Bluetooth operates in personal area range 20 that typically extends up to 10 meters. More information about 21 Bluetooth can be found at <http://www.bluetooth.com/>. 22 23 Linux Bluetooth subsystem consist of several layers: 24 Bluetooth Core 25 HCI device and connection manager, scheduler 26 SCO audio links 27 L2CAP (Logical Link Control and Adaptation Protocol) 28 SMP (Security Manager Protocol) on LE (Low Energy) links 29 HCI Device drivers (Interface to the hardware) 30 RFCOMM Module (RFCOMM Protocol) 31 BNEP Module (Bluetooth Network Encapsulation Protocol) 32 CMTP Module (CAPI Message Transport Protocol) 33 HIDP Module (Human Interface Device Protocol) 34 35 Say Y here to compile Bluetooth support into the kernel or say M to 36 compile it as module (bluetooth). 37 38 To use Linux Bluetooth subsystem, you will need several user-space 39 utilities like hciconfig and bluetoothd. These utilities and updates 40 to Bluetooth kernel modules are provided in the BlueZ packages.
