Bluetooth operates in personal area range 21 that typically extends up to 10 meters. More information about 22 Bluetooth can be found at <http://www.bluetooth.com/>. 23 24 Linux Bluetooth subsystem consist of several layers: 25 Bluetooth Core 26 HCI device and connection manager, scheduler 27 SCO audio links 28 L2CAP (Logical Link Control and Adaptation Protocol) 29 SMP (Security Manager Protocol) on LE (Low Energy) links 30 HCI Device drivers (Interface to the hardware) 31 RFCOMM Module (RFCOMM Protocol) 32 BNEP Module (Bluetooth Network Encapsulation Protocol) 33 CMTP Module (CAPI Message Transport Protocol) 34 HIDP Module (Human Interface Device Protocol) 35 36 Say Y here to compile Bluetooth support into the kernel or say M to 37 compile it as module (bluetooth). 38 39 To use Linux Bluetooth subsystem, you will need several user-space 40 utilities like hciconfig and bluetoothd. These utilities and updates 41 to Bluetooth kernel modules are provided in the BlueZ packages.

When the Bluetooth 92 subsystem is compiled into the kernel image, then the test cases 93 are run late in the initcall hierarchy. 94 95config BT_SELFTEST_ECDH 96 bool "ECDH test cases" 97 depends on BT_LE && BT_SELFTEST 98 help 99 Run test cases for ECDH cryptographic functionality used by the 100 Bluetooth Low Energy Secure Connections feature. 101 102config BT_SELFTEST_SMP 103 bool "SMP test cases" 104 depends on BT_LE && BT_SELFTEST 105 help 106 Run test cases for SMP cryptographic functionality, including both 107 legacy SMP as well as the Secure Connections features. 108 109config BT_DEBUGFS 110 bool "Export Bluetooth internals in debugfs" 111 depends on BT && DEBUG_FS 112 default y 113 help 114 Provide extensive information about internal Bluetooth states 115 in debugfs. 116 117source "drivers/bluetooth/Kconfig" 118
