Bleak-winrt version~=1.1.1

Unable to write into a characteristic, but reading and notifications work fine

I checked through BLE Scanner on Android and BleuIO, writing works fine both ways, so there is an issue with Bleak or WinRT. Device is not receiving anything (I monitor through COM port)

I tried older versions of Bleak-winrt, getting the same error.

Here is a piece of code:

a = await self.client.get_services()
                                  for c in a.characteristics.values():
                                    try:
                                        b = await self.client.write_gatt_char(c, B"123ABC")  # Issue is in here
                                        print(b)
                                    except Exception as e:
                                        print("Test error 2:", e)
                                        if "Access Denied" not in str(e):
                                            print("Have a look!", e)
                                    await asyncio.sleep(0.1)

For some reason, the -include and -exclude options don't work for cppwinrt.exe like they do for pywinrt.exe, so it ends up generating a bunch of files that we don't need.

I can generate bleak_winrt-1.2.0-cp311-cp311-win_amd64.whl file by running "python3 setup.py bdist_wheel" command. How to replace bleak Windows backend with bleak_winrt-1.2.0-cp311-cp311-win_amd64.whl file?

The BluetoothLEAdvertisementReceivedEventArgs.BluetoothAddressType does not seem to be accessible from the Python BluetoothLEAdvertisementReceivedEventArgs type.
