My RaceBox won't connect

Checklist

1. Is it on and charged? The status LED should be lit. A flat RaceBox advertises nothing.
2. Is it nearby? Keep it within a few meters while pairing.
3. Is Bluetooth on — and allowed? Check the phone's Bluetooth is on, and that LapperSnapper has Bluetooth permission — on iPhone, Settings → LapperSnapper → Bluetooth; on Android, Settings → Apps → LapperSnapper → Permissions (listed as Nearby devices on Android 12 and later).
4. Is another app holding it? A RaceBox accepts one connection at a time. Fully close the RaceBox app or any other telemetry app, then scan again.
5. Rescan. Record → RaceBox → Scan for RaceBox, then tap your RaceBox in the list. If the app says No RaceBox found, power-cycle the RaceBox and toggle the phone's Bluetooth.

Connects, then drops

• Keep the phone and RaceBox on the same side of the kart if you can; carbon and bodywork attenuate Bluetooth.
• Phone battery-saver modes throttle Bluetooth in the background — disable them for a race day.

Can't start recording?

If the app is busy downloading the RaceBox's stored history, recording waits until that finishes — give it a moment, then start again.

RaceBox needs the iPhone or Android app — the web app can't use Bluetooth.

Still stuck? Contact support with your RaceBox model and phone model.
