I'm a little lost in other implementation point: If we have the A peer and B peer connected trough tcp, Imagine that the A phone wants to connect B one, then it inquires and finds the hci device of the A PC and sends the connection requests and all other stuff, these data is sniffed with the A raw socket and forwarded to the B PC by TCP where is sent over B's hci device again, but... hci frames from A phone may be sent to the A PC's hci device's bluetooth address, not to B phone's Bluetooth address, may this be a problem? Would I need to parse the frames to change the destination address or change the A hci device address to B phone's address and B one to A phone address? Can I change the local chip BT address? I'll try to get more familiar with this low-level Bluetooth stuff. Thank you for spending your time helping me. -----Mensaje original----- De: bluez-devel-admin@lists.sourceforge.net [mailto:bluez-devel-admin@lists.sourceforge.net] En nombre de Marcel Holtmann Enviado el: domingo, 02 de enero de 2005 20:21 Para: BlueZ Mailing List Asunto: RE: [Bluez-devel] HCI forwarding Hi, > Device detection is not a problem since bluez does it for me (I only have to > set the local class of device to the correct value (0x500204) in order to > deceiving mobile phones in both sides).

However the ACL MTU should match. The role switches might be a little tricky. Forwarding the HCI commands and events is not that easy. You must keep an eye on the flow control mechanism of HCI, but this is all still doable and there are more ways for doing it. > Is this possible in this way?, In other?, Am I wrong? > (I wrote the app sniffing and forwarding hci frames (it seems that "works") > but I had no chance for testing it). It is possible and the best way depends on what you wanna do. Basically I used L2CAP and RFCOMM forwarding a lot of this to crack protocol stuff that was going on between some devices. Best example is the Nokia PhoNet protocol.
