ESP8266学习笔记5：ESP8266接入yeelink_esp8266接入yeelink平台-优快云博客

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。

一、代码处理。

主要是将http的sample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。
