Methods
fd, uint16, uint16 Acquire()
Acquire transport file descriptor and the MTU for read and write respectively.
Possible Errors:
org.bluez.Error.NotAuthorized
org.bluez.Error.Failed
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:
org.bluez.Error.NotAuthorized
org.bluez.Error.Failed
org.bluez.Error.NotAvailable
void Release()
Releases file descriptor.
Properties
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:
- "idle"
not streaming
- "pending"
streaming but not acquired
- "active"
streaming and acquired
uint16 Delay [readwrite, optional]
Transport delay in 1/10 of millisecond, this property is only writeable when the transport 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: 0-127
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, ISO only, experimental]
Linked transport objects which the transport is associated with.
dict QoS [readonly, optional, ISO only, experimental]
Only present when QoS is configured.
