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

24 Linux Bluetooth subsystem consist of several layers:
Ulisses Furquimf1e91e12011-12-21 01:32:09 -0200[diff] [blame]25 Bluetooth Core
26 HCI device and connection manager, scheduler
27 SCO audio links
28 L2CAP (Logical Link Control and Adaptation Protocol)
29 SMP (Security Manager Protocol) on LE (Low Energy) links

33 CMTP Module (CAPI Message Transport Protocol)
34 HIDP Module (Human Interface Device Protocol)

36 Say Y here to compile Bluetooth support into the kernel or say M to
37 compile it as module (bluetooth).

39 To use Linux Bluetooth subsystem, you will need several user-space
Gustavo F. Padovana0019bc2011-02-07 19:15:43 -0200[diff] [blame]40 utilities like hciconfig and bluetoothd. These utilities and updates
41 to Bluetooth kernel modules are provided in the BlueZ packages. For
42 more information, see <http://www.bluez.org/>.

90 When the Bluetooth subsystem is built as module, then the test
91 cases are run first thing at module load time. When the Bluetooth
92 subsystem is compiled into the kernel image, then the test cases
93 are run late in the initcall hierarchy.
