Control hierarchy
=================
Service org.bluez
Interface org.bluez.Control
Object path [variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX
Methods void Connect()
Connect to remote device (CT or TG).
void Disconnect()
Disconnect remote device.
dict GetProperties()
Returns all properties for the interface. See the
properties section for available properties.
void VolumeUp()
Adjust remote volume one step up
void VolumeDown()
Adjust remote volume one step down
boolean SendPassthrough(avc_operation_id key, boolean state,
string op_data)
Called to send Passthrough commands. ONLY valid if
BlueZ device is in CT role.
boolean SendVendorDependent(string op_data)
Called to send VendorDependent commands, other than
Metadata or Events defined in the AVRCP+Metadata
specification.
void ChangePlayback(string status, uint32 elapsed)
The status can be "playing", "stopped", "paused",
"forward-seek", "reverse-seek" or "error". Elapsed is
the position within the track in milliseconds.
void ChangeTrack(dict metadata)
Called to send the mandated TrackChange event and
potential metadata information.
Current defined metadata information are represented
with the following keys:
Title string (mandatory)
Artist string
Album string
Genre string
NumberOfTracks uint32
TrackNumber uint32
TrackDuration uint32 (in milliseconds)
void ChangeSetting(string setting, variant value)
Called to transmit Application Settings, CT Status
and the like.
Currenet defined settings are represented with the
following keys:
Equalizer off, on
Repeat off, singletrack, alltracks, group
Shuffle off, alltracks, group
Scan off, alltracks, group
Battery normal, warning, critical, external, fullcharge
System powered, unpowered, unplugged
Volume uint8
Signals Connected()
Sent when a successful AVRCP connection has been made
to the remote device.
Disconnected()
Sent when the AVRCP connection to the remote device
has been disconnected.
Passthrough(uint8 key, boolean state, int32 company_id,
string op_data)
Called when Passthrough command is received from
connected device.
NOTE: according to the AV/C Subpanel Spec, company_id
and op_data are passed ONLY when the key is
"Vendor_Unique", or 0x7E.
When the key is NOT 0x7E, the signal returns
company_id=-1, and zero-length op_data.
VendorDependentReceived(string op_data)
Called when VendorDependent message is received from
connected device (except for Metadata defined in
Bluetooth SIG AVRCP+Metadata spec).
TrackChanged(dict metadata)
Called when Metadata is received from connected device.
May be multiple meta attribute/element pairs.
PlaybackChanged(string status, uint32 elapsed)
SettingChanged(string setting, variant value)
Properties uint8 SubUnitID [readonly]
The three-bit Subunit ID from the connected device.
uint8 SubUnitType [readonly]
The five-bit Subunit Type from the connected device.
boolean Connected [readonly]
array{uint32} CompanyIDs [readonly]
List of three-byte Company IDs (OUI) supported by the
connected device. Note that Bluetooth SIG Company
ID (0x001958) is always included.
array{string} Capabilities [readonly]
List of Capabilities provided by the connected device.
