# # Bluetooth subsystem configuration # menuconfig BT tristate "Bluetooth subsystem support" depends on NET && !S390 depends on RFKILL || !RFKILL select CRYPTO 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) SCO Module (SCO audio links) L2CAP Module (Logical Link Control and Adaptation Protocol) RFCOMM Module (RFCOMM Protocol) BNEP Module (Bluetooth Network Encapsulation Protocol) CMTP Module (CAPI Message Transport Protocol) HIDP Module (Human Interface Device Protocol) SMP Module (Security Manager 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. For more information, see . if BT != n config BT_L2CAP bool "L2CAP protocol support" select CRC16 select CRYPTO select CRYPTO_BLKCIPHER select CRYPTO_AES select CRYPTO_ECB help L2CAP (Logical Link Control and Adaptation Protocol) provides connection oriented and connection-less data transport. L2CAP support is required for most Bluetooth applications. Also included is support for SMP (Security Manager Protocol) which is the security layer on top of LE (Low Energy) links. config BT_SCO bool "SCO links support" help SCO link provides voice transport over Bluetooth. SCO support is required for voice applications like Headset and Audio. endif source "net/bluetooth/rfcomm/Kconfig" source "net/bluetooth/bnep/Kconfig" source "net/bluetooth/cmtp/Kconfig" source "net/bluetooth/hidp/Kconfig" source "drivers/bluetooth/Kconfig"
