device.createInsecureRfcommSocketToServiceRecord 无法正常工作

device.createInsecureRfcommSocketToServiceRecord doesn't work properly

我在这里下载了 BluetoothChat 示例项目: https://android.googlesource.com/platform/development/+/master/samples/BluetoothChat?autodive=0%2F

事实是,当我在两个设备(未配对)上启动应用程序时,它应该连接两个设备而不要求配对两个设备,不是吗? 事实上,当我尝试连接两个设备(未配对)时,它要求配对设备。 我的意思是,BluetoothChatService.java 中有这个函数应该创建一个不安全的套接字。但似乎,这并没有完成他的工作?

   /**
    * This thread runs while attempting to make an outgoing connection
    * with a device. It runs straight through; the connection either
    * succeeds or fails.
    */
   private class ConnectThread extends Thread {
       private final BluetoothSocket mmSocket;
       private final BluetoothDevice mmDevice;
       private String mSocketType;

       public ConnectThread(BluetoothDevice device, boolean secure) {
           mmDevice = device;
        BluetoothSocket tmp = null;
        mSocketType = secure ? "Secure" : "Insecure";

        // Get a BluetoothSocket for a connection with the
        // given BluetoothDevice
        try {
            if (secure) {
                tmp = device.createRfcommSocketToServiceRecord(
                        MY_UUID_SECURE);
            } else {
                tmp = device.createInsecureRfcommSocketToServiceRecord(
                        MY_UUID_INSECURE);
            }
        } catch (IOException e) {
            Log.e(TAG, "Socket Type: " + mSocketType + "create() failed", e);
        }
        mmSocket = tmp;
    }

有人可以解释一下为什么它要求配对这两个设备吗? createInsecureRfcommSocketToServiceRecord 方法不应该要求配对未配对的设备,对吗? X) 我真的很困惑。

createInsecureRfcommSocketToServiceRecord() 有的 "insecure" 设备用于通信的密钥,低于蓝牙 2.1,未加密。那就是"unsecure".

但这并没有改变这样一个事实,即如果 MAC 地址不在配对数据库中,那么总会有提示。

所以是的,它会提示。
