Overwrite the characters with your desired name.
Unlike premium Bluetooth modules (such as the Qualcomm CSR8645 or HC-05) that feature dedicated UART pins for AT command configuration, the standard VHM-314 does not officially support AT commands over a serial connection. The default firmware is compiled with a hardcoded string for the Bluetooth name, which is flashed onto the chip during manufacturing. Consequently, changing the name cannot be accomplished via a simple software switch or a button combination.
Many modern operating systems (including Android, iOS, Windows, and Linux/Raspberry Pi OS) allow you to set a local "Alias" or "Nickname" for paired Bluetooth MAC addresses.
Ensure your module is powered off. You will need to locate the RX and TX pins on your VHM-314 board. Use a tool like the OVC3860 Development Tool or a similar serial terminal. Connection:
This method carries a high risk of bricking the device. It requires micro-soldering tools, a USB-to-TTL serial adapter, and proprietary Chinese chip utilities. Tools Needed A USB-to-UART/TTL serial adapter (CP2102 or FT232RL). High-quality soldering iron and thin gauge wire. Vhm-314 Change Name
Many VHM-314 boards use "AC" series chips (e.g., AC20BP) which require proprietary SDKs to modify. Alternative Solutions for Device Identification

The VHM-314 is a highly popular, low-cost Bluetooth audio receiver board used extensively by DIY electronics enthusiasts. It allows users to convert vintage amplifiers, wired headphones, or car stereos into wireless sound systems. However, a common frustration with this board is its default Bluetooth broadcast name, which usually appears as "XY-BT" or "VHM-314." When deploying multiple boards in a single household, identifying the correct device becomes difficult.
Typical specifications include:
No number. No suffix. No permission.
JieLi standard flashing/debugging tool (often called "JL Isptool" or the "JieLi Bluetooth Burning Tool"). Step-by-Step Process:
Use programmer software (like NeoProgrammer or AsProgrammer) to read the contents of the EEPROM and save a backup file.

If the technical barrier or tool cost of editing the firmware is too high, consider these practical workarounds:
Open the Control Panel, go to Devices and Printers, right-click the VHM-314, select Properties, and change the name under the Bluetooth tab. Consequently, changing the name cannot be accomplished via
