11 Bluetooth is low-cost, low-power, short-range wireless technology.
12 It was designed as a replacement for cables and other short-range
13 technologies like IrDA. Bluetooth operates in personal area range
14 that typically extends up to 10 meters. More information about
15 Bluetooth can be found at <http://www.bluetooth.com/>.

17 Linux Bluetooth subsystem consist of several layers:
18 Bluetooth Core (HCI device and connection manager, scheduler)
19 HCI Device drivers (Interface to the hardware)
20 SCO Module (SCO audio links)
21 L2CAP Module (Logical Link Control and Adaptation Protocol)
22 RFCOMM Module (RFCOMM Protocol)
23 BNEP Module (Bluetooth Network Encapsulation Protocol)
24 CMTP Module (CAPI Message Transport Protocol)
25 HIDP Module (Human Interface Device Protocol)
Vinicius Costa Gomes3a0259b2011-06-09 18:50:43 -030026 SMP Module (Security Manager Protocol)
Linus Torvalds1da177e2005-04-16 15:20:36 -070027
28 Say Y here to compile Bluetooth support into the kernel or say M to
29 compile it as module (bluetooth).

31 To use Linux Bluetooth subsystem, you will need several user-space
Gustavo F. Padovana0019bc2011-02-07 19:15:43 -020032 utilities like hciconfig and bluetoothd. These utilities and updates
33 to Bluetooth kernel modules are provided in the BlueZ packages. For
34 more information, see <http://www.bluez.org/>.

46 L2CAP (Logical Link Control and Adaptation Protocol) provides
47 connection oriented and connection-less data transport. L2CAP
48 support is required for most Bluetooth applications.
49
Vinicius Costa Gomes3a0259b2011-06-09 18:50:43 -030050 Also included is support for SMP (Security Manager Protocol) which
51 is the security layer on top of LE (Low Energy) links.
