I am mainly here for the Bluetooth.
Most repeated is about deprecated BlueZ tools:
hciattach, hciconfig, hcitool, hcidump, rfcomm, sdptool, ciptool, and gatttool were deprecated by the BlueZ project in 2017. If you are following a tutorial that uses them, there is a chance that it might be out of date

To get Bluetooth debug information on Linux:
- Are you able to connect to the device using
service bluetooth statusshow errors?
When running your script have separate terminals open with the following running to get more debug information:
journalctl -f -u bluetooth
sudo busctl monitor org.bluez
