    How to connect 2 cars (both with CarPC) to have audio, file transfer?

    I would like to know if there exist a software to connect 2 different cars (both CarPC with USB bluetooth dongle or WLAN USB dongle) to make audio conversation or file transfer?

    Recently I tried this with WLAN but would like to know if it is possible via bluetooth too. And of course I haven't found a software to have audio conversations... something like lite version of Messenger that should not connect to a main server, only between 2 clients?

    WLAN .. well it's easy, it's like connecting two PC's in lan (in fact they are nothing less/more than two normal PC's). For audio conversation, try TeamSpeak, you can install a server (light) on one of the two cars.

    as ARCTiC says set up the WLAN as AD-HOC clients, and depending on the wifi cards and location of the cards in your car you should be able to get enouch distance to use TeamSpeak while driving together, you could then use windows file sharing to share your files [hint: dont do this while driving] ... as for blue tooth, i would suggest using this for only small files in a pinch, the bandwidth of bluetooth is much smaller than 802.11B/G and the range is MUCH smaller, but by all means if you're parked next to each other in a parking lot and want to transfer via bluetooth go for it (or it is good to get stuff off of other blue tooth devices [PDA's] ...

    one last thought, set up your AD-HOC network (WLAN) between the computers, install TeamSpeak, then use a BlueTooth head set to talk to the other car over TeamSpeak ... that sounds like a nice FREE set up assuming you get to drive near people w/ the same set up

    one last FINAL thought, and if no ones around to talk to, switch your WiFi card back to infrastructure mode (instead of AD-HOC) find a wireless hotspot, hop on skype and make free calls (to ALL US phone numbers) till the end of this year ...

    GOOD LUCK

    Thanks for quick info! I case I use wireless ad-hoc mode, is there any possiblity to switch mode from ad-hoc to infrastructure faster than usual way? And if I remember in case I want to set up ad-hoc mode, you have to enter manually ip on every client? And everytime when you want to switch to structura again I have to delete those numbers? Is there a faster way?

    I am downloading it right now. What in case if we are 3 of us. Only one have server... what in case if the other 2 meet each other... none of them is server. Can every CarPC be server and client at the same time and only switch what he would like to be?

    I would love it so much if "we" car-pc community would kick the automotive industry with our own car2car communication (protocol) standard based on WLAN.

    http://www.car-to-car.org/

    Instead of the closed bull**** from the industry - an open standard for all our frontends and not 2010 ! With public accessable documentation - rapidly evolving with the speed of the IT industry !

    A blame for multimillion dollar enterprises !

    I'd look into the possibility of using a "profile" in your wireless software or maybe even the windows wireless utilities for the IP switching issues [i know of a few simple ways to do this in linux, too bad that doesnt help at all here]

    i think you're talking about ifconfig, there is something like it in windows, but it's not as good as ifconfig (hey it's windows, you should be used to the dissapointments by now)

    in windows you can use netsh.exe, it allows you to create scripts with your tcp/ip configurations, you would just have to write the script and create a shortcut inside RR in the launch section

    this might help you out

    Real dead stupid way would be stop by your local Sam's club and pick up a linksys wrt. Make a network called "get your tunes here", no encryption. You can run the thing off a 12v cig adapter or even a few AA's.
    Failure is not an option....
