	  Bluetooth is low-cost, low-power, short-range wireless technology.
	  It was designed as a replacement for cables and other short-range
	  technologies like IrDA.  Bluetooth operates in personal area range
	  that typically extends up to 10 meters.  More information about
	  Bluetooth can be found at <https://www.bluetooth.com/>.

	  Linux Bluetooth subsystem consist of several layers:
	     Bluetooth Core
		HCI device and connection manager, scheduler
		SCO audio links
		L2CAP (Logical Link Control and Adaptation Protocol)
		SMP (Security Manager Protocol) on LE (Low Energy) links
		ISO isochronous links
	     HCI Device drivers (Interface to the hardware)
	     RFCOMM Module (RFCOMM Protocol)  
	     BNEP Module (Bluetooth Network Encapsulation Protocol)
	     HIDP Module (Human Interface Device Protocol)

	  Say Y here to compile Bluetooth support into the kernel or say M to
	  compile it as module (bluetooth).

	  To use Linux Bluetooth subsystem, you will need several user-space
	  utilities like hciconfig and bluetoothd.  These utilities and updates
	  to Bluetooth kernel modules are provided in the BlueZ packages.  For
	  more information, see <http://www.bluez.org/>.
