微信官方对AirKiss有初步介绍，这个介绍中提到的库文件误导了我。事实上ESP的SDK_v1.2.0已经支持了AirKiss，我们只需要调用SmartConfig接口就可以了。
一个比较大的限制是，微信只将AirKiss的功能权限开放给企业服务号，而个人申请的订阅号则不能申请这个权限。不过微信还是给了
WeChat officials have an initial introduction of AirKiss the library file mentioned in the introduction misled me. In fact ESP SDK_v1.2.0 already support AirKiss, we only need to call SmartConfig interface on it.
A relatively large limitation is that WeChat only allows AirKiss access to the enterprise service number, while the individual's subscription number can not apply for this permission. However, weChat or gave DEMOto facilitate the debugging of developers. (2018-01-13, C/C++, 9177KB, 下载1次)

MS5基于STM32F103设计开发，可以在Keil下软件仿真调试，不需要实物硬件板子，UART1作为人机窗口。硬件测试是基于正点原子的miniSTM32F103RBT6板子测试，资料是开源的。MS5主要基于MS4（基于NXP Cortex M3）升级而来，因为在2011年基于MS4做了6KW高频焊接机，增加了界面部分，采用函数指针加消息机制，感觉比较简单而有效，性能比较不错，尤其是针对工业产品，系统节拍分时设计有进一步的体会，把这两点融入到MS5中，同时修改了串口UART发送系统等待问题，先把串口数据放到一个buff中，系统节拍去检测buff，当有数据时，每个节拍发送一个，这样就避免了以前发送的时候，需要很长的等待问题。
