To understand how to change the name, you first need to understand the hardware. The VHM-314 is built around a main system-on-a-chip (SoC), typically from the JieLi (JL) AC69xx series (such as the AC6925 or AC6926).
“My name,” she said, loud enough for the crack in the dome to carry it outside, “is Elara.”
The easiest way to alter the displayed Bluetooth name without hacking the VHM-314 hardware is to bypass its Bluetooth transmitter entirely using an external transceiver module. How It Works
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. Vhm-314 Change Name
Before we dive into the process of changing the name, it's essential to understand the naming conventions used in the VHM-314 system. The naming convention typically consists of a combination of letters and numbers that uniquely identify a specific component or configuration.
If you need the name to change for everyone who sees the device, you must reprogram the onboard chip (often a CSR-based chip). This requires specialized hardware and technical skills.
If your board supports AT commands over serial, attach your USB-to-TTL adapter to the board's TX/RX pins, open a serial terminal emulator (such as PuTTY, Tera Term, or Arduino Serial Monitor) on your PC, and configure the serial settings to: 9600 or 115200 (most common) Data Bits: 8 Parity: None Stop Bits: 1 Once connected, send the testing command: AT Use code with caution. To understand how to change the name, you
Once swapped, you can simply plug these alternative modules into a computer via a USB-to-UART module, open a serial terminal (like PuTTY), and type a simple command like AT+NAME=MyCustomSpeaker to instantly change the broadcast identity.
Most modern smartphones, tablets, and computers allow you to rename paired Bluetooth devices locally. While the VHM-314 will still broadcast its original name to the world, it will display as your chosen nickname on your personal device.
If your goal is simply to stop getting confused when connecting your phone, follow these steps: For Android: Go to > Connected Devices . Tap the Gear Icon next to the VHM-314. Tap the Pencil Icon (Edit) at the top right. Type your new name (e.g., "Retro Radio") and hit Rename . Go to Settings > Bluetooth . Tap the "i" icon next to the VHM-314. Tap Name . Enter the new name and go back to save.

While it is a powerful little board, changing its broadcast name is not a standard feature you'll find in a settings menu. Here is everything you need to know about the possibility of a "VHM-314 Change Name" project. The Reality of Renaming the VHM-314 For most users, the short answer is that the does not support easy renaming
For users seeking a zero-risk setup, software aliasing provides the exact same visual result on your primary devices without touching a soldering iron. For advanced developers and makers building commercial products out of the VHM-314, setting up a JieLi flashing environment or editing the 24C02 EEPROM is the only way to hardcode a permanent identity directly onto the hardware.
