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 . 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.
