To check your scale's current firmware, open the "Acaia Updater" app and establish a connection with your scale. You'll know the connection is successful when the app shows the real-time weight displayed on your scale. Once you've connected your scale via Bluetooth, the app will display the current firmware version.
The app will then automatically download the latest firmware available. Once the download finishes, click on "Next."
Position your phone near or on top of your Acaia device and establish the connection.
The app will inform you of your current firmware version and prompt you to proceed by clicking "Next."
After selecting "Next," the app will initiate the firmware transfer process, and your device will enter update mode (avoid turning it off during this process).
Once the firmware update is complete, your screen will show a "Done" button. Now, you're ready to resume your brewing activities!
