Adapter hierarchy
=================
Service org.bluez
Interface org.bluez.Adapter
Object path [variable prefix]/{hci0,hci1,...}
Methods dict GetProperties()
Returns all properties for the adapter. See the
properties section for available properties.
Possible Errors: org.bluez.Error.DoesNotExist
org.bluez.Error.InvalidArguments
void SetProperty(string name, variant value)
Changes the value of the specified property. Only
properties that are listed a read-write are changeable.
On success this will emit a PropertyChanged signal.
Possible Errors: org.bluez.Error.DoesNotExist
org.bluez.Error.InvalidArguments
void RequestMode(string mode) {deprecated}
This method will request a mode change. The mode
change must be confirmed by the user via the agent.
Possible modes for this call are "connectable" and
"discoverable". Any application that wants to use
Bluetooth functionality can use this method to
indicate which mode it needs to operate sucessfully.
In case the user doesn't confirm the mode change it
will return an error to indicate this rejection.
Possible Errors: org.bluez.Error.DoesNotExist
org.bluez.Error.InvalidArguments
org.bluez.Error.Rejected
void ReleaseMode() {deprecated}
Releases a mode requested via RequestMode.
Possible Errors: org.bluez.Error.DoesNotExist
void RequestSession()
This method will request a client session that
provides operational Bluetooth. A possible mode
change must be confirmed by the user via the agent.
Possible Errors: org.bluez.Error.Rejected
void ReleaseSession()
Release a previous requested session.
Possible Errors: org.bluez.Error.DoesNotExist
void StartDiscovery()
This method starts the device discovery session. This
includes an inquiry procedure and remote device name
resolving. Use StopDiscovery to release the sessions
acquired.
This process will start emitting DeviceFound and
PropertyChanged "Discovering" signals.
Possible errors: org.bluez.Error.NotReady
org.bluez.Error.Failed
void StopDiscovery()
This method will cancel any previous StartDiscovery
transaction.
Note that a discovery procedure is shared between all
discovery sessions thus calling StopDiscovery will only
release a single session.
Possible errors: org.bluez.Error.NotReady
org.bluez.Error.Failed
org.bluez.Error.NotAuthorized
object FindDevice(string address)
Returns the object path of device for given address.
The device object needs to be first created via
CreateDevice or CreatePairedDevice.
Possible Errors: org.bluez.Error.DoesNotExist
org.bluez.Error.InvalidArguments
array{object} ListDevices()
Returns list of device object paths.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.Failed
org.bluez.Error.OutOfMemory
object CreateDevice(string address)
Creates a new object path for a remote device. This
method will connect to the remote device and retrieve
all SDP records.
If the object for the remote device already exists
this method will fail.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.Failed
object CreatePairedDevice(string address, object agent,
string capability)
Creates a new object path for a remote device. This
method will connect to the remote device and retrieve
all SDP records and then initiate the pairing.
If previously CreateDevice was used successfully,
this method will only initiate the pairing.
Compared to CreateDevice this method will fail if
the pairing already exists, but not if the object
path already has been created. This allows applications
to use CreateDevice first and the if needed use
CreatePairedDevice to initiate pairing.
The agent object path is assumed to reside within the
process (D-Bus connection instance) that calls this
method. No separate registration procedure is needed
for it and it gets automatically released once the
pairing operation is complete.
The capability parameter is the same as for the
RegisterAgent method.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.Failed
void CancelDeviceCreation(string address)
Aborts either a CreateDevice call or a
CreatePairedDevice call.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.NotInProgress
void RemoveDevice(object device)
This removes the remote device object at the given
path. It will remove also the pairing information.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.Failed
void RegisterAgent(object agent, string capability)
This registers the adapter wide agent.
The object path defines the path the of the agent
that will be called when user input is needed.
If an application disconnects from the bus all
of its registered agents will be removed.
The capability parameter can have the values
"DisplayOnly", "DisplayYesNo", "KeyboardOnly" and
"NoInputNoOutput" which reflects the input and output
capabilities of the agent. If an empty string is
used it will fallback to "DisplayYesNo".
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.AlreadyExists
void UnregisterAgent(object agent)
This unregisters the agent that has been previously
registered. The object path parameter must match the
same value that has been used on registration.
Possible errors: org.bluez.Error.DoesNotExist
Signals PropertyChanged(string name, variant value)
This signal indicates a changed value of the given
property.
DeviceFound(string address, dict values)
This signal will be send every time an inquiry result
has been found by the service daemon. In general they
only appear during a device discovery.
The dictionary can contain bascially the same values
that we be returned by the GetProperties method
from the org.bluez.Device interface. In addition there
can be values for the RSSI and the TX power level.
DeviceDisappeared(string address)
This signal will be send when an inquiry session for
a periodic discovery finishes and previously found
devices are no longer in range or visible.
DeviceCreated(object device)
Parameter is object path of created device.
DeviceRemoved(object device)
Parameter is object path of removed device.
Properties string Address [readonly]
The Bluetooth device address.
string Name [readwrite]
The Bluetooth friendly name. This value can be
changed and a PropertyChanged signal will be emitted.
string Mode [readwrite] {deprecated}
The Bluetooth operation mode.
Valid modes: "off", "connectable",
"discoverable", "limited"
This is deprecated by the Powered and Discoverable
properties.
boolean Powered [readwrite]
Switch an adapter on or off. This will also set the
appropiate connectable state.
boolean Discoverable [readwrite]
Switch an adapter to discoverable or non-discoverable
to either make it visible or hide it. This is a global
setting and should only be used by the settings
application.
If the DiscoverableTimeout is set to a non-zero
value then the system will set this value back to
false after the timer expired.
In case the adapter is switched off, setting this
value will fail.
When changing the Powered property the new state of
this property will be updated via a PropertyChanged
signal.
boolean Pairable [readwrite]
Switch an adapter to pairable or non-pairable. This is
a global setting and should only be used by the
settings application.
Note that this property only affects incoming pairing
requests.
uint32 DiscoverableTimeout [readwrite]
The discoverable timeout in seconds. A value of zero
means that the timeout is disabled and it will stay in
discoverable/limited mode forever.
The default value for the discoverable timeout should
be 180 seconds (3 minutes).
boolean Discovering [readonly]
Indicates that a device discovery procedure is active.
array{object} Devices [readonly]
List of device object paths.
