Bluetooth operates in personal area range 20 that typically extends up to 10 meters. More information about 21 Bluetooth can be found at <http://www.bluetooth.com/>. 22 23 Linux Bluetooth subsystem consist of several layers: 24 Bluetooth Core 25 HCI device and connection manager, scheduler 26 SCO audio links 27 L2CAP (Logical Link Control and Adaptation Protocol) 28 SMP (Security Manager Protocol) on LE (Low Energy) links 29 HCI Device drivers (Interface to the hardware) 30 RFCOMM Module (RFCOMM Protocol) 31 BNEP Module (Bluetooth Network Encapsulation Protocol) 32 CMTP Module (CAPI Message Transport Protocol) 33 HIDP Module (Human Interface Device Protocol) 34 35 Say Y here to compile Bluetooth support into the kernel or say M to 36 compile it as module (bluetooth). 37 38 To use Linux Bluetooth subsystem, you will need several user-space 39 utilities like hciconfig and bluetoothd. These utilities and updates 40 to Bluetooth kernel modules are provided in the BlueZ packages.

When the Bluetooth 91 subsystem is compiled into the kernel image, then the test cases 92 are run late in the initcall hierarchy. 93 94config BT_SELFTEST_ECDH 95 bool "ECDH test cases" 96 depends on BT_LE && BT_SELFTEST 97 help 98 Run test cases for ECDH cryptographic functionality used by the 99 Bluetooth Low Energy Secure Connections feature. 100 101config BT_SELFTEST_SMP 102 bool "SMP test cases" 103 depends on BT_LE && BT_SELFTEST 104 help 105 Run test cases for SMP cryptographic functionality, including both 106 legacy SMP as well as the Secure Connections features. 107 108config BT_DEBUGFS 109 bool "Export Bluetooth internals in debugfs" 110 depends on BT && DEBUG_FS 111 default y 112 help 113 Provide extensive information about internal Bluetooth states 114 in debugfs. 115 116source "drivers/bluetooth/Kconfig" 117
