1# 2# Bluetooth subsystem configuration 3# 4 5menuconfig BT 6 tristate "Bluetooth subsystem support" 7 depends on NET && !S390 8 depends on RFKILL || !RFKILL 9 help 10 Bluetooth is low-cost, low-power, short-range wireless technology. 11 It was designed as a replacement for cables and other short-range 12 technologies like IrDA. Bluetooth operates in personal area range 13 that typically extends up to 10 meters. More information about 14 Bluetooth can be found at <http://www.bluetooth.com/>. 15 16 Linux Bluetooth subsystem consist of several layers: 17 Bluetooth Core (HCI device and connection manager, scheduler) 18 HCI Device drivers (Interface to the hardware) 19 SCO Module (SCO audio links) 20 L2CAP Module (Logical Link Control and Adaptation Protocol) 21 RFCOMM Module (RFCOMM Protocol) 22 BNEP Module (Bluetooth Network Encapsulation Protocol) 23 CMTP Module (CAPI Message Transport Protocol) 24 HIDP Module (Human Interface Device Protocol) 25 SMP Module (Security Manager Protocol) 26 27 Say Y here to compile Bluetooth support into the kernel or say M to 28 compile it as module (bluetooth). 29 30 To use Linux Bluetooth subsystem, you will need several user-space 31 utilities like hciconfig and bluetoothd. These utilities and updates 32 to Bluetooth kernel modules are provided in the BlueZ packages. For 33 more information, see <http://www.bluez.org/>. 34 35if BT != n 36 37config BT_L2CAP 38 bool "L2CAP protocol support" 39 select CRC16 40 select CRYPTO 41 select CRYPTO_BLKCIPHER 42 select CRYPTO_AES 43 select CRYPTO_ECB 44 help 45 L2CAP (Logical Link Control and Adaptation Protocol) provides 46 connection oriented and connection-less data transport. L2CAP 47 support is required for most Bluetooth applications. 48 49 Also included is support for SMP (Security Manager Protocol) which 50 is the security layer on top of LE (Low Energy) links. 51 52config BT_SCO 53 bool "SCO links support" 54 help 55 SCO link provides voice transport over Bluetooth. SCO support is 56 required for voice applications like Headset and Audio. 57 58endif 59 60source "net/bluetooth/rfcomm/Kconfig" 61 62source "net/bluetooth/bnep/Kconfig" 63 64source "net/bluetooth/cmtp/Kconfig" 65 66source "net/bluetooth/hidp/Kconfig" 67 68source "drivers/bluetooth/Kconfig" 69 70
