If there is an update to the firmware on your Atom you will be prompted via your Wattbike Hub App to update the software.
Once you open the Wattbike Hub App to complete a session you will receive a prompt asking you to download the latest firmware. Select 'Yes' and this will automatically update.
Should you have an iOS device (Apple) and click 'No', it will require you to delete the application and reinstall. Your device will then be prompted to update the firmware again. From here you will need to select 'Yes'.
Please ensure you have a good Wifi connection and do not close down the App whilst the update is being completed.
