If you’re wondering why your data is not completely recorded or you’re not seeing the lap times, here’s the things you should try to check first. If you cannot resolve the issue, please contact the support, and be prepared sharing your troubled session with us.
- Check for bad GPS signal
Open your session and tap the round “Route” button to open analysis of your session, and make sure the graph and map are visible. Then scroll the graph to left, while looking at the map. Do the trajectories on the map go on the track or near it within maybe 20 meters? If the trajectories are all over the place, and they do not resemble the real traveled path, then you have bad GPS signal.
Solution: The GPS receiver must be kept in clear view to the sky. If you’re using the built-in GPS on your phone; the phone must be kept in a phone holder with clear view to the sky – it will not work from your pocket! When using the built-in GPS, the best places for the phone are on dashboard near the windshield of your car, or near the instrument cluster on your motorcycle. If you’re using an external GPS, the best place for it is on the tail section of your motorcycle furthest away from the rider. On a car it’s usually the lower part of the windshield. An external Bluetooth GPS is needed if you want to keep the phone in your pocket or in the glove compartment. An external GPS is always recommended for anything beyond casual use of the app. - Check for Start/Finish line placement
Open the analysis same as above, and while scrolling the graph look for the crossing of the Start/Finish line. It is a red line with and arrow. The trajectory on the map should pass through the Start/Finish line, to the direction of the red arrow. If the direction is wrong, or the trajectory goes past the trap, your laps will not register.
Solution: You can either create a completely new track with correct traps, or make a copy of the current track and edit the traps that are incorrectly placed. - Check your phone settings
It’s possible that RaceChrono is unable to record your data when the app is put to background or the screen is locked.
Solution: On iPhone, make sure Settings > RaceChrono Pro > Location is set to Always. On Android phone, you should configure RaceChrono to run in “unrestricted” power mode.
