Regarding low power, there is already the HCI interface which allows you to
cast HCI commands which would eventually configure your device in low power
mode. Its a feature, but should not take more than 1 day with the current
code. For this particular I recommend you to read the HCI commands and
Events.
- In the ideas page it is listed, lists this as 2.X specification

AFAIR in the software layers point of view there were not important changes
from 1.2 until 4.0. Most of them were focused in the physical layers.
As first I would better take an overview at the bluetooth architecture and
check in which layers Haiku is located. As obviously Haiku is not dealing
with hoping frequency nor any RF stuff.

Well that's because I am more or less alone in the development, and give the
updates via blog[7].
I would like to know :

The student's attitude is a part of a GSoC project. So your skills, willing
and community integration is what can make your project worth to be
eligible. Short answer, yes.

Currently on the Kernel area there is the L2CAP[1](still needs work) and
HCI[5] implementations and there is the HCI transport protocol H2[2]
(hardware support for usb dongles).
In the userland area we have the bluetooth_server[3] which interfaces with
the kernel. Then there is a kit[4] which provides an API for applications
development.
Currently the best example of an application using this API would be the
bluetooth preferences[6].
> (c) and How should I proceed ? any specific issue I should worry about ?
I would recommend to retrieve the code compile and test the stack. Perform a
scan(inquiry) with the preflet and finding something would mean it is
working.
Once you are done with this you can try one of the small tasks defined here:
