블루투스 소켓 질문이요..ㅜㅜ

Question

private void connectClient() {
        try {
            mBluetoothSocket = mConnectedDevice.createRfcommSocketToServiceRecord(mUUID);
        } catch (IOException e) {
            close();
            e.printStackTrace();
            mBluetoothStreamingHandler.onError(e);
            return;
        }
        mWriteExecutor.execute(new Runnable() {
            @Override
            public void run() {
                try {
                    mBluetoothAdapter.cancelDiscovery();
                    mBluetoothSocket.connect();
                    manageConnectedSocket(mBluetoothSocket);
                    callConnectedHandlerEvent();
                    mReadExecutor.execute(mReadRunnable);
                } catch (final IOException e) {
                    Log.e("Test",e.getMessage());
                    close();
                    e.printStackTrace();
                    mMainHandler.post(new Runnable() {
                        @Override
                        public void run() {
                            mBluetoothStreamingHandler.onError(e);
                        }
                    });
                    mIsConnection.set(false);
                    try {
                        mBluetoothSocket.close();
                    } catch (Exception ec) {
                        ec.printStackTrace();
                    }
                }                    
            }
        });
    }

 

블루투스를 이용해서 통신을 하려고 그러는데

mBluetoothSocket.connect(); 이 부분에서 되질 않네요..ㅜㅜ

그래서 로그를 찍어봤더니

 

read failed, socket might closed or timeout, read ret: -1

 

이렇게 뜨는데 어떻게 해야 되나요..?ㅜㅜ
