今天花了将近一天的时间来研究ESP8266的SmartConfig功能，这个应该算是wifi云产品的标配。这篇文章先把SmartConfig操作一遍，后面我再写篇文章梳理下物理层的具体协议。

一、准备

ESP8266目前的SDK_v1.2.0支持SmartConfig。将esp_iot_sdk_v1.2.0\examples\smart_config

\目录的例程源码拷贝至app目录即可。

ESP-Touch的APP在乐鑫官网有下载。

微信官方对AirKiss有初步介绍(http://iot.weixin.qq.com/document-7_1.html)，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DEMO(http://iot.weixin.qq.com/download.html)方便开发者的调试。

二、ESP-TOUCH

如下是ESP8266在ESP-TOUCH时的打印信息：

四、总结

ESP8266在V1.2.0版本已经兼容ESP-TOUCH和微信AirKiss，经测试，效果良好。
