Micrsoft defined a set for HCI vendor extensions. Check the following link for details: https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/microsoft-defined-bluetooth-hci-commands-and-events This provides the basic framework to enable the extension and read its supported features. Drivers still have to declare support for this extension before it can be utilized by the host stack.

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
|
|
SCO audio links
|
|
L2CAP (Logical Link Control and Adaptation Protocol)
|
|
SMP (Security Manager Protocol) on LE (Low Energy) links
|
|
HCI Device drivers (Interface to the hardware)
|
|
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 bluetoothd. These utilities and updates
|
|
to Bluetooth kernel modules are provided in the BlueZ packages. For
|
|
more information, see <http://www.bluez.org/>.

Run self tests when initializing the Bluetooth subsystem. This

is a developer option and can cause significant delay when booting

the system.

When the Bluetooth subsystem is built as module, then the test

cases are run first thing at module load time. When the Bluetooth

subsystem is compiled into the kernel image, then the test cases

are run late in the initcall hierarchy.
