Calibration does not start or freezes

Before troubleshooting, check the following:

• Your smartphone is connected to Wi-Fi.
• Bluetooth is enabled.
• You are using the latest version of the Matchflight App.
• Your phone's operating system is up to date.
• HEYLO is connected to power.

What you can do:

1. Unplug HEYLO from the power source.
2. Wait at least 10 seconds.
3. Reconnect the power.
4. Completely close the Matchflight App.
5. Reopen the app and try the calibration process again.

If calibration still does not start, restart your smartphone and repeat the setup process.
