RaceBox MINI

Hi all,
i'm Alessio from Italy and i'm a fairly new user of RaceChrono.

As the title suggests, i would like to ask if the complete device support to the app is confirmed and if anyone had already the opportunity to test that.

Thank you in advance

    It's official. Current versions of RaceChrono do support RaceBox Mini. See the announcement here: https://racechrono.com/article/3004
  • I will retrive data via bluetooth from both an ELM327 (rpm, speed, throttle position) and the racebox mini (gps, gyro, accelerometer), is it possible or the app can only have one BT communication at a time?
  • I've been using OBDLink MX+ over Bluetooth (I believe?) and XGPS160 at the same time, no problem.

    @MadeinAlesio It works great with other Bluetooth devices. Just like any other Bluetooth device :)
  • Thank you very much for the information, now we just have to wait for it to be delivered! :smiley:
  • I just used Racechrono v7.5.2 and racebox mini. they paired nicely and logged data on demand. however, i am seeing a lot of "noise" in the lateral g data. any thoughts?

    It's normal to see noise in there. RaceChrono will have better IMU functionality soon, and will smooth out these values.

    That said, I'm haven't yet been able to confirm if the IMU data from the RaceBox Mini is any good for further processing, but we'll see that soon.
  • I've just got my mini. Does RaceChrono use the mini's g sensor? or only the 25Hz GPS. Thanks

    @hasole RaceChrono uses the GPS only at the moment. Future versions of RC will have functionality that uses the IMU, at least on the phone, maybe also the RaceBox's.
  • Just got my mini too. Works well with RC at 25Hz. Thanks for the rapid support!

  • @aol Thank you for confirming that. I noticed that the Mini shows the accel and gyro at 25hz but my phone data rate is 50hz.
