Marcel, Johan, Brad, et al:
As promised, I have laid out a first draft interface for .control, which is
largely based on AVRCP support provided by CSR.
It appears that the *-api.txt documents are created with groff (or something
like that); this document I just quickly hacked together in KWrite (similar
to MS Notepad).
Any and all comments will be appreciated.

Frequency One
org.bluez.audio.Control interface
This interface is available for remote devices which implement support for an
AVRCP controller and target.
Object path(s) /org/bluez/audio/device*
Methods:
void Connect(uint8 role)
Request connection between this node and remote device.
Role is role of THIS node in the connection, {CT|TG|CT&TG}.
void Disconnect()
Disconnect from the remote device.
boolean IsConnected()
Returns TRUE if connected with the remote device.
boolean GetUnitInfo()
Sends UnitInfo command to target of connection
boolean SendUnitInfo(boolean accepted,
uint8 avc_subunit_type, uint16 unit, uint32 company_id)
Called to send UnitInfo (in response to a UnitInfoRequested signal).
NOTE: Once this is set, should it be possible to auto-respond to
future UnitInfoRequested signals?
boolean GetSubUnitInfo(uint8 page)
Sends UnitInfo command to target of connection
boolean SendSubUnitInfo(boolean accepted, uint8 page,
const uint8 * page_data)
Called to send a page of SubUnitInfo (in response to a
SubUnitInfoRequested signal).
boolean SendPassthrough(uint8 avc_subunit_type,
uint8 avc_subunit_id, boolean state, avc_operation_id key,
uint16 sizeof_op_data, const uint8 * op_data)
Called to send Passthrough commands.
boolean SendVendorDependent(uint8 avc_subunit_type,
uint8 avc_subunit_id, uint8 ctype, uint32 company_id,
uint16 sizeof_op_data, const uint8 * op_data)
Called to send VendorDependent commands (also used internally for
Metadata).
void SendMetadata(uint8 avc_subunit_type,
uint8 avc_subunit_id, uint8 ctype,
{uint16 meta_attr, const char * meta_element})
Called to send Metadata commands (a subset of the
VendorDependent message). May be multiple meta attribute/element pairs.
Signals:
void Connected()
Sent when a successful connection has been made to the remote device.
void Disconnected()
Sent when a connection to the remote device has been disconnected.
void ConnectRequested(string address, uint8 role)
Sent when a remote device wishes to connect.
void DisconnectRequested()
Sent when a connected remote device wishes to disconnect.
void UnitInfoRequested()
Received when another connected device requests UnitInfo.
void UnitInfoReceived(boolean accepted,
uint8 avc_subunit_type, uint16 unit, uint32 company_id)
Called when response to GetUnitInfo is received from connected
device.
void SubUnitInfoRequested(uint8 page)
Received when another connected device requests SubUnitInfo
void SubUnitInfoReceived(boolean accepted, uint8 page,
const uint8 * page_data)
Called when response to GetSubUnitInfo is received from connected device.
void PassthroughReceived(uint8 avc_subunit_type,
uint8 avc_subunit_id, boolean state, avc_operation_id key,
uint16 sizeof_op_data, const uint8 * op_data)
Called when Passthrough command is received from connected device.
void VendorDependentReceived(uint8 avc_subunit_type,
uint8 avc_subunit_id, uint8 ctype, uint32 company_id,
uint16 sizeof_op_data, const uint8 * op_data)
Called when VendorDependent message is received from connected device
(except for Metadata).
void MetadataReceived(uint8 avc_subunit_type,
uint8 avc_subunit_id, uint8 ctype,
{uint16 meta_attr, const char * meta_element})
Called when Metadata is received from connected device. May be multiple
meta attribute/element pairs.
