BlueZ D-Bus Adapter API description *********************************** Copyright (C) 2004-2010 Marcel Holtmann Copyright (C) 2005-2006 Johan Hedberg Copyright (C) 2005-2006 Claudio Takahasi Copyright (C) 2006-2007 Luiz von Dentz 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.NotReady 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.InvalidArguments void RequestSession() This method requests a client session that provides operational Bluetooth. A possible mode change must be confirmed by the user via the agent. Clients may request multiple sessions. All sessions are released when adapter's mode is changed to off state. Possible Errors: org.bluez.Error.Rejected void ReleaseSession() Release a previously requested session. It sets adapter to the mode in use on the moment of session request. SetProperty method call changes adapter's mode persistently, such that session release will not modify it. 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() {deprecated} Returns list of device object paths. This method is deprecated, instead use the Devices Property to get the list of devices 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 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 sent 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 basically the same values that are returned by the GetProperties method from the org.bluez.Device interface. In addition there can be values for the RSSI, the TX power level and Broadcaster role. DeviceDisappeared(string address) This signal will be sent 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. uint32 Class [readonly] The Bluetooth class of device. 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 PaireableTimeout [readwrite] The pairable timeout in seconds. A value of zero means that the timeout is disabled and it will stay in pareable mode forever. 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. array{string} UUIDs [readonly] List of 128-bit UUIDs that represents the available local services.
