  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/>.

  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/>.

  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.
