Identify phone model by bluetooth

Hi everybody,

I hope this is the right newsgroup for my question.


I would like to know if it's possible to know the manufacturer/model of
a phone via bluetooth, using bluetooth service discovery or some other
method.

Calling service discovery I can just find if the mobile phone support
OBEX or other functions: I can guess to have found a nokia phone if
there is a service called "Nokia data suite", or that the mobile phone
is a symbian one just because there is a Symbian service exposed.

Somewhere I've read about some phone specific files I can request using
obex file exchange than contains these infos. Is this true? Where can I
find info about it?

Many thanks for any help.

Regards

JB
