To get started, ensure that your Acaia Pearl scale is fully charged and install the "Pearl Updater" app from either the Apple App Store or Google Play Store.
Follow these step-by-step instructions:
1. Begin by turning on your Pearl Scale and letting it calibrate to zero as if you were preparing to use it.
2. Put your scale into weighing mode, which displays only the weight as 0.0. To do this, press and hold the power button to switch modes.
3. Launch the Pearl Updater app and tap on "Start."
4. The app will guide you through several information screens; read each one and tap "Next" to proceed.
5. Once you reach the "Firmware update" page, tap on "Select scale" and place your smartphone on top of the Pearl scale.
6. Your phone should detect the scale and display it as an option in the list, usually named "acaia scale." (If your scale is not detected after several attempts, it may have a Bluetooth connectivity issue.)
7. Once the scale is selected, the weight will appear on both the scale screen and the app. If they match, tap the "Update" button to send a prompt to the scale.
8. You'll be prompted to press the "T" button on the scale for 0.5 seconds to enter update mode. After doing so, return to the "Firmware update" page in the app and tap "Start Firmware Update" to begin installing the new firmware.
9. Once the app displays "complete," you're all set to go!
