Description

I run uart_service.py and I encountered asyncio.exceptions.InvalidStateError: invalid state.

What I Did

1. Downloading bleak v0.21.1 source code.
2. Unzipping bleak-0.21.1.zip to D:\workspace_Python folder.
3. cd D:\workspace_Python\bleak-0.21.1\examples
4. python3 uart_service.py

Logs

The example is working for me. So more logs will be required to understand the problem.
