Are you sure u can do this, without breaking the GPL?
Can't be too tightly integrated, that is for sure.

Hi ,
do you mean to say that
'porting bluez protocol stack ' into VxWorks violates GPL.

Actually i have not thought of the GPL here.

Could you please tell me in detail.
It would of great helpto me.

Tonnes of thanks in advance,
karthik bala guru.

It doesnt violate GPL, you just have to put the VxWorks source code into GPL
which probably violates the agreement with Wind River.

Try this: <http://www.gnu.org/copyleft/gpl.html>.

It was the first hit from about 25 million when
Googling for 'GPL'. Please learn to use Google.

Tuano,
fine and thanku.
i know about copyleft .... gpl.
But, i would like to have any doc/link that was stated earlier .(
particularly w.r.t porting bluetooth stack (arm-linux) into that of
vxworks !! )

thanx and regards,

That is just a logical conclusion of the GPL agreement
and no documentation exists AFAIK.

If you use the arm-linux code and link with VxWorks
then you cannot provide the resulting product
to anyone without releasing the source of everything.
This then includes VxWorks.

There are some limitations.
You can sell a PC with Windows and a Windows GNU compiler
without having to priovide the source of Windows,
but I do not think you can link Vxworks with a BT stack.

If you can have a dynamically linked library with the BT stack,
then you might get away with it.

Did you read the GNU documentation?

You cannot copy the GPL'd protocol stack to
a closed-source system, unless you can get
the VxWorks sources published under GPL.

It is no too probable that anybody wants to
help you to break the licensing limitations.

It seems that the only way out is that you
write a new protocol stack from scratch
(not copying *any* of the Linux one).

Yes Tauno,
I do know and understand that GPL'd protocol stack cannot be taken into
Closed-Source System.
Anyhow, if i just copy the GPL'd protocol stack(in linux) into vxworks.
How would it work ? it is not possible in that way. So I am not
Breaking GPL !!!!
Hence, I too think and beleive that i have to write the protocol stack
in Vxworks from the scratch with the bluetooth protocol specifications
and with my previous bluetooth experience !!

Thanks and regards,

Thanx for that Samuelsson,
I do think of implementing an idea of having a THING similar to
dynamically linked library with the BT stack for aavoiding the GPL
agreement problem.
In that way i can get away with it.
Anyhow, i am still looking for other ways also.
Do let me know, if u have any.
