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/>. | |
23 | ||
24 | Linux Bluetooth subsystem consist of several layers: | |
f1e91e16 UF |
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 | |
1da177e4 | 30 | HCI Device drivers (Interface to the hardware) |
1da177e4 LT |
31 | RFCOMM Module (RFCOMM Protocol) |
32 | BNEP Module (Bluetooth Network Encapsulation Protocol) | |
33 | CMTP Module (CAPI Message Transport Protocol) | |
34 | HIDP Module (Human Interface Device Protocol) | |
35 | ||
36 | Say Y here to compile Bluetooth support into the kernel or say M to | |
37 | compile it as module (bluetooth). | |
38 | ||
39 | To use Linux Bluetooth subsystem, you will need several user-space | |
a0019bca GP |
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/>. | |

98 | Run self tests when initializing the Bluetooth subsystem. This | |
99 | is a developer option and can cause significant delay when booting | |
100 | the system. | |
101 | ||
102 | When the Bluetooth subsystem is built as module, then the test | |
103 | cases are run first thing at module load time. When the Bluetooth | |
104 | subsystem is compiled into the kernel image, then the test cases | |
105 | are run late in the initcall hierarchy. | |
