Hi thanks for indulging me. Wondering if this hearing aid streaming
service can be implemented in the Linux bluetooth stack. So far only
found in iPhone and some Android phones
There is more information at https://source.android.com/devices/bluetooth/asha
I would be happy to help with testing if anyone is interested.
I have a Nucleus7 CochlearSpeech Processor and I can connect to it
with this RPi4B running 5.4.71-v7l+ with bluetoothd v5.5
bluetoothctl v5.49 gives the following output:

It should be possible to implement it, but it probably doesn't make
sense to implement it as a plugin to bluetoothd given its proprietary
status it might be better to implement as part of an application.
