资源介绍:

1、创作起因：网上找了很久，都没有关于ESP8266 WIFI通过softap方式配网开源例程，基本都是smartconfig airkiss方式一键配网，这种方式受手机、路由器等兼容性影响，配网成功率低，用户体验差。问 ESP8266乐鑫厂家，得到回复是esp-01s这个模块内存太小，建议更换带蓝牙的模块，这样这边设计工作量比较大，什么都需要更改。但我不死心，不放弃自己根据softAP配网协议，编写的此代码，调试测试终于成功，配网成功率100%。 2、源码采用性价比最高的esp-01s WIFI模块，当然配置高的模块同样兼容； 3、本源码全部开源，部分用到官网库函数，现决定将此源码分享给大家，希望能帮助到需要的朋友。 4、目前这个源码已经批量在产品中运用由于配网失败导致退货的问题一直是Wifi设备的一个痛点，所以各大厂家一直在研究Wifi配网技术。目前配网技术有以下几种一键配网（Smartconfig）设备热点配网（Soft AP）强烈推荐蓝牙配网（Bleconfig）零配（Zeroconfig）手机热点配网（Phone as AP）
