    Remote access to OBDKey WiFi

    Hi Gary
    the way it would work is that i would assign you an ip address and a port number then you can access remotely using that. You wouldn't need any OS specifics from my side.

    PLX KiWi WiFi initialization issue

    3.) Start your ELM327 command cycle (i.e. warm reset, pull protocol, supported PIDs).

    Hi Mike! I wrote you to you fuzzyluke support mail, I don't know if you received. BTW I write here, maybe someone else could help.

    Following your procedure everything works great: I connect to the device opening a TCP Socket (LINK led stop blinking and becomes fix), requesting and reading PID data. I tried this though iphone and using telnet through terminal on a macBook connected to the PLX (in this case no socket manual creation is needed).

    The only problem is that, if I don't send command for about 10 seconds, connection is closed: "connection lost by foreign host" and LINK led starts blinking again. I have to reboot the initialization process in order to play again with ECU.

    Here my initialization process:

    1) open TCP socket to 192.168.0.10:35000 and save input and output stream objects (OR SIMPLY: telnet 192.168.0.10:35000)
    2) start writing to output object:
    +<CR>
    ATZ<CR>
    ATE0<CR>
    OBD commands: example: 01 0C (RPM) and answer is right 41 01 XX XX.

    If no commands, connection is closed as said.
    I also tried to set the protocol with ATSP0 (auto) and ATSP3, ATSP4, ATSP5 and after that I set the wakeup time: ATSWFF (5 seconds), without success.

    Someone can help?
    Thank you very much.

    Hey guys,

    I'm interested in this stuff too.

    I was amazed to find a bluetooth obd dongle out there for $16,
    does this do what you want?

    why would someone choose wifi over bluetooth? (honest question)

    i thought it might be a price thing but they seem to be the same price....except that wifi is point-to-point so your sacrificing your internet connectivity.

    I already have a bluetooth OBDKey [albeit one of the older ones, with a really low samplerate]; I was looking for a wifi one because communicating with it requires actual different code to be written [unlike the bluetooth ones, which are just serial by the time they get to userland.]

    Bluetooth != Wifi, but thanks for playing


    To be honest, I prefer bluetooth myself, so I am interested in hearing the answer to justchat_1's question as well.

    For a long time, the iphone had a hopelessly crippled bluetooth stack, so wifi was the only way to communicate wirelessly with it. I believe that that's the heritage of wifi dongles [I remember seeing devtoaster first using it and thinking that was pretty cool].

    Isn't it still the case that you can't use the iPhone to communicate w/ non-Apple-approved Bluetooth dongles?

    Currently the cost of Bluetooth modules is about half the cost of WiFi.
