蓝牙连接到需要PIN的嵌入式设备

Question

我正在编写和Android应用程序，它将检测并连接到已知的嵌入式设备。我的问题是，每当我尝试连接时，它都会引发异常：

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        final String action = intent.getAction();
        if (BluetoothDevice.ACTION_FOUND.equals(action)) {
            try {
            device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
             Toast.makeText(getApplicationContext(),"Try Connecting to device : " + device.getName(),
                      Toast.LENGTH_LONG).show();
               byte[] pin = (byte[]) BluetoothDevice.class.getMethod("convertPinToBytes", String.class).invoke(BluetoothDevice.class, "1234");
                BluetoothDevice.class.getMethod("setPin", byte[].class).invoke(device, pin);
                BlueToothConnect(device);
            }catch(Exception e){}
       }
    }
};

我的BlueToothConnect方法是：

public void BlueToothConnect(BluetoothDevice device){
            if (deviceName.equals(device.getName()))
            {
                 try
                 {

                //mSocket = device.createInsecureRfcommSocketToServiceRecord(MY_UUID);
                    Method m = device.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
                 mSocket = (BluetoothSocket) m.invoke(device, 1);

                     mSocket.connect();
                    GetConnectionDetails();
                     result = device;
                     blueTooth_On_off = 1;
                 }
                catch(Exception  e){
                    text.setText(getStackTrace(e));
                try{

                    result = null;
                    mSocket.close();
                    blueTooth_On_off = 0;
                }
                catch(IOException e1){
                    result = null;
                    blueTooth_On_off = 0;
                    }
                }
            }
}

我遇到异常错误：

java.io.exception：[jsr82] connect：未创建连接（失败或中止）

我在嵌入式设备方面也做不了多少。

以下是我的清单文件：
