  	help
  	  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 <http://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

  	     HCI Device drivers (Interface to the hardware)

  	     RFCOMM Module (RFCOMM Protocol)  
  	     BNEP Module (Bluetooth Network Encapsulation Protocol)
  	     CMTP Module (CAPI Message Transport 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/>.

  config BT_BREDR

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

  	help
  	  Bluetooth High Speed includes support for off-loading
  	  Bluetooth connections via 802.11 (wifi) physical layer
  	  available with Bluetooth version 3.0 or later.

  	  Bluetooth Low Energy includes support low-energy physical
  	  layer available with Bluetooth version 4.0 or later.

  	  IPv6 compression over Bluetooth Low Energy.

  	help
  	  This option selects a few LED triggers for different
  	  Bluetooth events.

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

  config BT_SELFTEST_ECDH
  	bool "ECDH test cases"
  	depends on BT_LE && BT_SELFTEST
  	help
  	  Run test cases for ECDH cryptographic functionality used by the
  	  Bluetooth Low Energy Secure Connections feature.

  config BT_SELFTEST_SMP
  	bool "SMP test cases"
  	depends on BT_LE && BT_SELFTEST
  	help
  	  Run test cases for SMP cryptographic functionality, including both
  	  legacy SMP as well as the Secure Connections features.

  config BT_DEBUGFS
  	bool "Export Bluetooth internals in debugfs"
  	depends on BT && DEBUG_FS
  	default y
  	help
  	  Provide extensive information about internal Bluetooth states
  	  in debugfs.
