Bluetooth Handsfree Bounty

[33YN2]

For over two years, there have been many scattered posts from people wanting
to be able to use their phones to make and receive calls using hands-free
bluetooth devices.  This has been standard with android phones for well over
10 years.

From what I can see with pipewire and wireplumber, and from what others have
said, it is just a matter of creating the proper audio profile
(pipewire/wireplumber configuration) to route the audio between bluetooth and
the modem.  If there was proper documentation of the relevant systems I would
figure it out myself and post the solution here.

There are certainly people who understand pipewire/wireplumber well enough
that it would be fairly straightforward for them to solve this problem if
they thought it worth the effort.

I will give $50 to the first person or project (Mobian for example) who,
before June 1, 2024, will come up with a solution compatible with hfp 1.5 and
later, and make it publicly available in a way that the common pinephone
(original) user can make use of it.  This could be somthing like an
installable package or upgrade to a package, a script to make changes or, if
it came with complete step-by-step instructions, as a set of edits to
configuration files.

I realize $50 by itself might not be enough motivation so I would ask those
who also need this to at least register their desire for it by taking the
time to add a post to this thread, and for those who can, by also offering
additional money.

Maybe someone with the knowledge just needs to know that people need

I recall a website that allowed people to put in money and when a developer completed their request they would check off on it and the developer gets the money. Forgot what its called but it would be good in this case.

I'd be willing to put $200 toward this bounty.
