Object path	[variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX

Methods:

	Boolean Echo()

		response matches with the buffer sent. If some error is detected
		False value is returned.

		Possible errors: org.bluez.Error.InvalidArguments
				org.bluez.Error.OutOfRange

	object CreateChannel(object application, string configuration)

		Creates a new data channel.
		The configuration should indicate the channel quality of

		Possible errors: org.bluez.Error.InvalidArguments
				org.bluez.Error.NotFound
				org.bluez.Error.NotAllowed

Signals:

	void ChannelConnected(object channel)

		This signal is launched when a new data channel is created or
		when a known data channel is reconnected.

	void ChannelDeleted(object channel)

		This signal is launched when a data channel is deleted.

		After this signal the data channel path will not be valid and
		its path can be reused for future data channels.

	void PropertyChanged(string name, variant value)

		This signal indicates a changed value of the given property.

Properties:

	object MainChannel [readonly]

		The first reliable channel opened. It is needed by upper
		applications in order to send specific protocol data units. The
		first reliable can change after a reconnection.
