Comment 43 for bug 1903048

There's a version of bluez with the patches that I've submitted upstream built in the following PPA against the hirsute branch (the patch changes are pretty minimal; basically amounts to removal of the arbitrary sleep(1) as during December's tests I couldn't find a single platform that actually required that, even amongst the Pi's we don't support like the zero):

I'm happy to convert that to a git-ubuntu branch if that's preferable. Once sponsored, we should consider SRU'ing to focal given that Pi400 support is now being SRU'd there generally.
