Bluetooth operates in personal area range 14 that typically extends up to 10 meters. More information about 15 Bluetooth can be found at <http://www.bluetooth.com/>. 16 17 Linux Bluetooth subsystem consist of several layers: 18 Bluetooth Core (HCI device and connection manager, scheduler) 19 HCI Device drivers (Interface to the hardware) 20 SCO Module (SCO audio links) 21 L2CAP Module (Logical Link Control and Adaptation Protocol) 22 RFCOMM Module (RFCOMM Protocol) 23 BNEP Module (Bluetooth Network Encapsulation Protocol) 24 CMTP Module (CAPI Message Transport Protocol) 25 HIDP Module (Human Interface Device Protocol) 26 SMP Module (Security Manager Protocol) 27 28 Say Y here to compile Bluetooth support into the kernel or say M to 29 compile it as module (bluetooth). 30 31 To use Linux Bluetooth subsystem, you will need several user-space 32 utilities like hciconfig and bluetoothd. These utilities and updates 33 to Bluetooth kernel modules are provided in the BlueZ packages. For 34 more information, see <http://www.bluez.org/>. 35 36if BT != n 37 38config BT_L2CAP 39 bool "L2CAP protocol support" 40 select CRC16 41 select CRYPTO 42 select CRYPTO_BLKCIPHER 43 select CRYPTO_AES 44 select CRYPTO_ECB 45 help 46 L2CAP (Logical Link Control and Adaptation Protocol) provides 47 connection oriented and connection-less data transport.
