安卓配对不起作用 - "connection reset by peer"



正如标题所解释的,我很难通过蓝牙将一些数据发送到我的电脑。我正试图将我的android手机作为客户端,将我的电脑作为服务器建立连接。当我试图通过BluetoothSocket.connect()建立连接时,我的手机会提示输入一个引脚。输入后,我的电脑也会提示输入相同的pin,但在我输入之前,connect()-方法会抛出IOException。我假设connect()-方法在我可以在电脑上输入正确的pin之前超时,但我如何让它等待足够长的时间来输入pin?

编辑:将电脑与手机重新配对后,它工作了,因为配对对话框不再出现在我的应用程序中。如果我打开电脑并启动我的应用程序,配对对话框会弹出,但几秒钟后就会消失,插座会抛出异常("对等重置连接")。显然,在配对完成之前,连接会被重置,但为什么呢?

这是我的代码:

private void connectToDevice(BluetoothDevice device)
{
    mBluetoothAdapter.cancelDiscovery();
    BluetoothSocket socket = null;
    try 
    {
        socket = device.createRfcommSocketToServiceRecord(UUID.fromString("00001101-                        0000-  1000-8000-00805F9B34FB"));
    } 
    catch (IOException e) 
    {
        Log.e("HeliRemote", "Couldn't get socket.");
        return;
    }
    try 
    {
        socket.connect();
    } 
    catch (IOException e) 
    {
        try 
        {
            socket.close();
        } 
        catch (IOException e1) 
        {   
            Log.e("HeliRemote", "Couldn't close connection");
        }
        // That's the message I get in LogCat
        Log.e("HeliRemote", "Couldn't connect to Socket.");
        return;
    }
    Log.i("HeliRemote", "connected.");
}

如果有人能就这个问题给我一些好的建议,我会很高兴。

    Method m = mBluetoothDevice.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
        mBluetoothSocket = (BluetoothSocket) m.invoke(mBluetoothDevice, 1);

       // mBluetoothSocket = mBluetoothDevice.createRfcommSocketToServiceRecord(applicationUUID);
        mBluetoothAdapter.cancelDiscovery();
        mBluetoothSocket.connect();


    }
    catch (IOException eConnectException) 
    {
        Log.d(TAG, "CouldNotConnectToSocket", eConnectException);
         closeSocket(mBluetoothSocket);
         return;
    } catch (SecurityException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (NoSuchMethodException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (IllegalArgumentException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (IllegalAccessException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (InvocationTargetException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    }
}

试试这个。。。
