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:
Ulisses Furquimf1e91e12011-12-21 01:32:09 -020024 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
Linus Torvalds1da177e2005-04-16 15:20:36 -070029 HCI Device drivers (Interface to the hardware)
Linus Torvalds1da177e2005-04-16 15:20:36 -070030 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
Gustavo F. Padovana0019bc2011-02-07 19:15:43 -020039 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/>.

80 When the Bluetooth subsystem is built as module, then the test
81 cases are run first thing at module load time. When the Bluetooth
82 subsystem is compiled into the kernel image, then the test cases
83 are run late in the initcall hierarchy.
