2 # Bluetooth subsystem configuration
6 tristate "Bluetooth subsystem support"
7 depends on NET && !S390
8 depends on RFKILL || !RFKILL
11 select CRYPTO_BLKCIPHER
18 Bluetooth is low-cost, low-power, short-range wireless technology.
19 It was designed as a replacement for cables and other short-range
20 technologies like IrDA. 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/>.
24 Linux Bluetooth subsystem consist of several layers:
26 HCI device and connection manager, scheduler
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)
36 Say Y here to compile Bluetooth support into the kernel or say M to
37 compile it as module (bluetooth).
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. For
42 more information, see <http://www.bluez.org/>.
45 bool "Bluetooth Classic (BR/EDR) features"
49 Bluetooth Classic includes support for Basic Rate (BR)
50 available with Bluetooth version 1.0b or later and support
51 for Enhanced Data Rate (EDR) available with Bluetooth
54 source "net/bluetooth/rfcomm/Kconfig"
56 source "net/bluetooth/bnep/Kconfig"
58 source "net/bluetooth/cmtp/Kconfig"
60 source "net/bluetooth/hidp/Kconfig"
63 bool "Bluetooth High Speed (HS) features"
67 Bluetooth High Speed includes support for off-loading
68 Bluetooth connections via 802.11 (wifi) physical layer
69 available with Bluetooth version 3.0 or later.
72 bool "Bluetooth Low Energy (LE) features"
76 Bluetooth Low Energy includes support low-energy physical
77 layer available with Bluetooth version 4.0 or later.
80 tristate "Bluetooth 6LoWPAN support"
81 depends on BT_LE && 6LOWPAN
83 IPv6 compression over Bluetooth Low Energy.
86 bool "Enable LED triggers"
91 This option selects a few LED triggers for different
95 bool "Bluetooth self testing support"
96 depends on BT && DEBUG_KERNEL
98 Run self tests when initializing the Bluetooth subsystem. This
99 is a developer option and can cause significant delay when booting
102 When the Bluetooth subsystem is built as module, then the test
103 cases are run first thing at module load time. When the Bluetooth
104 subsystem is compiled into the kernel image, then the test cases
105 are run late in the initcall hierarchy.
107 config BT_SELFTEST_ECDH
108 bool "ECDH test cases"
109 depends on BT_LE && BT_SELFTEST
111 Run test cases for ECDH cryptographic functionality used by the
112 Bluetooth Low Energy Secure Connections feature.
114 config BT_SELFTEST_SMP
115 bool "SMP test cases"
116 depends on BT_LE && BT_SELFTEST
118 Run test cases for SMP cryptographic functionality, including both
119 legacy SMP as well as the Secure Connections features.
122 bool "Export Bluetooth internals in debugfs"
123 depends on BT && DEBUG_FS
126 Provide extensive information about internal Bluetooth states
