1. Navigation & system

Exit: Closes the settings menu and returns to the main weighing screen.

About: Displays system information including the current firmware version, compilation time, and unique compilation ID.

Show logo: Displays the boot logo on the screen (ideal for product photography).

2. Device settings & customization

Calibration: Recalibrates the scale accuracy. Requires a single reference weight of either 50g, 100g, 200g, 500g, or 1000g.

Flip screen (on/off): Rotates the screen display 180° for alternative physical positioning.

Timer on top / weight on top: Toggles the layout preference to display either the timer or the weight on the top row of the screen.

3. Connectivity & Bluetooth (BLE)

Button with BLE (enable/disable):

Enable: Keeps physical buttons active during a wireless connection.

Disable: Locks physical buttons while connected to prevent accidental inputs.

Heart beat (on/off):

On: Automatically disconnects the scale if the app loses connection, allowing for faster reconnection.

Off: Mandatory for legacy, third-party apps that do not support the heartbeat signal to prevent accidental disconnections.

4. WiFi settings

WiFi on/off: Enables or disables wireless networking.

Note: Requires a power cycle (off/on) after activating to broadcast the local hotspot and display the WiFi icon.

WiFi Status: Displays current network diagnostics, including status, SSID name, and assigned IP address.

Reset WiFi: Clears existing network configurations and resets the WiFi status.

5. Power & performance

Auto sleep (on/off):

On: Shuts down the scale after 15 minutes of inactivity (only when disconnected from BLE) to preserve battery.

Off: Keeps the scale powered indefinitely until manually turned off or the battery dies.

Quick boot (on/off):

On: Boots the scale instantly with a brief touch of any button.

Off: Requires a long press to power on, preventing accidental activation inside travel bags or on crowded countertops.

Drift Comp (Off / 0.05g / 0.75g / 0.1g / 0.2g): Corrects minor weight fluctuations caused by rising electronic temperatures or environmental heat.

Recommended: 0.05g or 0.075g for general espresso use.

Pour-over: 0.1g or 0.2g to counteract ambient heat drift from large carafes of hot water.
