nRF52832添加微信硬件接入服务AirSync
开发环境
SDK版本：nRF5_SDK_15.0.0
芯片：nRF52832-QFAA
OS: FreeRTOS 10.0.0
测试APP：AirSyncDebugger https://iot.weixin.qq.com/wiki/doc/blue/AirSyncDebugger2.3.0.apk
AirSync概述
AirSync是微信硬件平台提供的一种微信客户端与蓝牙设备间通讯的技术协议，它允许蓝牙设备与微信客户端之间收发数据，并支持通过微信客户端透传到远程服务器。该技术在支持微信互联的蓝牙手环、血压计、智能秤、血糖仪等设备上有比较多的应用。
详细开发文档请参考官网 微信硬件平台的
AirSync 服务添加
本文仅仅就怎么在sdk15的框架下添加 AirSync 服务进行描述，具体协议实现请参考官方给出的示例程序即可
ble_wechat_service.c
蓝牙设备需暴露两个特征值（Characteristics）：Write特征值，Indication特征值。蓝牙设备从Write特征值接受数据，从Indication特征值发送数据。
