How syncing works

The sensor records everything on its own. Your phone stays on the beach, and the session moves across afterwards.

The sequence

1. Back on land, give the sensor's button a short press. The light changes from blinking red to pulsing blue: the recording has stopped, the session is stored in the sensor's own memory, and the sensor is in sync mode.
2. Open the app with the sensor nearby, tap SYNC and pick your sport.
3. The app finds the sensor over Bluetooth and the light turns solid blue. Your phone then joins the sensor's own Wi-Fi network to copy the session, and the light turns white while it transfers. If your phone says that network has "No Internet", that is normal: stay connected.
4. The app processes the session and it appears in your feed with route, speed, distance and sport metrics.

How long it takes

Usually seconds, sometimes a couple of minutes. A long session carries more data, so give it time. Keep the app in the foreground and the sensor within a metre or two while the transfer runs.

Very short recordings are not kept

Recordings shorter than about five minutes are not kept on the sensor, so a quick test on the beach will not show up in the app. Ride for at least five minutes.

Nothing is lost if you wait

Sessions stay on the sensor until they have transferred successfully. You can ride all weekend, sync on Sunday evening, and everything comes across. There is no need to sync between sessions.
