Incopatability with Bluez 5.55

[Poohl]

A recent apt-get dist-upgrade installed bluez version 5.55 on my laptop (running Pop_OS! 20.10, based on Ubuntu 20.10) which seems to not play nicely with this project.

The exact version not working is 5.55-0ubuntu1. If this version is installed the initial bluetooth-setup completes but when the adapter is set to be discoverable and waits for the switch to connect bluetooth just repeatedly turns on and off.

This might be related to #8 but since initialization seems to get past this step, I don't think it is. Moreover the Changelog reads

- Fix issue with handling advertising flags.

so this might be a bluez bug (or the old behaviour was) and the restarting is just a recovery-attempt.

My hotfix is to install these three packages manually (downgrading bluez)

bluez (5.53-0ubuntu3)
bluez-obexd (5.53-0ubuntu3)
bluez-cups (5.53-0ubuntu3) (I have no clue why a printer driver would affect this, but it wouldn't work without)

and then reboot

This appears to be fixed with bluez-5.56 (running arch arm). I was able reproduce the issue on bluez-5.55.
