org.bluez.MediaTransport

fd, uint16, uint16 Acquire()

Acquire transport file descriptor and the MTU for read and write respectively.

Possible Errors:

fd, uint16, uint16 TryAcquire()

Acquire transport file descriptor only if the transport is in "pending" state at the time the message is received by BlueZ. Otherwise no request will be sent to the remote device and the function will just fail with org.bluez.Error.NotAvailable.

Possible Errors:

void Release()

Releases file descriptor.

void Select()

Applicable only for transports created by a broadcast sink. This moves the transport from "idle" to "broadcasting".

This allows callers to select which BISes he wishes to sync to via a 2 step process:

Possible Errors:

void Unselect()

Applicable only for transports created by a broadcast sink. This moves the transport from "broadcasting" or "active" to "idle".

This allows callers to terminate the sync to a BIS to via a 2 step process:

Possible Errors:

object Device [readonly]

Device object which the transport is connected to.

string UUID [readonly]

UUID of the profile which the transport is for.

byte Codec [readonly]

Assigned number of codec that the transport support.

The values should match the profile specification which is indicated by the UUID.

array{byte} Configuration [readonly]

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

string State [readonly]

Indicates the state of the transport. Possible values are:

uint16 Delay [readwrite, optional]

Transport delay in 1/10 of millisecond, this property is only writeable when the transport corresponds to a sink endpoint and it was acquired by the sender.

uint16 Volume [readwrite, optional]

Indicates volume level of the transport, this property is only writeable when the transport was acquired by the sender.

Possible Values:

object Endpoint [readonly, optional, experimental]

Endpoint object which the transport is associated with.

uint32 Location [readonly, ISO only, experimental]

Indicates transport Audio Location.

array{byte} Metadata [readwrite, ISO Only, experimental]

Indicates transport Metadata.

array{object} Links [readonly, optional, CIS only, experimental]

Linked transport objects which the transport is associated with.

array{object} Links [readwrite, BIS only, experimental]

For a Broadcast Sink, the BIG sync procedure requires all desired streams to be enumerated from the start and it cannot be later reconfigured by adding or removing BISes.

To avoid terminating and recreating the BIG sync every time a new transport is selected for acquire, all transports selected via Select need to be linked together.

When the first transport is acquired via Transport.Acquire, all links are included in the BIG sync command.

An acquired transport will create and set fds for all its links. Then, each link needs to be acquired separately, to get the fd and start receiving audio.

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

Only present when QoS is configured.

Possible values for Broadcast:

Possible values for both Unicast and Broadcast:
