ESP8266学习笔记4：ESP8266的SmartConfig(转)

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，我还写了另一篇文章梳理了物理层的具体协议，点击这里可以看到。

一、准备
http://img.blog.csdn.net/20150714204340262?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
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

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。
