Bluetooth configuration Bluetooth configuration
======================= =======================
Using the same format as the :ref:`ALSA monitor <config_alsa>`, the Bluetooth audio and MIDI devices are managed by the BlueZ and BlueZ-MIDI
configuration file ``wireplumber.conf.d/bluetooth.conf`` configures monitors, respectively.
the Bluetooth devices and nodes created by WirePlumber.
* *Settings* Both monitors are enabled by default and can be disabled using the
``monitor.bluez`` and ``monitor.bluez-midi`` :ref:`features <config_features>`
in the configuration file.
Example: As with all device monitors, both of these monitors are implemented as SPA
plugins and are part of PipeWire. WirePlumber merely loads the plugins and lets
them do their work. These plugins then monitor the BlueZ system-wide D-Bus
service and create device and node objects for all the connected Bluetooth audio
and MIDI devices.
.. code-block:: Logind integration
------------------
monitor.bluez.properties = { The BlueZ monitors are integrated with logind to ensure that only one user at a
bluez5.roles = "[ a2dp_sink a2dp_source bap_sink bap_source hsp_hs hsp_ag hfp_hf hfp_ag ]" time can use the Bluetooth audio devices. This is because on most Linux desktop
} systems, the graphical login manager (GDM, SDDM, etc.) is running as a separate
user and runs its own instance of PipeWire and Wireplumber. This means that if a
user logs in graphically, the Bluetooth audio devices will be automatically
grabbed by the PipeWire/WirePlumber instance of the graphical login manager,
and the user that logs in will not get access to them.
Enabled headset roles (default: [ a2dp_sink a2dp_source bap_sink bap_source hsp_hs hsp_ag hfp_hf hfp_ag ]). To overcome this, the BlueZ monitors are integrated with logind and are only
Some headsets (e.g. Sony WH-1000XM3) do not work with both hsp_ag and hfp_ag enabled, allowed to create device and node objects for Bluetooth audio devices if the
so `hsp_ag` and `hfp_ag` are disabled by default. user is currently on the "active" logind session.
Supported roles: In some cases, however, this behavior is not desired. For example, if you
manually switch to a TTY and log in there, you may want to keep the Bluetooth
audio devices connected to the now inactive graphical session. Or you may want
to have a dedicated user that is always allowed to use the Bluetooth audio
devices, regardless of the active logind session, for example for a (possibly
headless) music player daemon.
- ``hsp_hs`` (HSP Headset) To disable this behavior, you can set the ``monitor.bluez.seat-monitoring``

MIDI Monitor Properties
-----------------------
The BlueZ MIDI monitor SPA plugin (``api.bluez5.midi.enum``) may, in the future,
support properties that can be used to configure it when it is loaded. These
properties can be set in the ``monitor.bluez-midi.properties`` section of the
WirePlumber configuration file. At the moment of writing, there are no
properties that can be set there.
In addition, the BlueZ MIDI monitor supports a list of MIDI server node names
that can be used to create Bluetooth LE MIDI service instances. These
server node names can be set in the ``monitor.bluez-midi.servers`` section of
the WirePlumber configuration file.
Example:
.. code-block::
monitor.bluez-midi.servers = [ "bluez_midi.server" ]
.. note::
Typical BLE MIDI instruments have one service instance, so adding more than
one here may confuse some clients.
Rules
-----
When device and node objects are created by the BlueZ monitor, they can be
configured using rules. These rules allow matching the existing properties of
these objects and updating them with new values. This is the main way of
configuring Bluetooth device settings.
These rules can be set in the ``monitor.bluez.rules`` section of the WirePlumber
configuration file.
Example:
.. code-block::
monitor.bluez.rules = [
{
matches = [
{
## This matches all bluetooth devices.
device.name = "~bluez_card.*"
}
]
actions = {
update-props = {
bluez5.auto-connect = [ hfp_hf hsp_hs a2dp_sink hfp_ag hsp_ag a2dp_source ]
bluez5.hw-volume = [ hfp_hf hsp_hs a2dp_sink hfp_ag hsp_ag a2dp_source ]
bluez5.a2dp.ldac.quality = "auto"
bluez5.a2dp.aac.bitratemode = 0
bluez5.a2dp.opus.pro.application = "audio"
bluez5.a2dp.opus.pro.bidi.application = "audio"
} }
} }
] }
{
matches = [
{
## Matches all sources.
node.name = "~bluez_input.*"
}
{
## Matches all sinks.
node.name = "~bluez_output.*"
}
]
actions = {
update-props = {
bluez5.media-source-role = "input"
Allows changing well-known node settings. # Common node & audio adapter properties may also be set here
node.nick = "My Node"
priority.driver = 100
priority.session = 100
node.pause-on-idle = false
resample.quality = 4
channelmix.normalize = false
channelmix.mix-lfe = false
session.suspend-timeout-seconds = 5
monitor.channel-volumes = false
}
}
}
]
In addition, allows changing some MIDI-specific settings: Device properties
^^^^^^^^^^^^^^^^^
.. code-block:: The following properties can be set on device objects:
node.latency-offset-msec = 0 .. describe:: bluez5.auto-connect

Supported values are: ``hfp_hf``, ``hsp_hs``, ``a2dp_sink``, ``hfp_ag``,
``hsp_ag`` and ``a2dp_source``.
:Default value: ``[]``
:Type: array of strings
.. describe:: bluez5.hw-volume
Enable hardware volume controls on these profiles.
Supported values are: ``hfp_hf``, ``hsp_hs``, ``a2dp_sink``, ``hfp_ag``,
``hsp_ag`` and ``a2dp_source``.
:Default value: ``[ hfp_ag hsp_ag a2dp_source ]``
:Type: array of strings
.. describe:: bluez5.a2dp.ldac.quality
LDAC encoding quality.
Available values: ``auto`` (Adaptive Bitrate, default), ``hq`` (High
Quality, 990/909kbps), ``sq`` (Standard Quality, 660/606kbps) and ``mq``
(Mobile use Quality, 330/303kbps).
:Default value: ``auto``
:Type: string
.. describe:: bluez5.a2dp.aac.bitratemode
AAC variable bitrate mode.
Available values: 0 (cbr, default), 1-5 (quality level).
:Default value: ``0``
:Type: integer
.. describe:: bluez5.a2dp.opus.pro.application
Opus Pro Audio encoding mode.
Available values: ``audio``, ``voip``, ``lowdelay``.
:Default value: ``audio``
:Type: string
.. describe:: bluez5.a2dp.opus.pro.bidi.application
Opus Pro Audio encoding mode for bidirectional audio.
Available values: ``audio``, ``voip``, ``lowdelay``.
:Default value: ``audio``
:Type: string
.. describe:: device.profile
The profile that is activated initially when the device is connected.
Available values: ``a2dp-sink`` (default) or ``headset-head-unit``.
:Default value: ``a2dp-sink``
:Type: string
Node properties
^^^^^^^^^^^^^^^
The following properties can be set on node objects:
.. describe:: bluez5.media-source-role
Media source role, ``input`` or ``playback``. This controls how a media
source device, such as a smartphone, is used by the system. Defaults to
``playback``, playing the incoming stream out to speakers. Set to ``input``
to use the smartphone as an input for apps (like a microphone).
:Default value: ``playback``
:Type: string
MIDI Rules
----------
Similarly to the above rules, the BlueZ MIDI monitor also supports rules that
can be used to configure MIDI nodes when they are created.
These rules can be set in the ``monitor.bluez-midi.rules`` section of the
WirePlumber configuration file.
Example:
.. code-block::
monitor.bluez-midi.rules = [
{
matches = [
{
node.name = "~bluez_midi.*"
}
]
actions = {
update-props = {
node.nick = "My Node"
priority.driver = 100
priority.session = 100
node.pause-on-idle = false
session.suspend-timeout-seconds = 5
node.latency-offset-msec = 0
}
}
}
]
.. note::
It is possible to also match MIDI server nodes by testing the ``node.name``
property against the server node names that were set in the
``monitor.bluez-midi.servers`` section of the WirePlumber configuration file.
MIDI-specific properties
^^^^^^^^^^^^^^^^^^^^^^^^
.. describe:: node.latency-offset-msec
Latency adjustment to apply on the node. Larger values add a
constant latency, but reduces timing jitter caused by Bluetooth
transport.
:Default value: ``0``
:Type: integer (milliseconds)
