 | 	help | 
 | 	  Bluetooth is low-cost, low-power, short-range wireless technology. | 
 | 	  It was designed as a replacement for cables and other short-range | 
 | 	  technologies like IrDA.  Bluetooth operates in personal area range | 
 | 	  that typically extends up to 10 meters.  More information about | 
 | 	  Bluetooth can be found at <http://www.bluetooth.com/>. | 
 |  | 
 | 	  Linux Bluetooth subsystem consist of several layers: | 
 | 	     Bluetooth Core (HCI device and connection manager, scheduler) | 
 | 	     HCI Device drivers (Interface to the hardware) | 
 | 	     SCO Module (SCO audio links) | 
 | 	     L2CAP Module (Logical Link Control and Adaptation Protocol) | 
 | 	     RFCOMM Module (RFCOMM Protocol)   | 
 | 	     BNEP Module (Bluetooth Network Encapsulation Protocol) | 
 | 	     CMTP Module (CAPI Message Transport Protocol) | 
 | 	     HIDP Module (Human Interface Device Protocol) | 
 |  | 
 | 	  Say Y here to compile Bluetooth support into the kernel or say M to | 
 | 	  compile it as module (bluetooth). | 
 |  | 
 | 	  To use Linux Bluetooth subsystem, you will need several user-space | 
 | 	  utilities like hciconfig and hcid.  These utilities and updates to | 
 | 	  Bluetooth kernel modules are provided in the BlueZ packages. | 
 | 	  For more information, see <http://www.bluez.org/>. |

 | 	depends on BT | 
 | 	select CRC16 | 
 | 	help | 
 | 	  L2CAP (Logical Link Control and Adaptation Protocol) provides | 
 | 	  connection oriented and connection-less data transport.  L2CAP | 
 | 	  support is required for most Bluetooth applications. | 
 |  | 
 | 	  Say Y here to compile L2CAP support into the kernel or say M to | 
 | 	  compile it as module (l2cap). | 
 |  | 
 | config BT_L2CAP_EXT_FEATURES | 
 | 	bool "L2CAP Extended Features support (EXPERIMENTAL)" | 
 | 	depends on BT_L2CAP && EXPERIMENTAL | 
 | 	help | 
 | 	  This option enables the L2CAP Extended Features support. These | 
 | 	  new features include the Enhanced Retransmission and Streaming | 
 | 	  Modes, the Frame Check Sequence (FCS), and Segmentation and | 
 | 	  Reassembly (SAR) for L2CAP packets. They are a required for the | 
 | 	  new Alternate MAC/PHY and the Bluetooth Medical Profile. | 
 |  | 
 | 	  You should say N unless you know what you are doing. Note that | 
 | 	  this is in an experimental state yet. | 
 |  | 
 | config BT_SCO | 
 | 	tristate "SCO links support" | 
 | 	depends on BT | 
 | 	help | 
 | 	  SCO link provides voice transport over Bluetooth.  SCO support is | 
 | 	  required for voice applications like Headset and Audio. | 
 |  | 
 | 	  Say Y here to compile SCO support into the kernel or say M to | 
 | 	  compile it as module (sco). |
