Hi Marcel,=20
Why not use PAN profile instead of RFCOMM. We create an IP =
infrastructure (using Ethernet Bridging) route (or broadcast) packets =
between devices. If some BTH devices donot support PAN profile we can =
make devices attached to them as proxies. The adv of using PAN profile =
is that it can easily attached to IP back bone and this proj requires =
that (although it can result in some addressing issues). I am not sure =
if this is what David wants but you are correct there is no need to =
spoof addresses or try getting the raw BTH packets etc.
regards
Somil

I made a quick look through your documents. Spoofing of a BD_ADDR's is
not what you really want and of course it is also not possible. You
should think more of service forwarding. This means tunneling of the
complete L2CAP layer or dedicated SDP service records/RFCOMM channel
tunneling.

I haven't read his documents in detail, but as I understand it he want's
to connect from a PC in one piconet to a mobile phone in another
piconet. These piconets are connected through an IP backbone and not via
a scatternet. So he must make the SPD records of the phone visible in
both piconets and if needed route a L2CAP or RFCOMM connection between
them. However it is his master thesis and not mine.

Marcel
