VBOX SPORT 20HZ

Is it possible to control an hardware Racelogic VBOX SPORT with the latest version of RaceChrono and an android HTC phone ?

I search the best precision possible and this antenna have a 20HZ frequency.

Thank for your answers and your help ;)

    Yes the latest version supports VBOX Sport. I have tested it with Samsung Galaxy S3 and Google Nexus S both are easily capable receiving 20 Hz. It should work with most other phones as well but I haven't had the opportunity to test. I recommend using external antenna with VBOX Sport for best results.
  • At what point does a Bluetooth serial connection become saturated and struggle to handle the data?

    With a VBOX Sport running at 20Hz as well as a bluetooth OBDII sending additional data and possibly even a RaceDAC sending additional non-OBDII data at up to 100Hz (I think that's what it supports). That sounds like quite a lot of data being transmitted around the car. Is there a danger that the bluetooth transport will not keep up or that the phone itself (or RaceChrono) wont be able to process all of the data.

    The VBOX Sport actually sends less data at 20 Hz than normal QSTARZ receiver at 5 Hz. This is because VBOX Sport uses proprietary binary protocol. Bluetooth 2 can send 3 Mbit/s where the once device like VBOX Sport will send in about 9600 bit/s and a OBD-II reader 2400 bit/s. So there is plenty of bandwidth to be eaten by radio interference etc. That said, some phones (not all) stubbornly limit data rate per device to 9600 bit/s which hurts data rate on devices like Garmin GLO and QSTARZ XT... But VBOX Sport is not affected as I think it's less than 9600 bit/s.
