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/>.
