I’m running Home Assistant Core, and I’m trying to update my Python to 3.8.0, as the new Home Assistant releases require it… I tried to update from source with this tutorial: https://installvirtual.com/how-to-install-python-3-8-on-raspberry-pi-raspbian/ and it worked, however the bluetooth support is not working for my Xiaomi Thermometer… Does someone knows how should be the correct way to update and support bluetooth?
You should really have gone for 3.8.7, not 3.8.0. That said, the guide is missing a number of libraries, including Bluetooth, which would explain your problem.
