No devices discovered on Windows

[0ge]

• bleak version: 0.9.0, 0.9.1, 0.10.0
• Python version: 3.9
• Operating System: Win10

Description

I'm running the scanning example on a Windows machine.
However, it does not discover any devices.

What I Did

Installed bleak with pip install bleak.
Running the example from both VSCode and command prompt. (Different command to enable logging)

I've tried with $env:BLEAK_LOGGING=1 and also logging.basicConfig(level=logging.DEBUG) but I don't see any logging.
The only output is DEBUG:asyncio:Using proactor: IocpProactor

It runs on another machine, so I'm thinking there is something related to the installation?
Unfortunately, I did not do the installation on the other machine.

Any help would be greatly appreciated.

Maybe Bluetooth is turned off on that machine?

[0ge]

No, its turned on.
(Thanks for letting me know of the discussions feature of GitHub!)

If I go to Windows Settings I can scan and discover some Bluetooth devices.

* Python version: 3.9

Try Python 3.8.

From what I read, 3.9 support is there in pythonnet but there were some reported crashes, so they didn't publish a binary wheel.

@dlech Ah, I had not seen that. Good to know.

@0ge Could you install a different branch on either 3.9 or 3.7 and run your program again:

pip install --force-reinstall https://github.com/hbldh/bleak/archive/feature/winrt2.zip#egg=bleak

This is a different way of interacting with the Windows UWP BLE. See if that makes any changes. If not, I would suspect that the problem is in Windows and not in Bleak...

[0ge]

Still nothing. (Both 3.7 and 3.9)

No ideas on what is "wrong" in Windows?

[hbldh]

Get the Bluetooth LE Explorer from the Windows Store and try that (code here: https://github.com/Microsoft/BluetoothLEExplorer). That uses the same APIs that Bleak does. If that works and Bleak doesn't, then something is most probably wrong in Bleak.
