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

48	help
49	  Bluetooth Classic includes support for Basic Rate (BR)
50	  available with Bluetooth version 1.0b or later and support
51	  for Enhanced Data Rate (EDR) available with Bluetooth
52	  version 2.0 or later.

95	bool "Bluetooth self testing support"
96	depends on BT && DEBUG_KERNEL
97	help
98	  Run self tests when initializing the Bluetooth subsystem.  This
99	  is a developer option and can cause significant delay when booting
100	  the system.
101
102	  When the Bluetooth subsystem is built as module, then the test
103	  cases are run first thing at module load time.  When the Bluetooth
104	  subsystem is compiled into the kernel image, then the test cases
105	  are run late in the initcall hierarchy.

116	depends on BT_LE && BT_SELFTEST
117	help

119	  legacy SMP as well as the Secure Connections features.

127	  in debugfs.
