[dlech]

pythonnet doesn't ship a binary wheel for Python 3.9. You can use Python 3.8 or refer to pythonnet docs to see how to build it from source for Python 3.9 or try out the winrt2 branch which provides an alternative to pythonnet.

[hbldh]

You might install version 0.12.0b1 from the develop branch to get a preview of the Python 3.9 support in Windows:

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