# # Bluetooth subsystem configuration # menuconfig BT depends on NET tristate "Bluetooth subsystem support" help 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 . Linux Bluetooth subsystem consist of several layers: Bluetooth Core (HCI device and connection manager, scheduler) HCI Device drivers (interface to the hardware) L2CAP Module (L2CAP protocol) SCO Module (SCO links) RFCOMM Module (RFCOMM protocol) BNEP Module (BNEP protocol) CMTP Module (CMTP protocol) Say Y here to enable Linux Bluetooth support and to build Bluetooth Core layer. To use Linux Bluetooth subsystem, you will need several user-space utilities like hciconfig and hcid. These utilities and updates to Bluetooth kernel modules are provided in the BlueZ packages. For more information, see . If you want to compile Bluetooth Core as module (bluetooth) say M here. config BT_L2CAP tristate "L2CAP protocol support" depends on BT help L2CAP (Logical Link Control and Adaptation Protocol) provides connection oriented and connection-less data transport. L2CAP support is required for most Bluetooth applications. Say Y here to compile L2CAP support into the kernel or say M to compile it as module (l2cap). config BT_SCO tristate "SCO links support" depends on BT help SCO link provides voice transport over Bluetooth. SCO support is required for voice applications like Headset and Audio. Say Y here to compile SCO support into the kernel or say M to compile it as module (sco). source "net/bluetooth/rfcomm/Kconfig" source "net/bluetooth/bnep/Kconfig" source "net/bluetooth/cmtp/Kconfig" source "drivers/bluetooth/Kconfig"
