Open the JieLi assembly/configuration software on your PC. Load the standard configuration profile ( .cfg or .bin file) that matches your chip series.
Read the laser-etched markings on the main IC to find the exact JieLi chip model.
The VHM-314 is a highly popular, low-cost Bluetooth audio receiver board used extensively by DIY electronics enthusiasts. It allows users to add wireless audio capabilities to old speakers, amplifiers, or car stereos. However, by default, the board broadcasts a generic Bluetooth name like "XY-BT" or "VHM-314." If you deploy multiple boards in your home or simply want a personalized tech setup, changing this broadcast name is a common goal.
The chip at the heart of most VHM‑314 boards belongs to the JieLi AC690X family. These chips are programmed at the factory with firmware that is typically A discussion on Hackaday noted: “When programmed there is some kind of key to lock them, [users] couldn’t reprogram them without that key.” Without the manufacturer’s proprietary toolchain and unlock keys, you cannot dump, modify, or re‑flash the firmware. Even if you could, the Bluetooth name is hard‑coded inside the firmware image, not stored in a separate user‑accessible EEPROM. Vhm-314 Change Name
allows for serial configuration, you can use a serial monitor (like PuTTY or Arduino Serial Monitor) set to 38400 baud, send AT+NAME followed by your new name, and AT+RESET to apply it.
Plug the other end of the clip adapter into the CH341A programmer, and plug the programmer into a USB port on your PC.
Change the value to your desired name, ensure the length is correct, and write the new value to the chip. Reboot: Power cycle the VHM-314.

Stick to basic alphanumeric characters (A–Z, 0–9) and avoid symbols or spaces when naming your device via AT commands or firmware files. Special characters can cause parsing errors in the underlying Bluetooth stack code, resulting in boot loops or a complete failure to advertise the Bluetooth beacon.

By following the guidelines and best practices outlined in this article, you can successfully change the name of your VHM-314 device and improve its functionality and usability in your network. The VHM-314 is a highly popular, low-cost Bluetooth
The short answer is The VHM‑314 was not designed with user‑configurable naming in mind. Here is why:
Method 3: Software-Based Aliasing (The Practical Alternative)
For VHM‑314 users, there are several practical reasons to change the device’s name:
Save the edited file under a new name. Return to your programmer software, open the modified .bin file, and click "Write IC" (or "Program" ).
