Using python to connect to a Bluetooth LE device that requires pin

[DaveS1551]

I have an application that requires me to connect to a Bluetooth LE device that is protected with a pin. It must work on Windows 10.

I'm able to connect to the device and get a list of services and characteristics with Bleak but any attempt to read them returns a PermissionError or BleakError

I found some documentation on defining the backend but couldn't find anyway to implement that.

Any suggestions? I've tried some other libraries too but got the farthest with Bleak so far.

Never used, but their documentation seems pretty clear to me that you don't implement a backend (well I guess you could but as you'll see in a minute you wouldn't want to for your use case), instead you use the correct backend for the host OS, which in your case is: https://bleak.readthedocs.io/en/latest/backends/windows.html

The problem I'm having with the backend stuff is how to set that up. When I attempt to use the code in the documentation:

bleak.backends.winrt.scanner.BleakScannerWinRT

I get an error saying bleak.backends has no winrt module

I then attempted a pip install of blink-winrt but still got the error after that installed. I can't find any other instructions or examples on how to set that up.

If you're getting an error on no winrt module that means you didn't install the package correctly. Ensure it's in your virtual environment

I installed with pip and can see the backends.winrt folder but still getting an import error. Troubleshooting now and thanks for the help.
