Please ensure the weighing scale enabled with Bluetooth connection/RS-232 and continuous data transmission.

Bluetooth SPP (Classic) or BLE (Low Energy)

Ensure the scale is enabled with a Bluetooth connection and supports continuous data transmission.

USB Serial RS-232 (Alternative to Bluetooth)

WAISCALE BTS supports USB to serial converter chips:

• FTDI FT232R, FT232H, FT2232H, FT4232H, FT230X, FT231X, FT234XD
• Prolific PL2303
• Silabs CP2102, CP210*
• Qinheng CH340, CH341A, CH9102

If devices are not displayed in the app, it could be due to an issue with the Android device, such as the phone not supporting USB Host Mode (OTG), the USB to Serial RS-232 converter cable, or a combination of both. Automatic startup of this app and automatic driver selection are only supported for well-known USB VID/PIDs that are compiled into the app.
