  • bleak version: 0.21.1
  • Python version: latest
  • Operating System: Windows
  • BlueZ version (bluetoothctl -v) in case of Linux:

Description

In workaround function:

async def acquire_mtu(client: BleakClient):
    from bleak.backends.bluezdbus.client import BleakClientBlueZDBus
    if type(client._backend) is not BleakClientBlueZDBus:
        return

    # in Linux acquire mtu should be called in order to have more than 23
    await client._backend._acquire_mtu()

When import BleakClientBlueZDBus called in Windows, following exception raised:
No module named 'dbus_fast'

Code: https://github.com/vovagorodok/ArduinoBleOTA/blob/98934bd7e069ddaf090b5ae60cf466e3f4a072c0/tools/uploader.py#L87

Should it be fixed in bleak side or script should be changed somehow?

The problem isn't with Bleak but rather with the code you linked. It could be fixed by wrapping the import statement in a try block or by putting this line in an if block so that it only runs on Linux.
