 | 	  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) | 
 | 	     SMP Module (Security Manager 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 bluetoothd.  These utilities and updates | 
 | 	  to Bluetooth kernel modules are provided in the BlueZ packages.  For | 
 | 	  more information, see <http://www.bluez.org/>. |

 | 	  connection oriented and connection-less data transport.  L2CAP | 
 | 	  support is required for most Bluetooth applications. | 
 |  | 
 | 	  Also included is support for SMP (Security Manager Protocol) which | 
 | 	  is the security layer on top of LE (Low Energy) links. |

 | 	  SCO link provides voice transport over Bluetooth.  SCO support is | 
 | 	  required for voice applications like Headset and Audio. |
