2 # Bluetooth subsystem configuration
6 tristate "Bluetooth subsystem support"
7 depends on NET && !S390
8 depends on RFKILL || !RFKILL
10 Bluetooth is low-cost, low-power, short-range wireless technology.
11 It was designed as a replacement for cables and other short-range
12 technologies like IrDA. Bluetooth operates in personal area range
13 that typically extends up to 10 meters. More information about
14 Bluetooth can be found at <http://www.bluetooth.com/>.
16 Linux Bluetooth subsystem consist of several layers:
17 Bluetooth Core (HCI device and connection manager, scheduler)
18 HCI Device drivers (Interface to the hardware)
19 SCO Module (SCO audio links)
20 L2CAP Module (Logical Link Control and Adaptation Protocol)
21 RFCOMM Module (RFCOMM Protocol)
22 BNEP Module (Bluetooth Network Encapsulation Protocol)
23 CMTP Module (CAPI Message Transport Protocol)
24 HIDP Module (Human Interface Device Protocol)
26 Say Y here to compile Bluetooth support into the kernel or say M to
27 compile it as module (bluetooth).
29 To use Linux Bluetooth subsystem, you will need several user-space
30 utilities like hciconfig and hcid. These utilities and updates to
31 Bluetooth kernel modules are provided in the BlueZ packages.
32 For more information, see <http://www.bluez.org/>.
35 tristate "L2CAP protocol support"
39 L2CAP (Logical Link Control and Adaptation Protocol) provides
40 connection oriented and connection-less data transport. L2CAP
41 support is required for most Bluetooth applications.
43 Say Y here to compile L2CAP support into the kernel or say M to
44 compile it as module (l2cap).
46 config BT_L2CAP_EXT_FEATURES
47 bool "L2CAP Extended Features support (EXPERIMENTAL)"
48 depends on BT_L2CAP && EXPERIMENTAL
50 This option enables the L2CAP Extended Features support. These
51 new features include the Enhanced Retransmission and Streaming
52 Modes, the Frame Check Sequence (FCS), and Segmentation and
53 Reassembly (SAR) for L2CAP packets. They are a required for the
54 new Alternate MAC/PHY and the Bluetooth Medical Profile.
56 You should say N unless you know what you are doing. Note that
57 this is in an experimental state yet.
60 tristate "SCO links support"
63 SCO link provides voice transport over Bluetooth. SCO support is
64 required for voice applications like Headset and Audio.
66 Say Y here to compile SCO support into the kernel or say M to
67 compile it as module (sco).
