Vhm-314 Change Name -
The VHM-314 is a popular, low-cost Bluetooth audio receiver module used extensively in DIY audio projects. While these boards are efficient and easy to use, they often come with a generic broadcast name like "VHM-314" or "XY-BT."
Unfortunately, the makers of the VHM‑314 did not prioritise user‑friendly naming. As one Raspberry Pi Magazine article bluntly put it: “Our biggest complaint with cheap Bluetooth boards: it’s not usually possible to change the name of them.”
The short answer is The VHM‑314 was not designed with user‑configurable naming in mind. Here is why:
typically appears as or "BT-Audio" in your device's Bluetooth discovery list. This is hard-coded into the board's firmware and cannot be changed by simply pressing a button on the module itself . 2. Renaming on Your Device (Soft Change) Vhm-314 Change Name
Changing the name of your VHM-314 device is a simple process that can be completed in a few steps. By following the guidelines outlined in this article, you can personalize your device and make it more identifiable in your network. Remember to choose a descriptive name, avoid special characters, and keep it short. If you encounter any issues during the process, consult with your system administrator or refer to the troubleshooting tips outlined in this article.
The quest to change the Bluetooth name of a VHM-314 module is a journey that ends where it begins: with a simple, practical solution that works on your phone or PC. While a permanent, device-level name change is currently out of reach for the average user due to the hardware's design, the local renaming workaround is so effective that it makes the underlying limitation a non-issue for almost any project.
is a low-cost, fixed-function board, and changing its internal name is not natively supported through simple user settings or its standard USB port. Option 1: Device-Side Renaming (Recommended) The easiest way to "change" the name is to do it on the receiving device The VHM-314 is a popular, low-cost Bluetooth audio
The event was not a simple branding update. Several converging factors led to the decision, each carrying significant legal, scientific, and commercial weight.

More sophisticated Bluetooth modules (such as those based on the HC‑05 or HC‑06 chips) support an “AT command set” that allows you to send text commands over a serial interface to change parameters including the device name. The VHM‑314 is not one of those modules. While some product pages mention that “the MODE pin can be used to change between different audio profiles (AT commands required),” those commands relate to audio behaviour (codec selection, pairing behaviour), not to renaming the device. No publicly documented AT command for changing the Bluetooth broadcast name has ever been found for the VHM‑314 series.
To understand how to change the name, you must first look at the components on the board. The VHM-314 is built around a highly integrated Bluetooth system-on-chip (SoC), typically from the JieLi (JL) AC69xx series (such as the AC6925A or AC6921A).
| Module | Approx. Price | Name Change Method | Notes | |--------|---------------|--------------------|-------| | | $6–8 | AT command AT+NAME=newname | Originally designed as a data module, but can be used for audio with the right firmware. Requires a serial adapter. | | DFRobot Bluno series | $20–30 | AT commands via USB or Bluetooth | Much more expensive, but fully configurable and Arduino‑compatible. | | ESP32‑based boards (with A2DP sink firmware) | $5–10 | Set bt_device_name variable in Arduino code | The ESP32 is a full microcontroller; you write your own Bluetooth audio receiver and can assign any name you like. Extremely flexible but requires programming. | | KRC‑86B | $10–15 (discontinued) | Not user‑configurable | An older option that the VHM‑314 largely replaced due to availability and price. | Here is why: typically appears as or "BT-Audio"
