+ Bluetooth is low-cost, low-power, short-range wireless technology.
+ It was designed as a replacement for cables and other short-range
+ technologies like IrDA. Bluetooth operates in personal area range
+ that typically extends up to 10 meters. More information about
+ Bluetooth can be found at <http://www.bluetooth.com/>.
+
+ Linux Bluetooth subsystem consist of several layers:
+ Bluetooth Core
+ HCI device and connection manager, scheduler
+ SCO audio links
+ L2CAP (Logical Link Control and Adaptation Protocol)
+ SMP (Security Manager Protocol) on LE (Low Energy) links
+ HCI Device drivers (Interface to the hardware)
+ RFCOMM Module (RFCOMM Protocol)
+ BNEP Module (Bluetooth Network Encapsulation Protocol)
+ CMTP Module (CAPI Message Transport Protocol)
+ HIDP Module (Human Interface Device Protocol)
+
+ Say Y here to compile Bluetooth support into the kernel or say M to
+ compile it as module (bluetooth).
+
+ To use Linux Bluetooth subsystem, you will need several user-space
+ utilities like hciconfig and bluetoothd. These utilities and updates
+ to Bluetooth kernel modules are provided in the BlueZ packages. For
+ more information, see <http://www.bluez.org/>.

+ Run self tests when initializing the Bluetooth subsystem. This

+ the system.

+ cases are run first thing at module load time. When the Bluetooth
+ subsystem is compiled into the kernel image, then the test cases
+ are run late in the initcall hierarchy.
