搞定了SmartConfig,前头也用cURL玩过了yeelink,今天就编写代码,让ESP8266接入yeelink

转载请注明:http://blog.csdn.net/sadshen/article/details/46897479

一、代码处理。

主要是将httpsample加入到SmartConfig_DEMO中。ESP8266的运行流程是SmartConfig->DNS->Connect yeelink->Get /devices

这里的pheadbuffer 格式要注意加上U-ApiKey。我是通过wireshark捕捉了curl Get /devices的动作才知道要怎么写的。
