Constant definitions
====================

The class of device definition from the Bluetooth specification divides into
three different parts. It the major class, the minor class and the service
classes. The D-Bus interface will always use string constants to identify
any of these classes.

Service classes		positioning, networking, rendering, capturing,
			object transfer, audio, telephony, information

Major classes		miscellaneous, computer, phone, access point,
			audio/video, peripheral, imaging, wearable, toy,
			uncategorized

Minor classes computer	uncategorized, desktop, server, laptop, handheld,
			palm, wearable

Minor classes phone	uncategorized, cellular, cordless, smart phone,
			modem, isdn

Minor classes access point	fully, 1-17 percent, 17-33 percent,
			33-50 percent, 50-67 percent, 67-83 percent,
			83-99 percent, not available

Minor classes audio video	uncategorized, headset, handsfree,microphone,
			loudspeaker, headphones, portable audio, car audio,
			set-top box, hifi audio, vcr, video camera, camcorder,
			video monitor, video display and loudspeaker,
			video conferencing, gaming/toy, unknown

Error hierarchy
===============

Interface	org.bluez.Error

Errors		Failed

			An unknown error occured. The error messages is
			taken from the strerror(errno) function.

		InvalidArguments

			Error returned when the argument list is invalid or
			out of specification for the method.

		NotAuthorized

			Error returned when the caller of a method is not
			authorized. This might happen if a caller tries to
			terminate a connection that it hasn't created.

		OutOfMemory

			Error returned when a memory allocation via malloc()
			fails. This error is similar to ENOMEM.

		NoSuchAdapter

			Error returned when the requested adapter doesn't
			exists. This error is similar to ENODEV.

		NotReady

			Error returned when the adapter is DOWN.

		NotAvailable

			Error returned when a specified record is not
			available.

		NotConnected

			Error returned when the remote device isn't connected
			at the moment.

		ConnectionAttemptFailed

		AlreadyExists

			Error returned if a record for a specific procedure
			already exists and it has been tried create a new
			one. The error message however should indicate the
			procedure that fails. For example "Bonding already
			exists"

		DoesNotExist

			Error returned if a record for a specifc procedure
			doesn't exist. The error message however should
			indicate the procedure that fails. For example
			"Bonding does not exist".

		InProgress

			Error returned if an operation is in progress. Since
			this is a generic error that can be used in various
			situations, the error message should be more clear
			about what is in progress. For example "Bonding in
			progress".

Security hierarchy
==================

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

Methods		void RegisterDefaultPasskeyAgent(string path)

			This registers the default passkey agent. It can
			register a passkey for all adapters or for a
			specific device depending on with object path has
			been used.

			The path parameter defines the object path of the
			passkey agent that will be called when a passkey

		void RegisterPasskeyAgent(string path, string address)

			This registers the application passkey agent that
			will be used for any application specific passkey
			tasks.

			The path parameter defines the object path of the
			passkey agent that will be called when a passkey
			needs to be entered. The address defines the remote
			device that it will answer passkey requests for.

			If an application disconnects from the bus all
			registered passkey agent will be removed. It will
			also be unregistered after a timeout and if the
			pairing succeeds or fails. The application has to
			take care of that it reregisters the passkey agent.

			Possible errors: org.bluez.Error.AlreadyExists

		void UnregisterPasskeyAgent(string path, string address)

			This unregisters a passkey agent that has been
			previously registered. The object path and the path
			and address parameter must match the same values
			that has been used on registration.

			The method is actually only needed if an application
			wants to removed the passkey agent and don't wanna
			wait for the automatic timeout.

			Possible errors: org.bluez.Error.DoesNotExist

		void RegisterDefaultAuthorizationAgent(string path) [experimental]

			This registers the default authorization agent. It can
			register an authorization agent for all adapters or
			for a specific one depending on which object path has
			been used.

			The path parameter defines the object path of the
			authorization agent that will be called when an
			authorization request needs to be answered.

		void UnregisterDefaultAuthorizationAgent(string path) [experimental]

			This unregisters a default authorization agent that has
			been previously registered. The path parameter must
			match the same value that has been used on
			registration.


PasskeyAgent hierarchy
======================

Service		unique name
Interface	org.bluez.PasskeyAgent
Object path	freely definable

Methods		string Request(string path, string address, boolean numeric)

			This method gets called when the service daemon
			needs to get the passkey for an authentication. The
			return value is actual passkey.

			The first argument contains the path of the local
			adapter and the second one the remote address. The
			third argument signals if a numeric PIN code is
			expected or not. The default is a 1 to 16 byte PIN
			code in UTF-8 format.

			Possible errors: org.bluez.Error.Rejected
			                 org.bluez.Error.Canceled

		void Confirm(string path, string address, string value)

			This method gets called when the service daemon
			needs to verify a passkey. The verification is
			done by showing the value to the passkey agent
			and returning means a successful confirmation.
			In case the values don't match an error must
			be returned.

			Possible errors: org.bluez.Error.Rejected
			                 org.bluez.Error.Canceled

		void Display(string path, string address, string value)

			This method gets called when the service daemon
			needs to display the passkey value. No return
			value is needed. A successful paring will be
			indicated by the Complete method and a failure
			will be signaled with Cancel.

		void Keypress(string path, string address)

			This method indicates keypresses from the remote
			device. This can happen when pairing with a keyboard.

		void Complete(string path, string address)

			This method gets called to indicate that the
			authentication has been completed.

		void Cancel(string path, string address)

			This method gets called to indicate that the
			authentication request failed before a reply was
			returned by the Request method.

		void Release()

			This method gets called when the service daemon
			unregisters a passkey agent. An agent can use
			it to do cleanup tasks. There is no need to
			unregister the agent, because when this method
			gets called it has already been unregistered.


AuthorizationAgent hierarchy (experimental)
===========================================

Service		unique name
Interface	org.bluez.AuthorizationAgent
Object path	freely definable

Methods		void Authorize(string adapter_path, string address,
					string service_path, string uuid)

			This method gets called when the service daemon wants
			to get an authorization for accessing a service. This
			method should return if the remote user is granted
			access or an error otherwise.

			The adapter_path parameter is the object path of the
			local adapter. The address, service_path and action
			parameters correspond to the remote device address,
			the object path of the service and the uuid of the
			profile.

			Possible errors: org.bluez.Error.Rejected
			                 org.bluez.Error.Canceled

		void Cancel(string adapter_path, string address,
					string service_path, string uuid)

			This method cancels a previous authorization request.
			The adapter_path, address, service_path and uuid
			parameters must match the same values that have been
			used when the Authorize() method was called.

		void Release()

			This method gets called when the service daemon
			unregisters an authorization agent. An agent can
			use it to do cleanup tasks. There is no need to
			unregister the agent, because when this method
			gets called it has already been unregistered.


RFCOMM hierarchy (experimental)
===============================

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

Methods		string Connect(string address, string service)

			This creates a connection to a remote RFCOMM based
			service. The service string can either be a UUID-128,
			a service abbreviation or a record handle.

			The return value will be the path of the newly
			created RFCOMM TTY device (for example /dev/rfcomm0).

			If the application disconnects from the D-Bus this
			connection will be terminated.

			Valid service values: "vcp", "map", "pbap", "sap",
			                      "ftp", "bpp", "bip", "synch",
			                      "dun", "opp", "fax", "spp"

		void CancelConnect(string address, string service)

			This method cancels a previous Connect method call.

		string ConnectByChannel(string address, byte channel)

			This creates a connection to a remote RFCOMM based
			service. In contrast to Connect a channel number is
			needed.

			The return value will be the path of the newly
			creates RFCOMM TTY device (for example /dev/rfcomm0).

			If the application disconnects from the D-Bus this
			connection will be terminated.

		void CancelConnectByChannel(string address, byte channel)

			This method cancels a previous ConnectByChannel
			method call.

		void Disconnect(string device)

			This will disconnect a previously connected RFCOMM
			service. The device parameter must be the return value
			from a previous Connect or ConnectByChannel method
			call (for example /dev/rfcomm0).

		string Bind(string address, string service)

		string BindByChannel(string address, byte channel)

		void Release(string device)

		array{string} ListBindings()
