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.

This 72 is a developer option and can cause significant delay when booting 73 the system. 74 75 When the Bluetooth subsystem is built as module, then the test 76 cases are run first thing at module load time. When the Bluetooth 77 subsystem is compiled into the kernel image, then the test cases 78 are run late in the initcall hierarchy. 79 80config BT_SELFTEST_ECDH 81 bool "ECDH test cases" 82 depends on BT_LE && BT_SELFTEST 83 help 84 Run test cases for ECDH cryptographic functionality used by the 85 Bluetooth Low Energy Secure Connections feature. 86 87config BT_SELFTEST_SMP 88 bool "SMP test cases" 89 depends on BT_LE && BT_SELFTEST 90 help 91 Run test cases for SMP cryptographic functionality, including both 92 legacy SMP as well as the Secure Connections features. 93 94config BT_DEBUGFS 95 bool "Export Bluetooth internals in debugfs" 96 depends on BT && DEBUG_FS 97 default y 98 help 99 Provide extensive information about internal Bluetooth states 100 in debugfs. 101 102source "drivers/bluetooth/Kconfig" 103
