Firmware Update

From time to time, the Fuellox unit may require a firmware update to ensure access to the latest features, bug fixes, and compatibility improvements.

The firmware updates are completed via the Fuellox Mobile App.

Preparation Checklist

Before updating, ensure you have the following:

• Fuellox Mobile App version 0.9650 or above
• Bluetooth proximity to the Fuellox device
• Approximately 10 minutes of available downtime (device will be offline)
• A user account with ‘Manage Devices’ and ‘Manage Firmware’ roles

Access to Roles

Access to firmware update roles is restricted.
Contact the Fuellox Help Desk to assign the necessary roles to your nominated user.

Note

This access is usually temporary and intended for authorised installers or service agents only.

When Should You Update?

The Fuellox team will inform you if a firmware update is necessary.

• They can walk you through the process during a remote session if needed.
• In some cases, your reseller or service technician may perform the update on-site (service charges may apply).

How to Update the Firmware

Read this guide thoroughly before starting. Follow these steps carefully to update the firmware. The following images are taken from an Android device (iOS is visually identical):

1. Manage Device Menu
   Open the Fuellox Mobile App and log in as usual.
   Go to ☰ Menu → Manage Devices.

   

2. Connect to a Device
   On the Manage Device page, locate your Fuellox unit and connect via Bluetooth.

   

3. Details Screen
   Once connected, check the firmware version displayed on the Details screen.
   If the version is already 0.20, no update is required — you can stop here.

   

4. Configuration Screen
   Navigate to the CONFIG tab within the connected device.

   

5. Update Firmware
   Tap the Update Firmware button.
   Select the target firmware version (e.g., 0.20) and tap Update Device.

   If prompted to PAIR, accept the request to initiate the update.
   The firmware will now transfer via Bluetooth.

   Note

   Keep your mobile device near the Fuellox unit during the transfer:

   • Do not close the app or move out of range.
   • File transfer takes 4–8 minutes.
   • It may take a few seconds to begin.

   

6. Update Commenced
   The firmware transfer has started.

   Contact the Help Desk to verify that the new firmware version is active once the update completes.
   If the transfer fails or is corrupted, Fuellox will automatically revert to the previous version for safety.

   

7. Update Complete
   Once the transfer is complete, the device will reboot automatically.
   Perform a manual power cycle:

   • Turn the device off
   • Wait 20–30 seconds
   • Turn the device back on

   Then perform a test transaction to confirm successful operation.
