2 # Bluetooth subsystem configuration
6 tristate "Bluetooth subsystem support"
7 depends on NET && !S390
8 depends on RFKILL || !RFKILL
11 select CRYPTO_BLKCIPHER
17 Bluetooth is low-cost, low-power, short-range wireless technology.
18 It was designed as a replacement for cables and other short-range
19 technologies like IrDA. 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/>.
23 Linux Bluetooth subsystem consist of several layers:
25 HCI device and connection manager, scheduler
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)
35 Say Y here to compile Bluetooth support into the kernel or say M to
36 compile it as module (bluetooth).
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. For
41 more information, see <http://www.bluez.org/>.
44 bool "Bluetooth Classic (BR/EDR) features"
48 source "net/bluetooth/rfcomm/Kconfig"
50 source "net/bluetooth/bnep/Kconfig"
52 source "net/bluetooth/cmtp/Kconfig"
54 source "net/bluetooth/hidp/Kconfig"
57 bool "Bluetooth High Speed (HS) features"
62 bool "Bluetooth Low Energy (LE) features"
67 tristate "Bluetooth 6LoWPAN support"
68 depends on BT_LE && 6LOWPAN
70 IPv6 compression over Bluetooth Low Energy.
73 bool "Bluetooth self testing support"
74 depends on BT && DEBUG_KERNEL
76 Run self tests when initializing the Bluetooth subsystem. This
77 is a developer option and can cause significant delay when booting
80 When the Bluetooth subsystem is built as module, then the test
81 cases are run first thing at module load time. When the Bluetooth
82 subsystem is compiled into the kernel image, then the test cases
83 are run late in the initcall hierarchy.
85 config BT_SELFTEST_ECDH
86 bool "ECDH test cases"
87 depends on BT_LE && BT_SELFTEST
89 Run test cases for ECDH cryptographic functionality used by the
90 Bluetooth Low Energy Secure Connections feature.
92 config BT_SELFTEST_SMP
94 depends on BT_LE && BT_SELFTEST
96 Run test cases for SMP cryptographic functionality, including both
97 legacy SMP as well as the Secure Connections features.
100 bool "Export Bluetooth internals in debugfs"
101 depends on BT && DEBUG_FS
104 Provide extensive information about internal Bluetooth states
