ORG.BLUEZ.MEDIAENDPOINT(5) Linux System Administration ORG.BLUEZ.MEDIAENDPOINT(5)

NAME

org.bluez.MediaEndpoint - BlueZ D-Bus MediaEndpoint API documentation

INTERFACE

unique name (Server role) org.bluez (Client role)
org.bluez.MediaEndpoint1
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.
Configured transport object.
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:

See Capabilities property.
See Metadata property.
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:


See MediaEndpoint Properties for their possible values.

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


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.
Indicates endpoint support framing.

Possible Values:

0x00
Unframed PDUs supported.
0x01
Unframed PDUs not supported.

Indicates endpoint preferred PHY.

Possible values:

LE 1M preferred.
LE 2M preferred.
LE Coded preferred.

Indicates endpoint preferred number of retransmissions.
Indicates endpoint maximum latency.
Indicates endpoint minimum presentation delay.
Indicates endpoint maximum presentation delay.
Indicates endpoint preferred minimum presentation delay.
Indicates endpoint preferred maximum presentation delay.
