  ******************************************************************************
    APUConfig配网绑定流程
    设备端
    1.获取设备MAC XX:XX:XX:XX:XX:XX
    2.控制WIFI发出固定无线网  名称:wifi_8266_bind    密码:11223344  
    3.UDP 监听固定端口5556
    4.等待接收客户端的消息. 消息格式{"ssid":"qqqqq","pwd":"11223344"} 
    5.提取路由器名称和密码,连接路由器
    6.获取链接路由器后分的的IP. 假设是192.168.10.2 以防后期实现局域网通信备用 
    7.UDP发送数据,{"mac":"XX:XX:XX:XX:XX:XX","ip":"192.168.10.2"}
    
    APP/小程序/上位机
    1.提示用户连接自己的路由器,长按设备按钮使得设备进入UDP监听状态,提示用户输入路由器密码
    2.用户点击绑定设备 , 控制手机尝试连接 名称为 wifi_8266_bind 的无线 (内部控制)
    3.成功连接无线,往192.168.4.1:5556 UDP发送路由器信息,1S 1次
    4.接收到 {"mac":"XX:XX:XX:XX:XX:XX","ip":"192.168.10.2"}
    5.绑定成功
    8.完
