Adapter hierarchy
=================

Service		org.bluez
Interface	org.bluez.Adapter
Object path	[variable prefix]/{hci0,hci1,...}

Methods		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.

			Setting the powered or discoverable properties
			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 DevicesFound 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

		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",
			"NoInputNoOutput" and "KeyboardDisplay" 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		DevicesFound(array{object path, dict values})

			This signal will be sent every time devices have
			been found. In general they only appear during a
			device discovery.

			The dictionary contains the properties from the
			org.bluez.Device1 interface.

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
			appropriate 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 PairableTimeout [readwrite]

			The pairable timeout in seconds. A value of zero
			means that the timeout is disabled and it will stay in
			pairable 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{string} UUIDs [readonly]

			List of 128-bit UUIDs that represents the available
			local services.
