Name | Vhm-314 Change

The VHM-314 is a dedicated audio receiver board, not a sophisticated development board like an Arduino or ESP32. It lacks a user-accessible command interface or a standard method to reconfigure its core identity. The module is designed to be a simple, plug-and-play device. Once it has power, it boots up, loads its pre-programmed Bluetooth name from its flash memory, and begins broadcasting.

Inspect your VHM-314 board. Look for small test pads on the underside or edges labeled TX , RX , GND , and 5V (or VBAT ). Some variations of the board will break these out, while others require soldering directly to the incredibly small pins of the IC chip.

There are several reasons why you might want to change the name of your VHM-314 device. Here are a few:

Use programmer software (like NeoProgrammer or AsProgrammer) to read the contents of the EEPROM and save a backup file. Vhm-314 Change Name

Within the software UI, navigate to the "Bluetooth Settings" or "Local Name" field. Replace the default text string "VHM-314" with your desired custom name (e.g., "Living Room Audio" ). Ensure the string length matches the maximum byte constraints allowed by the firmware (typically under 20 characters to prevent buffer issues).

The VHM-314 is a highly popular, budget-friendly Bluetooth 5.0 audio receiver module frequently used in DIY audio projects. While excellent for adding wireless capabilities to speakers and amplifiers, it often comes with a generic, non-descript Bluetooth name like "BT-Audio" or similar.

Details:

Flashing incorrect firmware variants or interrupting a write process on JieLi microcontrollers can permanently corrupt the chip's bootstrap loader, rendering the VHM-314 permanently non-functional. Given the low price point of the module, hardware flashing is primarily pursued as an educational exercise or for commercial scaling.

Re-clip the chip, load your original untouched backup .bin file, and flash it back to factory defaults.

Open the (classic view) and go to Devices and Printers . Right-click the VHM-314 icon and select Properties . Go to the Bluetooth tab. The VHM-314 is a dedicated audio receiver board,

To change the name, you must overwrite this specific data segment. This is achieved either via a dedicated PC configuration tool connected through a USB-to-UART serial adapter, or by directly flashing the memory chip using an EEPROM programmer.

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

This is the universally recommended solution for anyone with multiple VHM-314 boards. Instead of changing the module, you change how your phone or computer displays its name. This renaming is stored locally on your device, so the module itself remains unchanged, but you can easily identify it. Once it has power, it boots up, loads

Most VHM-314 boards use a generic Chinese Bluetooth SoC (System on a Chip). To modify the internal firmware settings, you would typically need a USB-to-TTL Serial adapter (like a CP2102 or CH340) and specialized software like the OVC3860 Development Tool PSTool (for CSR chips) Complexity:
