Question

正如标题所解释的那样，我很难通过蓝牙将一些数据发送到我的电脑上。我正在尝试建立与我的Android手机连接作为客户端和我的PC作为服务器。当我尝试通过BluetoothSocket.connect（）实际建立连接时，我的手机会提示输入引脚。输入后我的PC也会提示相同的引脚，但在我输入之前，connect（） - 方法会抛出IOException。我假设在我可以在我的电脑上输入正确的引脚之前，connect（） - Method超时，但我怎么能让它等待足够长的时间让我输入PIN？

编辑：将PC与我的手机重新配对后，它工作正常，因为配对对话框不再出现在我的应用程序中。如果我取消配对PC并启动我的应用程序，配对对话框会弹出但几秒钟后会消失，并且套接字会抛出异常（“通过对等方重置连接”）。显然在配对完成之前重置了连接，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任何好的建议，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);
    }
}
