Hello
I have hearing aids, which can be connected to devices that support
the Bluetooth ASHA protocol.
https://source.android.com/docs/core/connect/bluetooth/asha
That protocol is open and somewhat well documented. However, it is
only supported on Android devices at the moment. BlueZ on Linux does
not appear to support it.
The idea is with Bluetooth ASHA, one can stream audio from a computer
directly to a pair of hearing aids. Without Bluetooth ASHA, I'm
limited to using a battery powered, clumsy accessory from Cochlear.
I was wondering if it would be worthwhile to support that in BlueZ.
For the record, this has been requested in the past, but hasn't
progressed any further.

Don't think there is any objection to having support for ASHA, the
problem is that most of the companies contributing to BlueZ are
focusing on LE Audio which supersedes ASHA, so the challenge is to
find someone to support this feature.

Glad to hear that I found the right place to ask about this. Do you
think it would be worthwhile to try to find someone to support this
feature, or is the Bluetooth team usually very short staffed?
From a user-perspective, I think that a number of existing hearing
aids support ASHA, and might never receive a firmware update for any
newer Bluetooth Audio Standards. For example, the Cochlear Nucleus 7
supports ASHA, however it has been superseded by the Cochlear Nucleus
8. I really don't know if companies have much incentive to update old
devices that many people rely on.
Considering the price tag on some of those hearing aids, I fear that
this ASHA support request might still be relevant in 10 years.
If it is indeed worthwhile to try and find someone to support this
feature, is there anything I could do to support this?

There are not so many people dedicated to upstream full time, besides
normally for big features like this we normally rely on companies
interested in the feature to support the work upstream.

Well you could consider asking the manufacturer, or google, to support
Linux in general, but I'm afraid they might push back saying they
support just the major OSes.

Just for the archive, as you probably know already from the issue [1]
referenced in your message starting the thread, Arun is working on this
[2], and it is currently reviewed on this list.
Kind regards,
