Device hierarchy
================

Service		org.bluez
Interface	org.bluez.Device
Object path	/org/bluez/Device/{hci0,hci1,...}/

Methods		string GetAddress()

			Returns the device address for a given path.

			Example: "00:11:22:33:44:55"

		string GetVersion()

			Returns the version of the Bluetooth chip. This version
			is compiled from the LMP version. In case of EDR the
			features attribute must be checked.

			Example: "Bluetooth 2.0 + EDR"

		string GetRevision()

			Returns the revision of the Bluetooth chip. This is a
			vendor specific value and in most cases it represents
			the firmware version. This might derive from the HCI
			revision and LMP subversion values or via extra vendor
			specific commands.

			Example: "HCI 19.2"

		string GetManufacturer()

			Returns the manufacturer of the Bluetooth chip.

			Example: "Cambridge Silicon Radio"

		string GetCompany()

			Returns the company name from the OUI database of the
			Bluetooth device address. This function will need a
			valid and up-to-date oui.txt from the IEEE. This value
			will be different from the manufacturer string in the
			most cases.

			Example: "Apple Computer"

		array{string} GetFeatures()

			Returns list of features supported by the device. This
			list is only for showing them in the UI. No application
			should implement different behaviors based on these
			strings.

		string GetMode()

			Returns the current mode of a device.

			Valid modes: "off", "connectable", "discoverable"

		void SetMode(string mode)

			Sets mode of the device. See GetMode for valid strings
			for the mode parameter.

		uint32 GetDiscoverableTimeout()

			Returns the discoverable timeout in seconds. A value
			of zero means that the timeout is disabled and it will
			stay in discoverable mode forever.

			The default value for the discoverable timeout should
			be 180 seconds (3 minutes).

		void SetDiscoverableTimeout(uint32 timeout)

			Sets the discoverable timeout in seconds. A value of
			zero disables the timeout and the device would be
			always discoverable.

			Changing this value doesn't set the device into
			discoverable mode. The SetMode method must be used.

		boolean IsConnectable()

			Returns true if the local device is connectable and
			false if it is switched off.

			It is also possible to use GetMode to retrieve this
			information.

		boolean IsDiscoverable()

			Returns true if the local device is discoverable and
			false if it is only connectable or switched off.

			It is also possible to use GetMode to retrieve this
			information.

		string GetMajorClass()

			Returns the current major class value for this
			system. This value is set to "computer" for now.

		string GetMinorClass()

			Returns the current minor class value for this
			system where the default major class is "computer".

			Valid values: "uncategorized", "desktop", "server",
			              "laptop", "handheld", "palm", "wearable"

			The default value is "uncategorized".

		void SetMinorClass(string minor)

			Sets the local minor class and on success it sends
			a MinorClassChanged signal.

		array{string} GetServiceClasses()

			Returns the current set of service classes.

			Valid values: "positioning", "networking", "rendering",
			              "capturing", "object transfer", "audio",
			              "telephony", "information"

		string GetName()

			Returns the local device name (friendly name) in UTF-8.

		void SetName(string name)

			Sets the local device name. If EIR is supported by the
			local hardware this modifies also the extended response
			data value.

		string GetRemoteVersion(string address)

			Get the version info for a remote device. This request
			returns always this information based on its cached
			data. The base for this string is the LMP version
			value and the features for EDR support.

			Example: "Bluetooth 2.0 + EDR"

		string GetRemoteRevision(string address)

			Get the revision of the Bluetooth chip. This is a
			vendor specific value and in most cases it represents
			the firmware version. This derives only from the LMP
			subversion value.

			Example: "HCI 19.2"

		string GetRemoteManufacturer(string address)

			Get the manufacturer of the chip for a remote device.

			Example: "Nokia Mobile Phones"

		string GetRemoteCompany(string address)

			Get the company name from the OUI database of the
			Bluetooth device address. This function will need a
			valid and up-to-date oui.txt from the IEEE. This value
			will be different from the manufacturer string in the
			most cases.

			Example: "Microsoft Corporation"

		string GetRemoteName(string address)

			Get device name for a remote device. This request
			returns always a cached name. The service daemon is
			responsible for updating the cache.

			If this is an empty value, then no remote name
			available at the moment. The UI should show the
			address in this case.

			Example: "00:11:22:33:44:55", "Nokia 770"

		string GetRemoteAlias(string address)

			Returns alias name for remote device. If this is
			an empty value, then no alias has been defined so far.
			This is the default case and the UI should show the
			remote name instead.

			An alias should supersede the remote name.

		void SetRemoteAlias(string address, string alias)

			Sets alias name for remote device. If alias name is
			empty, then no alias is set.

			On success the SetRemoteAlias method will produce a
			RemoteAliasChanged signal which applications can use
			to update their current display of the remote device
			name.

		string LastSeen(string address)

			Returns the date and time when the device has been
			seen by a discover procedure.

			Example: "2006-02-08 12:00:00 GMT"

		string LastUsed(string address)

			Returns the date and time of the last time when the
			device has been connected.

			Example: "2006-02-08 12:00:00 GMT"

		void CreateBonding(string address)

			This method creates a bonding with a remote device.

			If a link key for this device already exists, this
			procedure should fail instead of trying to create a
			new pairing.

		void RemoveBonding(string address)

			This method removes the bonding with a remote device.

			For security reasons this includes removing the actual
			link key and also disconnecting any open connections
			for the remote device.

			If the link key was stored on the Bluetooth chip, it
			must be removed from there, too.

		boolean HasBonding(string address)

			Returns true if the remote device is bonded and false
			if no link key is available.

		array{string} ListBondings()

			List device addresses of currently bonded device.

		uint8 PinCodeLength(string address)

			Returns the PIN code length that was used in the
			pairing process.

		uint8 EncryptionKeySize(string address)

			Returns the currently used encryption key size.

			This method will fail if no connection to that device
			has been established.

Signals		void ModeChanged(string mode)

			If the current mode is changed with SetMode this signal
			will inform about the new mode.

			This signal can also be triggered by low-level HCI
			commands.

		void MinorClassChanged(string minor)

			After changing the minor class with SetMinorClass this
			signal will provide the new class value.

		void NameChanged(string name)

			After changing the local device name with SetName this
			signal will provide the new name.

			This signal can also be triggered by low-level HCI
			commands.

		void RemoteNameChanged(string address, string name)

			This signal will be send every time the service daemon
			detect a new name for a remote device.

		void RemoteAliasChanged(string address, string alias)

			After changing an alias with SetRemoteAlias this signal
			will indicate the new alias.

		void BondingCreated(string address)

			Signals that a successful bonding has been created.

		void BondingFailed(string address)

			Signals that a bonding has failed.

		void BondingRemoved(string address)

			Signals that a bonding was removed.
