 17	  Bluetooth is low-cost, low-power, short-range wireless technology.
 18	  It was designed as a replacement for cables and other short-range
 19	  technologies like IrDA.  Bluetooth operates in personal area range
 20	  that typically extends up to 10 meters.  More information about
 21	  Bluetooth can be found at <http://www.bluetooth.com/>.
 22
 23	  Linux Bluetooth subsystem consist of several layers:
 24	     Bluetooth Core
 25		HCI device and connection manager, scheduler
 26		SCO audio links
 27		L2CAP (Logical Link Control and Adaptation Protocol)
 28		SMP (Security Manager Protocol) on LE (Low Energy) links
 29	     HCI Device drivers (Interface to the hardware)
 30	     RFCOMM Module (RFCOMM Protocol)  
 31	     BNEP Module (Bluetooth Network Encapsulation Protocol)
 32	     CMTP Module (CAPI Message Transport Protocol)
 33	     HIDP Module (Human Interface Device Protocol)
 34
 35	  Say Y here to compile Bluetooth support into the kernel or say M to
 36	  compile it as module (bluetooth).
 37
 38	  To use Linux Bluetooth subsystem, you will need several user-space
 39	  utilities like hciconfig and bluetoothd.  These utilities and updates
 40	  to Bluetooth kernel modules are provided in the BlueZ packages.  For
 41	  more information, see <http://www.bluez.org/>.

 84	help
 85	  Run self tests when initializing the Bluetooth subsystem.  This
 86	  is a developer option and can cause significant delay when booting
 87	  the system.
 88
 89	  When the Bluetooth subsystem is built as module, then the test
 90	  cases are run first thing at module load time.  When the Bluetooth
 91	  subsystem is compiled into the kernel image, then the test cases
 92	  are run late in the initcall hierarchy.
