How to interface lwBT stack for implementing Bluetooth PAN NAPprofile

[navin]

Hi,
I want to establish a Bluetooth Personal Area Network(PAN) between a
Mobile Data Terminal (MDT) running on Windows7 and PDAs running on
Windows mobile OSes.
As MDT needs to be act as a master device to transfer job requests to
PDAs, I want to implement Bluetooth PAN - NAP (Network Access Point)
profile in it, whereas for the PDAs to be acted as client devices
should be implemented on Bluetooth - PAN - PANU (PAN User)profile.

Since Microsoft Bluetooth Stack does not support PAN - NAP profile, I
planned to use open source lwBT (light weight Bluetooth) stack which
support PAN-NAP.

Also, can anybody help me on the steps/procedure to interface lwBT
based PAN-NAP profile implementation (in my MDT source code)

Also, I would like to know from where i can download the lwBT stack or
source code.

Thanks in advance,
Navin
