Hi folks,
I've written an implementation of the Android specification for
streaming to hearing aids over Bluetooth LE, ASHA[1]. This predates the
LE audio specification, and has been supported in hearing aids for a
while now, so I think this is worth supporting as these devices should
continue to be in use for several years.
I've reused the MediaEndpoint1 and MediaTransport1 interfaces at Luiz'
suggestion. The flow is slightly different from A2DP and LE Audio in
that there isn't really a negotiation step, so the endpoint and
transport are both available on connection.
Also included is a script to stream arbitrary audio to an ASHA device,
which is handy for making sure that the implementation does work. I have
tested this against a reference implementation on an onsemi RSL10 board.
The current implementation is written with a single device in mind. My
plan is to take this to completion along with a PipeWire implementation
to expose a single device for playback, and then do a second pass to
support a pair of devices.
Cheers,
Arun

This implements the server role for the Audio Streaming for Hearing Aid
specification[1].
The implementation registers a remote endpoint using a subset of the
MediaEndpoint1 interface, without any mechanism for setting/selecting a
configuration, as this is all static in the spec for now. Also exposed
on connection is a MediaTransport1 object, which can be used to obtain
an fd to stream to the device.

I'd suggest we split the protocol portion from the plugin and put it
under src/shared so we can do unit testing without the D-Bus blocks,
Id got with bt_asha for instance name, we can do it later if you don't
feel like it is necessary right now.

Hey Luiz,
Thank you for the quick review!

Good point. I guess both the L2CAP header and the SDU length are
accounted for. I've fixed this to be 161 now (sequence number + data).

Done.

I'm exposing the bitmask from DeviceCapabilities, which is
theoretically a set of codecs. In practice, since we only have one
codec, it will always be 0x2, but I thought I'd stick to the semantics
of the spec.

Ah, I did not follow the reason for that split previously. Done now.

Thank you for the quick review! I'll send out a v2 with these fixes
and whatever the linter caught.

We convert from the spec definition of the range to the DBus API range
to make it easier for clients to not have to worry about that detail,
and share an implementation with other uses of MediaTransport1.

Plays out an audio file to the device. Depends on GStreamer for media
file reading and decoding (specifically, gstreamer core,
gst-plugins-base, gst-ffmpeg, and gst-python, or equivalent packages).

While I don't mind having a python example I think we are much better
of adding such support in bluetoothctl, most should already work with
transport submenu but perhaps we want to add support for gstreamer
pipeline instead of just a file which would be useful for creating
A2DP sbc and BAP lc3 streams.

Makes sense, I can take a look at this, but if possible I'd like to
punt this till I get the end-to-end flow working with the PipeWire
BlueZ modules.

These directories are created when running scripts in test/ in-tree, and

This implements the server role for the Audio Streaming for Hearing Aid
specification[1].
The implementation registers a remote endpoint using a subset of the
MediaEndpoint1 interface, without any mechanism for setting/selecting a
configuration, as this is all static in the spec for now. Also exposed
on connection is a MediaTransport1 object, which can be used to obtain
an fd to stream to the device.

* [PATCH BlueZ,v3 1/5] src/shared: Add initial implementation for an ASHA profile
@ 2024-05-15 20:15 Arun Raghavan
2024-05-15 23:48 ` ASHA plugin bluez.test.bot
0 siblings, 1 reply; 19+ messages in thread
From: Arun Raghavan @ 2024-05-15 20:15 UTC (permalink / raw)
To: linux-bluetooth; +Cc: Arun Raghavan
This implements the server role for the Audio Streaming for Hearing Aid
specification[1]. Includes basic ability to probe the ASHA GATT service,
as well as starting/stopping streaming.

This implements the server role for the Audio Streaming for Hearing Aid
specification[1]. Includes basic ability to probe the ASHA GATT service,
as well as starting/stopping streaming.

* [PATCH BlueZ,v10 1/3] src/shared: Add initial implementation for an ASHA profile
@ 2024-06-12 16:20 Arun Raghavan
2024-06-12 18:59 ` ASHA plugin bluez.test.bot

From: Arun Raghavan @ 2024-06-12 16:20 UTC (permalink / raw)
To: linux-bluetooth; +Cc: Arun Raghavan
This implements the server role for the Audio Streaming for Hearing Aid
specification[1]. Includes basic ability to probe the ASHA GATT service,
as well as starting/stopping streaming.
