我从来没有从BluetoothSocket.connect（）中脱身

Question

任何想法可能是导致问题的原因吗？ 我执行connect()函数，不再执行任何代码。

码：

 void openBT() throws IOException
{
    UUID uuid = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"); //Standard SerialPortService ID
    mmSocket = mmDevice.createRfcommSocketToServiceRecord(uuid);
    mmSocket.connect();
    mmOutputStream = mmSocket.getOutputStream();
    mmInputStream = mmSocket.getInputStream();

    beginListenForData();

    myLabel.setText("Bluetooth Opened");
}

Logcat：

任何想法？

我没有正确的UUID，我通过获取正确的UUID并将其替换为代码来解决它。

如何获取UUID：

ParcelUuid[] list = mmDevice.getUuids();
