Compatibility of Harry's Laptimer with Racebox Mini's Accelerometer

I am currently using Harry's Laptimer Grand Prix and I'm interested in understanding if it's possible to utilize the accelerometer integrated into the Racebox Mini rather than relying on the phone's accelerometer.

While the phone's accelerometer can be temporarily fixed and removed, I believe that the Racebox Mini (fixed tightly on car) may offer a more stable and reliable measurement. I'm keen to explore this option for enhanced accuracy and stability during my usage.

Could you kindly provide guidance or information on how I might leverage the Racebox Mini's accelerometer within current version of the Harry's Laptimer Grand Prix?

Racebox's accelerometer is not supported. Transferring this data on top of GPS would be too much for BT LE bandwidth. The only benefit would be the named fixed install position making LapTimer acceleration rotation obsolete. Smartphone IMU sensors are pretty precise and update rates are high.

I’ve used Harry’s Laptimer for a while, and as far as I know, it doesn’t support external accelerometers like the one in the Racebox Mini—it sticks to the phone’s sensors. I had similar concerns about accuracy, so I focused on securing my phone as tightly as possible, which helped a bit. Pairing it with an external GPS was a game changer for me, though—it improved the overall reliability of the data. It’s worth reaching out to the developers to suggest support for the Racebox Mini; they’re usually pretty open to ideas from users.
