AP模式配网 (AP mode distribution network)

1.设备播完 “请连接的语音” 后会打开一个WIFI热点，热点名称为 camera_+UID 密码为 “12345678”，APP连接时需要获取 WIFI 权限，接着获取 WIFI 列表 (After the device finishes “Please connect voice”, it will open a WIFI hotspot. The hotspot name is camera_+UID and the password is “12345678”. When the APP is connected, you need to obtain WIFI permission, and then get the WIFI list.)。

2.确保手机连上设备的WIFI热点 (Make sure your phone is connected to the device's WIFI hotspot)

3.建立与设备的TCP连接 (Establish a TCP connection to the device)

/**
     * 通过TCP连接设备,发送配置信息到设备，TCP可能连接失败，建议增加重试机制 (TCP is connected to the device and sends configuration information to the device. TCP may fail to connect. It is recommended to add a retry mechanism.)
     */
    private int retryTimes=5;
    private void connectCamera(){
        new Thread(() -> {
            KLog.e("尝试连接 (Try to connect)*************************");
            StringBuilder builder = new StringBuilder();
            TimeZone aDefault = TimeZone.getDefault();
            int rawOffset = aDefault.getRawOffset();
            rawOffset = rawOffset / (1000 * 60);
            String wifiString = new StringBuilder()
                    .append("S=").append(ssid).append(",") //wifi名称 (Wifi name)
                    .append("P=").append(pwd).append(",") //wifi密码 (Wifi password)
                    .append("T=").append(1).append(",") //加密方式 (Encryption)
                    .append("Z=").append(rawOffset).append(",") //设置设备时区，这个字段可以不设置 (Set the device time zone, this field can be set)
                    .append("A=").append("账号").append(",")//用户账号 User account
                    .append("U=").append("公司名称或者app名称")//公司代号 appName
                    .toString();

            try {
                connectByTcp(wifiString);
            } catch (Exception e) {

                e.printStackTrace();
                KLog.e(e.getMessage()+"*"+retryTimes);
                if (retryTimes>0){
                    retryTimes--;
                    connectCamera();
                }
            }
        }).start();
    }

4.接收TCP回调判断是否连接成功 (Receive TCP callback to determine whether the connection is successful)

 private void connectByTcp(String wifiString) throws IOException {
        Socket socket = null;
        socket = new Socket("192.168.201.1",10000);//设备固定的ip和端口 (Device fixed ip and port)
        socket.setSoTimeout(5000);
        Socket finalSocket = socket;
        new Thread(() -> {
            try {
                finalSocket.getOutputStream().write(wifiString.getBytes());
                finalSocket.getOutputStream().flush();
            } catch (IOException e) {
                e.printStackTrace();
            }

        }).start();

        String s = new BufferedReader(new InputStreamReader(socket.getInputStream())).readLine();//成功会返回OK (Successful will return OK)
        KLog.e(s);
        SystemClock.sleep(5000);
    }
