The app will prompt you when a new firmware is available.
Alternatively, you can go into the “about” section of the app. If there is a new firmware available, it will give you the option to update the firmware.
Then follow the steps in the app to update the firmware.
Top tip: Do not uninstall the app at any point during the update. This will cause the update to fail and become stuck so you will not be able to reconnect.
If app freezes during the update please turn off your device then turn it back on rather than uninstalling the app.
