Bluetooth operates in personal area range 21 that typically extends up to 10 meters. More information about 22 Bluetooth can be found at <http://www.bluetooth.com/>. 23 24 Linux Bluetooth subsystem consist of several layers: 25 Bluetooth Core 26 HCI device and connection manager, scheduler 27 SCO audio links 28 L2CAP (Logical Link Control and Adaptation Protocol) 29 SMP (Security Manager Protocol) on LE (Low Energy) links 30 HCI Device drivers (Interface to the hardware) 31 RFCOMM Module (RFCOMM Protocol) 32 BNEP Module (Bluetooth Network Encapsulation Protocol) 33 CMTP Module (CAPI Message Transport Protocol) 34 HIDP Module (Human Interface Device Protocol) 35 36 Say Y here to compile Bluetooth support into the kernel or say M to 37 compile it as module (bluetooth). 38 39 To use Linux Bluetooth subsystem, you will need several user-space 40 utilities like hciconfig and bluetoothd. These utilities and updates 41 to Bluetooth kernel modules are provided in the BlueZ packages.
