26-ESP8266 SDK开发基础入门篇--编写WIFI模块 SmartConfig/Airkiss 一键配网

https://www.cnblogs.com/yangfengwu/p/11427504.html

SmartConfig/Airkiss 配网需要APP/微信公众号,这节大家先使用我做好的APP/微信公众号

其余的步骤等写完8266的配网程序,在下面演示.

如果想自己实现微信绑定可以看↓ (注:配置过程和源码全部是公开的,大家看文章即可实现)

如果你已经有做网页的经验了,可以直接

如果你没有做过网页,你需要先看

然后需要把微信小程序篇的所有章节从头到尾看一遍

现在开始写WIFI的配网程序

其实官方给了例子

咱把例子写个单独的.C和.H文件,方便咱后期使用

然后主函数

    wifi_station_disconnect();

    wifi_set_event_handler_cb(wifi_event_monitor_handle_event_cb);

    wifi_set_opmode(STATION_MODE);
    smartconfig_set_type(SC_TYPE_ESPTOUCH_AIRKISS);//SmartConfig  +  AirKiss
    xTaskCreate(smartconfig_task, "smartconfig_task", 256, NULL, 2, NULL);

现在是模块一启动就进去配网...

编译出错

加上    -lairkiss\

下载进去,咱先测试下

SmartConfig:

下载完WIFI的程序,复位下WIFI

这个APP是我做的一个面向开发使用的,该APP源码获取方式:  https://www.cnblogs.com/yangfengwu/p/11249674.html

AirKiss :  关注我的这个测试用的公众号

复位WIFI模块

好,现在优化下

按下固件按钮(GPIO0)大约3S, 让GPIO2那个灯快闪,进入配网模式,然后60S超时检测.还有就是不让WIFI打印官方内部写的东西(打印的东西太多了...)
