处理。

代码基于FastBLE,增加了udp数据通信功能。

目前基本实现了电池电压、温湿度数据采集和红外发射功能。
软件默认参数：远端udp服务器ip地址：192.168.2.33；服务器监听udp端口号：8086；本机监听udp端口号：8087。参数按实际情况修改。
读电压、温湿度数据udp包数据格式：meizu蓝牙地址+空格+读指令；返回udp数据包格式：meizu蓝牙地址+空格+返回数据；
电压读指令：55030110(16进制)；返回数据：55040110xx(16进制)
温湿度读指令：55030111(16进制)；返回数据：55070111xxxxxxxx(16进制)
红外发射udp包数据格式：meizu蓝牙地址+空格+写指令；返回udp数据包格式：meizu蓝牙地址+空格+返回数据；
红外指令格式：550c0103xxxxxxxxxxxxxxxxxx(16进制),xxxxxxxxxxxxxx码通过log文件获取；发送成功返回数据：5504010401；不成功返回数据：5504010400
udp指令发送和反馈数据处理可以在node-red中进行处理。
node-red自己用的流以供参考，修改对应的蓝牙地址、udp参数和红外指令:
