Open the Control Panel , navigate to Hardware and Sound > Devices and Printers . Right-click the module, select Properties , go to the Bluetooth tab, and enter the new name. 2. Firmware-Level Renaming (Permanent)
Other practical workarounds include physically labeling each module with a marker, keeping careful documentation of which module is installed where, and—as a last resort—using a different Bluetooth module altogether. Several alternatives, such as the ESP32-A1S or the HM-10 , offer more customization.
: Go to Control Panel > Hardware and Sound > Devices and Printers . Right-click the device, go to Properties , and change the name in the Bluetooth tab. 2. Change the Firmware Name (Permanent)
If you are running multiple boards in the same house or building a custom Bluetooth speaker, changing this broadcast name is essential to avoid connection confusion. Because the VHM-314 lacks an onboard microcontroller UI or an official companion app, changing its name requires interacting directly with its onboard EEPROM or flash memory chip using external hardware.
The Bluetooth name, device configuration, and firmware are stored directly on this chip or an adjacent surface-mount EEPROM/Flash memory chip. Because these chips are designed for mass-production consumer goods, they are hardcoded at the factory. There is no native USB-to-serial command line interface (like AT commands used in HC-05 modules) available on standard VHM-314 boards out of the box. Vhm-314 Change Name
The VHM-314 is a highly popular, low-cost Bluetooth audio receiver module used extensively by DIY electronics hobbyists. Out of the box, the board broadcasts a generic Service Set Identifier (SSID) or Bluetooth name, typically . While this default name works perfectly for isolated testing, it becomes problematic if you deploy multiple modules in your home or build custom Bluetooth speakers for friends and clients.
Every Bluetooth module has a unique MAC address. If you have multiple "VHM-314" devices in one house, your phone or PC will usually list them as: VHM-314 (AA:BB:CC...) VHM-314 (DD:EE:FF...)
Request to change the official name on record for VHM-314.

By following the alias method and checking for referential integrity beforehand, you can resolve the VHM-314 ticket cleanly and keep your systems running smoothly.
The short answer is The VHM‑314 was not designed with user‑configurable naming in mind. Here is why:
Yes, modules like the ESP32-A1S, HM-10, or HC-05/HC-06 often support AT commands for customizing the Bluetooth name and other settings.
VHM-314 and the Power of a Name: Why Rebranding a Compound Matters Open the Control Panel , navigate to Hardware
Before attempting any hardware modifications, it is crucial to understand the chips powering the VHM-314. The board typically relies on one of two highly integrated Bluetooth audio SOCs (System on a Chip): (e.g., AC692X, AC695X) Asolid / Bluetrum chips
| Feature | Details | |---------|---------| | Bluetooth version | 4.1, 4.2, or 5.0 (depends on variant) | | Power supply | 3.7 V – 5 V (USB or Li‑ion battery) | | Audio output | 3.5 mm stereo jack + solder pads | | Supported formats | MP3, WAV, APE, FLAC (lossless decoding) | | Signal‑to‑noise ratio | ≥ 90 dB | | Range | Up to 15 m |
Method 1: Flashing the Chip via JieLi Development Tools (Advanced)
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. Right-click the device, go to Properties , and
