Having trouble connecting your SIT wearable? This guide covers the most common Bluetooth and device connection issues and how to resolve them.
Device Not Appearing in the Scan List
If the app cannot find your device, work through the following checks:
Open your phone's Settings and confirm Bluetooth is turned on.
The SIT app needs Bluetooth and Location permissions on both iOS and Android. Go to Settings > Apps > SIT and make sure both are set to Allow.
Press and hold the button on the wearable. The LED should flash, indicating it is advertising and ready to connect.
Stay within 2–3 metres during scanning. Walls and metal objects can reduce signal strength.
Check for other connections
A SIT device can only connect to one phone at a time. If a teammate has already connected to the device, it will not appear in your scan list. Ask them to disconnect first.
Weak Signal or Interference
If the device appears but the signal is weak (few bars), try these steps:
Move your phone closer to the wearable for a stronger signal.
Move away from Wi-Fi routers, microwaves, and other Bluetooth devices that can compete for the 2.4 GHz band.
Metal surfaces and concrete walls weaken BLE signals. Try to maintain a clear line of sight.
Device Disconnects Mid-Session
Your data is safe
If a device disconnects during a session, data recorded up to that point is preserved on the app. You will not lose any impacts already captured.
The most common cause of disconnects is distance. Move your phone closer to the player wearing the device.
The app will show a Reconnect option on the player card. Tap it to re-establish the connection without ending the session.
A critically low battery can cause unexpected disconnects. Charge the device if possible.
Device Shows in List but Won't Connect
If you can see the device but tapping Connect fails or hangs, try:
Turn the wearable off, wait 5 seconds, and turn it back on. This clears any stale connection state on the device.
Force-close the app and reopen it, then try connecting again.
Toggle Bluetooth off and on in your phone settings, then reopen the app and scan again.
As a last resort, a full phone restart clears the OS Bluetooth stack and resolves most persistent issues.
