Mesh Network Hierarchy
======================
Service		org.bluez.mesh
Interface	org.bluez.mesh.Network1
Object path	/org/bluez/mesh

Methods:
	void Join(object app_root, array{byte}[16] uuid)

		This is the first method that an application has to call to
		become a provisioned node on a mesh network. The call will
		initiate broadcasting of Unprovisioned Device Beacon.

		The app_root parameter is a D-Bus object root path of
		the application that implements org.bluez.mesh.Application1
		interface. The application represents a node where child mesh
		elements have their own objects that implement
		org.bluez.mesh.Element1 interface. The application hierarchy
		also contains a provision agent object that implements
		org.bluez.mesh.ProvisionAgent1 interface. The standard
		DBus.ObjectManager interface must be available on the
		app_root path.

		The uuid parameter is a 16-byte array that contains Device UUID.
		This UUID must be unique (at least from the daemon perspective),
		therefore attempting to call this function using already
		registered UUID results in an error. The composition of the UUID
		octets must be in compliance with RFC 4122.

		When provisioning finishes, the daemon will call either
		JoinComplete or JoinFailed method on object implementing
		org.bluez.mesh.Application1 interface.

		PossibleErrors:
			org.bluez.mesh.Error.InvalidArguments
			org.bluez.mesh.Error.AlreadyExists,

	void Cancel(void)

		Cancels an outstanding provisioning request initiated by Join()
		method.

	object node, array{byte, array{(uint16, dict)}} configuration
			Attach(object app_root, uint64 token)

		This is the first method that an application must call to get
		access to mesh node functionalities.

		The app_root parameter is a D-Bus object root path of
		the application that implements org.bluez.mesh.Application1
		interface. The application represents a node where child mesh
		elements have their own objects that implement
		org.bluez.mesh.Element1 interface. The standard
		DBus.ObjectManager interface must be available on the
		app_root path.

		The token parameter is a 64-bit number that has been assigned to
		the application when it first got provisioned/joined mesh
		network, i.e. upon receiving JoinComplete() method. The daemon
		uses the token to verify whether the application is authorized
		to assume the mesh node identity.

		In case of success, the method call returns mesh node object
		(see Mesh Node Hierarchy section) and current configuration
		settings. The return value of configuration parameter is an
		array, where each entry is a structure that contains element
		configuration. The element configuration structure is organized
		as follows:

		byte

			Element index, identifies the element to which this
			configuration entry pertains.

		array{struct}

			Models array where each entry is a structure with the
			following members:

			uint16

				Either a SIG Model Identifier or, if Vendor key
				is present in model configuration dictionary, a
				16-bit vendor-assigned Model Identifier

			dict

				A dictionary that contains model configuration
				with the following keys defined:

				array{uint16} Bindings

					Indices of application keys bound to the
					model

				uint32 PublicationPeriod

					Model publication period in milliseconds

				uint16 Vendor

					A 16-bit Company ID as defined by the
					Bluetooth SIG

				array{variant} Subscriptions

					Addresses the model is subscribed to.

					Each address is provided either as
					uint16 for group addresses, or
					as array{byte} for virtual labels.

		PossibleErrors:
			org.bluez.mesh.Error.InvalidArguments
			org.bluez.mesh.Error.NotFound,
			org.bluez.mesh.Error.AlreadyExists,
			org.bluez.mesh.Error.Busy,
			org.bluez.mesh.Error.Failed

	void Leave(uint64 token)

		This removes the configuration information about the mesh node
		identified by the 64-bit token parameter. The token parameter
		has been obtained as a result of successful Join() method call.

		PossibleErrors:
			org.bluez.mesh.Error.InvalidArguments
			org.bluez.mesh.Error.NotFound
			org.bluez.mesh.Error.Busy

	void CreateNetwork(object app_root, array{byte}[16] uuid)

		This is the first method that an application calls to become
		a Provisioner node, and a Configuration Client on a newly
		created Mesh Network.

		The app_root parameter is a D-Bus object root path of the
		application that implements org.bluez.mesh.Application1
		interface, and a org.bluez.mesh.Provisioner1 interface. The
		application represents a node where child mesh elements have
		their own objects that implement org.bluez.mesh.Element1
		interface. The application hierarchy also contains a provision
		agent object that implements org.bluez.mesh.ProvisionAgent1
		interface. The standard DBus.ObjectManager interface must be
		available on the app_root path.

		The uuid parameter is a 16-byte array that contains Device UUID.
		This UUID must be unique (at least from the daemon perspective),
		therefore attempting to call this function using already
		registered UUID results in an error. The composition of the UUID
		octets must be in compliance with RFC 4122.

		The other information the bluetooth-meshd daemon will preserve
		about the initial node, is to give it the initial primary
		unicast address (0x0001), and create and assign a net_key as the
		primary network net_index (0x000).

		Upon successful processing of Create() method, the daemon
		will call JoinComplete method on object implementing
		org.bluez.mesh.Application1.

		PossibleErrors:
			org.bluez.mesh.Error.InvalidArguments
			org.bluez.mesh.Error.AlreadyExists,

	void Import(object app_root, array{byte}[16] uuid,
				array{byte}[16] dev_key,
				array{byte}[16] net_key, uint16 net_index,
				dict flags, uint32 iv_index, uint16 unicast)

		This method creates a local mesh node based on node
		configuration that has been generated outside bluetooth-meshd.

		The app_root parameter is a D-Bus object root path of the
		application that implements org.bluez.mesh.Application1
		interface.

		The uuid parameter is a 16-byte array that contains Device UUID.
		This UUID must be unique (at least from the daemon perspective),
		therefore attempting to call this function using already
		registered UUID results in an error. The composition of the UUID
		octets must be in compliance with RFC 4122.

		The dev_key parameter is the 16-byte value of the dev key of
		the imported mesh node.

		Remaining parameters correspond to provisioning data:

		The net_key and net_index parameters describe the network (or a
		subnet, if net_index is not 0) the imported mesh node belongs
		to.

		The flags parameter is a dictionary containing provisioning
		flags. Supported values are:

			boolean IvUpdate

				When true, indicates that the network is in the
				middle of IV Index Update procedure.

			boolean KeyRefresh

				When true, indicates that the specified net key
				is in the middle of a key refresh procedure.

		The iv_index parameter is the current IV Index value used by
		the network. This value is known by the provisioner.

		The unicast parameter is the primary unicast address of the
		imported node.

		Upon successful processing of Import() method, the daemon will
		call JoinComplete method on object implementing
		org.bluez.mesh.Application1 interface.

		PossibleErrors:
			org.bluez.mesh.Error.InvalidArguments,
			org.bluez.mesh.Error.AlreadyExists,
			org.bluez.mesh.Error.NotSupported,
			org.bluez.mesh.Error.Failed

Mesh Application Hierarchy
==========================
Service		unique name
Interface	org.bluez.mesh.Application1
Object path	<app_root>

An application is a collection of elements that host SIG defined and vendor
specific models. It is expected that an application implements
org.freedesktop.DBus.ObjectManager interface at app_root path.

An example mesh application hierarchy may look like this:

-> /com/example
  |   - org.freedesktop.DBus.ObjectManager
  |
  -> /com/example/application
  |   - org.bluez.mesh.Application1
  |   - org.bluez.mesh.Attention1 (optional)
  |   - org.bluez.mesh.Provisioner1 (optional,Provisioner)
  |
  -> /com/example/agent
  |   - org.bluez.mesh.ProvisionAgent1
  |
  -> /com/example/ele00
  |   - org.bluez.mesh.Element1
  |
  -> /com/example/ele01
  |   - org.bluez.mesh.Element1
  |
  ...
  -> /com/example/elexx
      - org.bluez.mesh.Element1

Methods:
	void JoinComplete(uint64 token)

		This method is called when the node provisioning initiated
		by a Join() method call successfully completed.

		The token parameter serves as a unique identifier of the
		particular node. The token must be preserved by the application
		in order to authenticate itself to the mesh daemon and attach to
		the network as a mesh node by calling Attach() method or
		permanently remove the identity of the mesh node by calling
		Leave() method.

		If this method returns an error, the daemon will assume that the
		application failed to preserve the token, and will remove the
		freshly created node.

	void JoinFailed(string reason)

		This method is called when the node provisioning initiated by
		Join() has failed.

		The reason parameter identifies the reason for provisioning
		failure. The defined values are: "timeout", "bad-pdu",
		"confirmation-failed", "out-of-resources", "decryption-error",

		used to decode the incoming message. The same key_index should
		be used by the application when sending a response to this
		message (in case a response is expected).

		The destination parameter contains the destination address of
		received message. Underlying variant types are:

		uint16

			Destination is an unicast address, or a well known

		node's device key.

		The source parameter is unicast address of the remote
		node-element that sent the message.

		The remote parameter if true indicates that the device key
		used to decrypt the message was from the sender. False
		indicates that the local nodes device key was used, and the
		message has permissions to modify local states.

		uint16 Server
			Specifies the remote server that received the
			Unprovisioned beacon. If not present, beacon was
			received locally.

		uint8 array ExtendedData
			If Extended data was requested during scanning, any
			received data will be returned here.

		If a beacon with a UUID that has already been reported is
		received by the daemon, it will be silently discarded unless it
		was received at a higher rssi power level.

		This method is called during provisioning if the local device is
		the Provisioner, and is requestng Out-Of-Band ECC key exchange.
		The Public key is returned to the Daemon that is the matched
		pair of the Private key of the remote device. The Public Key
		returned must be 64 octets in size, or the Provisioning
		procedure will fail and be canceled.

		This function will only be called if the Provisioner has
		requested pre-determined keys to be exchanged Out-of-Band, and
		the local role is Provisioner.
