  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/>.

  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/>.

  90           When the Bluetooth subsystem is built as module, then the test
  91           cases are run first thing at module load time.  When the Bluetooth
  92           subsystem is compiled into the kernel image, then the test cases
  93           are run late in the initcall hierarchy.
