我正在尝试通过免提配置文件在Android设备与其他手机之间建立蓝牙连接.我正在使用以下代码 -

private static final UUID MY_UUID = UUID.fromString("0000111F-0000-1000-8000-00805F9B34FB"); // UUID for Hands free profile   

// Some code...

            m_oBluetoothSocket = m_oBluetoothDevice.createRfcommSocketToServiceRecord(MY_UUID);     
            m_oBluetoothSocket.connect();

            Log.i(TAG, "Socket Connected");

        }
        catch(Exception e)
        {
            if(null != m_oBluetoothSocket)
            {
                Log.i(TAG, "Closing socket");
                try 
                {
                    m_oBluetoothSocket.close();
                }
                catch (Exception e1) 
                {
