BlueZ D-Bus LE Advertising API Description
******************************************

Advertising packets are structured data which is broadcast on the LE Advertising
channels and available for all devices in range.  Because of the limited space
available in LE Advertising packets (31 bytes), each packet's contents must be
carefully controlled.

BlueZ acts as a store for the Advertisement Data which is meant to be sent.
It constructs the correct Advertisement Data from the structured
data and configured the kernel to send the correct advertisement.

Advertisement Data objects are registered freely and then referenced by BlueZ
when constructing the data sent to the kernel.

LE Advertisement Data hierarchy
===============================

Specifies the Advertisement Data to be broadcast and some advertising
parameters.  Properties which are not present will not be included in the
data.  Required advertisement data types will always be included.
All UUIDs are 128-bit versions in the API, and 16 or 32-bit
versions of the same UUID will be used in the advertising data as appropriate.

Service		org.bluez
Interface	org.bluez.LEAdvertisement1
Object path	freely definable

Methods		void Release() [noreply]

			This method gets called when the service daemon
			removes the Advertisement. A client can use it to do
			cleanup tasks. There is no need to call
			UnregisterAdvertisement because when this method gets
			called it has already been unregistered.

Properties	string Type

			Determines the type of advertising packet requested.

			Possible values: "broadcast" or "peripheral"

		array{string} ServiceUUIDs

			List of UUIDs to include in the "Service UUID" field of
			the Advertising Data.

		dict ManufacturerData

			Manufactuer Data fields to include in
			the Advertising Data.  Keys are the Manufacturer ID
			to associate with the data.

		array{string} SolicitUUIDs

			Array of UUIDs to include in "Service Solicitation"
			Advertisement Data.

		dict ServiceData

			Service Data elements to include. The keys are the
			UUID to associate with the data.

		dict Data [Experimental]

			Advertising Type to include in the Advertising
			Data. Key is the advertising type and value is the
			data as byte array.

			Note: Types already handled by other properties shall
			not be used.

			Possible values:
				<type> <byte array>
				...

			Example:
				<Transport Discovery> <Organization Flags...>
				0x26                   0x01         0x01...

		bool Discoverable [Experimental]

			Advertise as general discoverable. When present this
			will override adapter Discoverable property.

			Note: This property shall not be set when Type is set
			to broadcast.

		uint16 DiscoverableTimeout [Experimental]

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

			Note: This property shall not be set when Type is set
			to broadcast.

		array{string} Includes

			List of features to be included in the advertising
			packet.

			Possible values: as found on
					LEAdvertisingManager.SupportedIncludes

		string LocalName

			Local name to be used in the advertising report. If the
			string is too big to fit into the packet it will be
			truncated.

			If this property is available 'local-name' cannot be
			present in the Includes.

		uint16 Appearance

			Appearance to be used in the advertising report.

			Possible values: as found on GAP Service.

		uint16_t Duration

			Duration of the advertisement in seconds. If there are
			other applications advertising no duration is set the
			default is 2 seconds.

		uint16_t Timeout

			Timeout of the advertisement in seconds. This defines
			the lifetime of the advertisement.

		string SecondaryChannel [Experimental]

			Secondary channel to be used. Primary channel is
			always set to "1M" except when "Coded" is set.

			Possible value: "1M" (default)
					"2M"
					"Coded"

LE Advertising Manager hierarchy
================================

The Advertising Manager allows external applications to register Advertisement
Data which should be broadcast to devices.  Advertisement Data elements must
follow the API for LE Advertisement Data described above.

Service		org.bluez
Interface	org.bluez.LEAdvertisingManager1
Object path	/org/bluez/{hci0,hci1,...}

Methods		RegisterAdvertisement(object advertisement, dict options)

			Registers an advertisement object to be sent over the LE
			Advertising channel.  The service must be exported
			under interface LEAdvertisement1.

			InvalidArguments error indicates that the object has
			invalid or conflicting properties.

			InvalidLength error indicates that the data
			provided generates a data packet which is too long.

			The properties of this object are parsed when it is
			registered, and any changes are ignored.

			If the same object is registered twice it will result in
			an AlreadyExists error.

			If the maximum number of advertisement instances is
			reached it will result in NotPermitted error.

			Possible errors: org.bluez.Error.InvalidArguments
					 org.bluez.Error.AlreadyExists
					 org.bluez.Error.InvalidLength
					 org.bluez.Error.NotPermitted

		UnregisterAdvertisement(object advertisement)

			This unregisters an advertisement 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.InvalidArguments
					 org.bluez.Error.DoesNotExist

Properties	byte ActiveInstances

			Number of active advertising instances.

		byte SupportedInstances

			Number of available advertising instances.

		array{string} SupportedIncludes

			List of supported system includes.

			Possible values: "tx-power"
					 "appearance"
					 "local-name"

		array{string} SupportedSecondaryChannels [Experimental]

			List of supported Secondary channels. Secondary
			channels can be used to advertise with the
			corresponding PHY.

			Possible values: "1M"
					 "2M"
					 "Coded"
