BlueZ D-Bus MediaEndpoint API documentation

Interface

Service

unique name (Server role) org.bluez (Client role)

Interface

org.bluez.MediaEndpoint1

Object path

freely definable (Server role) [variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX/sepX (Client role)

Methods

void SetConfiguration(object transport, dict properties)

Set configuration for the transport.

object transport

Configured transport object.

dict properties

Configured org.bluez.MediaTransport(5) properties.

For client role transport must be set with a server endpoint object which will be configured and the properties must contain the following properties:

array{byte} Capabilities [Mandatory]

See Capabilities property.

array{byte} Metadata [ISO only]

See Metadata property.

dict QoS [ISO only]

See org.bluez.MediaTransport(5) QoS property.

array{byte} SelectConfiguration(array{byte} capabilities)

Select preferable configuration from the supported capabilities.

Returns a configuration which can be used to setup a transport, see org.bluez.MediaTransport(5) for possible values.

Note: There is no need to cache the selected configuration since on success the configuration is send back as parameter of SetConfiguration.

dict SelectProperties(dict capabilities)

Select BAP unicast configuration from the supported capabilities:

object Endpoint
array{byte} Capabilities
array{byte} Metadata
uint32 Locations
uint32_t ChannelAllocation
dict QoS

byte Framing

byte PHY

uint16 MaximumLatency

uint32 MinimumDelay

uint32 MaximumDelay

uint32 PreferredMinimumDelay

uint32 PreferredMaximumDelay

See MediaEndpoint Properties for their possible values.

Returns a configuration which can be used to setup a transport:

array{byte} Capabilities

array{byte} Metadata [optional]

dict QoS

See SetConfiguration for their possible values.

Note: There is no need to cache the selected properties since on success the configuration is send back as parameter of SetConfiguration.

void ClearConfiguration(object transport)

Clear transport configuration.

void Release()

This method gets called when the service daemon unregisters the endpoint. An endpoint can use it to do cleanup tasks. There is no need to unregister the endpoint, because when this method gets called it has already been unregistered.

MediaEndpoint Properties

string UUID [readonly, optional]

UUID of the profile which the endpoint is for.

byte Codec [readonly, optional]

Assigned number of codec that the endpoint implements. The values should match the profile specification which is indicated by the UUID.

uint32_t Vendor [readonly, Optional]

Vendor-specific Company ID, Codec ID tuple that the endpoint implements.

It shall be set to appropriate value when Vendor Specific Codec (0xff) is used.

array{byte} Capabilities [readonly, optional]

Capabilities blob, it is used as it is so the size and byte order must match.

array{byte} Metadata [readonly, Optional]

Metadata blob, it is used as it is so the size and byte order must match.

object Device [readonly, optional]

Device object which the endpoint is belongs to.

bool DelayReporting [readonly, optional]

Indicates if endpoint supports Delay Reporting.

uint32 Locations [readonly, optional, ISO only, experimental]

Indicates endpoint supported locations.

uint16 SupportedContext [readonly, optional, ISO only, experimental]

Indicates endpoint supported audio context.

uint16 Context [readonly, optional, ISO only, experimental]

Indicates endpoint available audio context.

dict QoS [readonly, optional, ISO only, experimental]

Indicates QoS capabilities.

byte Framing

Indicates endpoint support framing.

Possible Values:

0x00

Unframed PDUs supported.

0x01

Unframed PDUs not supported.

byte PHY

Indicates endpoint preferred PHY.

Possible values:

bit 0

LE 1M preferred.

bit 1

LE 2M preferred.

bit 2

LE Coded preferred.

byte Retransmissions

Indicates endpoint preferred number of retransmissions.

uint16 MaximumLatency

Indicates endpoint maximum latency.

uint32 MinimumDelay

Indicates endpoint minimum presentation delay.

uint32 MaximumDelay

Indicates endpoint maximum presentation delay.

uint32 PreferredMinimumDelay

Indicates endpoint preferred minimum presentation delay.

uint32 PreferredMaximumDelay

Indicates endpoint preferred maximum presentation delay.
