Description
Bluetooth is low-cost, low-power, short-range wireless technology. It
was designed as a replacement for cables and other short-range
technologies such as IrDA. Bluetooth operates in personal area range that
typically extends up to 10 meters. More information about Bluetooth

The 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
To use the Linux Bluetooth subsystem, you will need several user-space
utilities such as
hciconfig
and
hcid
. These utilities and updates to
Bluetooth kernel modules are provided in the BlueZ packages at
