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

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

122 Run self tests when initializing the Bluetooth subsystem. This
123 is a developer option and can cause significant delay when booting
124 the system.

126 When the Bluetooth subsystem is built as module, then the test
127 cases are run first thing at module load time. When the Bluetooth
128 subsystem is compiled into the kernel image, then the test cases
129 are run late in the initcall hierarchy.
