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

  39. L2CAP (Logical Link Control and Adaptation Protocol) provides
  40. connection oriented and connection-less data transport. L2CAP
  41. support is required for most Bluetooth applications.
  42. Also included is support for SMP (Security Manager Protocol) which
  43. is the security layer on top of LE (Low Energy) links.
  44. config BT_SCO

  46. help
  47. SCO link provides voice transport over Bluetooth. SCO support is
  48. required for voice applications like Headset and Audio.
