Connect the adapter's to the board's RX and vice versa (if the board has exposed serial pads).
Modifying the Bluetooth broadcast name on a VHM-314 requires altering the data stored inside its onboard flash memory or microcontroller. Because the board lacks a native USB data interface or a companion smartphone app for configuration, changing the name demands a technical approach. Understanding the Hardware Limitations

Plug the USB-to-UART adapter into your computer and ensure the appropriate driver (e.g., CH340 or CP210x driver) is installed. Note the assigned COM Port number in your OS Device Manager. Vhm-314 Change Name
If you need a Bluetooth device that allows you to change its broadcasting name permanently, consider upgrading to a module based on the CSR8645 or a similar programmable platform. If you are struggling with a specific step, let me know: are you connecting to? (Android, iOS, PC) What is the current name showing? I can provide more tailored steps.
Type your preferred alternative title directly into the text field at the top, then hit and OK . Connect the adapter's to the board's RX and
Within the SDK configuration utility, navigate to the Bluetooth settings tab. Locate the field labeled "Local Name" or "Bluetooth Name". Change "VHM-314" to your desired custom name.
Unlike high-end Bluetooth modules (like those from CSR/Qualcomm) or programmable microcontrollers (like the ESP32), the VHM-314 uses a low-cost, fixed-function Bluetooth SoC (System on a Chip). In most versions of this board, the Bluetooth name is hardcoded into the firmware during the manufacturing process. The Technical Barrier Note the assigned COM Port number in your OS Device Manager
