Because of the circumstances, I can't use pybluez on Windows 10.
So I'm going to use Python's socket. But you can't designate uuid in Python Socket.
D/BluetoothUtils: isSocketAllowedBySecurityPolicy start : device null
2021-10-09 03:43:56.736 14690-17661/com.example.bluetooth I/BluetoothSocket: connect() for device 98AF65 called by pid: 14690
2021-10-09 03:43:56.738 14690-17661/com.example.bluetooth W/BluetoothAdapter: getBluetoothService() called with no BluetoothManagerCallback
This error occurs on Android.
Please teach me the way.
