- 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
- is a developer option and can cause significant delay when booting
- the system.
- When the Bluetooth subsystem is built as module, then the test
- 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.
