Example LC3 BAP Broadcast source

>endpoint.register 00001852-0000-1000-8000-00805f9b34fb 0x06
>Auto Accept (yes/no): y
>Max Transports (auto/value): a

>Auto Accept (yes/no): y
>Max Transports (auto/value): a
>Locations: 3
>Supported Context (value): 1

Note:

If running the setup with an audio server that has LE Audio support (such as PipeWire) it will automatically register endpoints according to the configured roles. For more details about configuring a Broadcast Source with PipeWire check: https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/doc/dox/config/pipewire-props.7.md

unregister

Unregister Endpoint.

Usage

> unregister <UUID/object>

Uses

org.bluez.Media(5) method UnregisterEndpoint

<UUID/object>

Either the service UUID or the object path of the endpoint to unregister

Example Unregister LC3 source endpoint by UUID

> unregister 00002bcb-0000-1000-8000-00805f9b34fb

Example Unregister LC3 sink endpoint by UUID

> unregister 00002bc9-0000-1000-8000-00805f9b34fb

Example Unregister broadcast source endpoint by UUID

> unregister 00001852-0000-1000-8000-00805f9b34fb

Example Unregister broadcast sink endpoint by UUID

> unregister 00001851-0000-1000-8000-00805f9b34fb

Example Unregister endpoint by object path

> unregister /local/endpoint/ep0

Example Unregister another endpoint by object path

> unregister /local/endpoint/ep1

Example Unregister source endpoint by path

> unregister /local/endpoint/source0

Example Unregister sink endpoint by path

> unregister /local/endpoint/sink0

Note:

If the endpoint was registered by an audio server, it can't be unregistered from bluetoothctl. This must be done by the audio server as well.

config

Configure Endpoint.

Usage

> config <endpoint> <local endpoint> [preset]

Uses

org.bluez.MediaEndpoint(5) method SetConfiguration

<endpoint>

Path to the remote endpoint to configure

<local endpoint>

Path to the local endpoint to use for the configuration

[preset]

Audio quality preset name (optional, auto-detected if omitted)

Example Configure remote endpoint with local endpoint (auto preset)

> config /org/bluez/hci0/dev_00_11_22_33_44_55/ep0 /local/endpoint/ep0

Example Configure LE Audio Unicast with BAP setting 32_1_1

> config /org/bluez/hci0/dev_00_11_22_33_44_55/ep0 /local/endpoint/ep0 32_1_1

Example Configure LE Audio Broadcast Source
