examples/service_explorer.py Unhandled timeout error in service_explorer.py / CentralManagerDelegate.py on macOS

[jsmif]

• bleak version: bleak-0.21.0a
• Python version: Python 3.11.3
• Operating System: macOS 13.3.1 (a)

Description

Testing examples/service_explorer.py on macOS since it doesn't work for me on Linux (#1333 )

What I Did

python3 service_explorer.py --address F8607851-010B-B680-D5E6-55C07864A794
2023-06-14 09:06:40,788 __main__ INFO: starting scan...

    await future
asyncio.exceptions.CancelledError

The above exception was the direct cause of the following exception:

    raise TimeoutError from exc_val
TimeoutError

This occurred when attempting to connect to an Apple AirTag that was listed by BleakScanner.discover(). Note, service_explorer.py has worked for me for at least one device though.

Logs

Unfortunately I cannot provide logs as that would provide my exact physical location (see: wigle.net)

[dlech]

Did the OS prompt for any kind of authentication?

It is not possible to diagnose further without additional logs.
