201da177e4SLinus Torvalds	  Bluetooth is low-cost, low-power, short-range wireless technology.
211da177e4SLinus Torvalds	  It was designed as a replacement for cables and other short-range
221da177e4SLinus Torvalds	  technologies like IrDA.  Bluetooth operates in personal area range
231da177e4SLinus Torvalds	  that typically extends up to 10 meters.  More information about
241da177e4SLinus Torvalds	  Bluetooth can be found at <http://www.bluetooth.com/>.
251da177e4SLinus Torvalds
261da177e4SLinus Torvalds	  Linux Bluetooth subsystem consist of several layers:
27f1e91e16SUlisses Furquim	     Bluetooth Core
28f1e91e16SUlisses Furquim		HCI device and connection manager, scheduler
29f1e91e16SUlisses Furquim		SCO audio links
30f1e91e16SUlisses Furquim		L2CAP (Logical Link Control and Adaptation Protocol)
31f1e91e16SUlisses Furquim		SMP (Security Manager Protocol) on LE (Low Energy) links
321da177e4SLinus Torvalds	     HCI Device drivers (Interface to the hardware)
331da177e4SLinus Torvalds	     RFCOMM Module (RFCOMM Protocol)
341da177e4SLinus Torvalds	     BNEP Module (Bluetooth Network Encapsulation Protocol)
351da177e4SLinus Torvalds	     CMTP Module (CAPI Message Transport Protocol)
361da177e4SLinus Torvalds	     HIDP Module (Human Interface Device Protocol)
371da177e4SLinus Torvalds
381da177e4SLinus Torvalds	  Say Y here to compile Bluetooth support into the kernel or say M to
391da177e4SLinus Torvalds	  compile it as module (bluetooth).
401da177e4SLinus Torvalds
411da177e4SLinus Torvalds	  To use Linux Bluetooth subsystem, you will need several user-space
42a0019bcaSGustavo F. Padovan	  utilities like hciconfig and bluetoothd.  These utilities and updates
43a0019bcaSGustavo F. Padovan	  to Bluetooth kernel modules are provided in the BlueZ packages.  For
44a0019bcaSGustavo F. Padovan	  more information, see <http://www.bluez.org/>.
