H A DKconfig3 # Bluetooth subsystem configuration
7 tristate "Bluetooth subsystem support"
16 Bluetooth is low-cost, low-power, short-range wireless technology.
18 technologies like IrDA. Bluetooth operates in personal area range
20 Bluetooth can be found at <https://www.bluetooth.com/>.
22 Linux Bluetooth subsystem consist of several layers:
23 Bluetooth Core
31 BNEP Module (Bluetooth Network Encapsulation Protocol)
34 Say Y here to compile Bluetooth support into the kernel or say M to
35 compile it as module (bluetooth).
