Two piconets = (basically piconet devices) can be connected via an ethernet wire or = WLAN AP. I have done that its not magic. After connecting we can create = an IP infrastructure make every device IP addressable (that is where I = said there can be some IP addressing problem and I am trying to solve & = publish it anyway its no concern here). Now the question comes sending = SDP records - to know what kind of service each piconet device provides = etc ?? If we have an IP infrastructure then why nt use UPnP protocol we = don't need BTH SDP protocol (I guess UPnP protocol provides more = flexibility than SDP (I am nt an expert in UPnP)). But if you still want = BTH SDP then send SDP records in IP packets (not good). (Make IP = connections between devices to transfer data etc no need to make RFCOMM = connections run thousands of legacy IP applications without modifying a = single line of code, I am nt able to understand why people are pushing = for RFCOMM etc but nt what we are discussing here).=20 regards Somil -----Original Message----- From: bluez-users-admin@lists.sourceforge.net [mailto:bluez-users-admin@lists.sourceforge.net]On Behalf Of ext Marcel Holtmann Sent: Sunday, June 06, 2004 7:56 PM To: Asthana Somil (EXT-Nokia-NRC/Boston) Cc: d.mackie@ru.ac.za; BlueZ Mailing List Subject: RE: [Bluez-users] Can you spoof/forge Bluetooth Devices/Address? Hi Somil, > 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. 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.
