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

25 Linux Bluetooth subsystem consist of several layers:
26 Bluetooth Core
27 HCI device and connection manager, scheduler
28 SCO audio links
29 L2CAP (Logical Link Control and Adaptation Protocol)
30 SMP (Security Manager Protocol) on LE (Low Energy) links
31 HCI Device drivers (Interface to the hardware)
32 RFCOMM Module (RFCOMM Protocol)
33 BNEP Module (Bluetooth Network Encapsulation Protocol)
34 CMTP Module (CAPI Message Transport Protocol)
35 HIDP Module (Human Interface Device Protocol)
36
37 Say Y here to compile Bluetooth support into the kernel or say M to
38 compile it as module (bluetooth).
39
40 To use Linux Bluetooth subsystem, you will need several user-space
41 utilities like hciconfig and bluetoothd. These utilities and updates
42 to Bluetooth kernel modules are provided in the BlueZ packages. For
43 more information, see <http://www.bluez.org/>.

99 Run self tests when initializing the Bluetooth subsystem. This
100 is a developer option and can cause significant delay when booting
101 the system.

103 When the Bluetooth subsystem is built as module, then the test
104 cases are run first thing at module load time. When the Bluetooth
105 subsystem is compiled into the kernel image, then the test cases
106 are run late in the initcall hierarchy.
