| 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/>. |

| help |
| 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. |
