Use programmer software (like NeoProgrammer or AsProgrammer) to read the contents of the EEPROM and save a backup file.
Overwrite the characters with your desired name.
If your project includes a microcontroller—such as an Arduino, ESP32, or Raspberry Pi—you can implement an electronic mask that rebrands how your master device interacts with the VHM-314, or use a micro-controller to intercept the pairing flow. Bluetooth Alias Mapping Vhm-314 Change Name
The announcement came through every pod’s neural patch: “Custodians, effective immediately, designation protocol Vhm is deprecated. You will select a new identifier. This identifier will be permanent.”
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. Bluetooth Alias Mapping The announcement came through every
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. VHM-314 Technical Overview Bluetooth Version: 5.0 Power Supply: 3.7-5V (Micro USB or battery pads) Audio Output: 3.5mm stereo jack or L/G/R solder pads LED Indicator: Long blue light (indicates connected state) Important Considerations
Turn your phone's Bluetooth off and on. Go to Bluetooth settings and click "Forget Device" on the old VHM-314 profile, then scan fresh. Conclusion It allows users to convert vintage amplifiers, wired
Navigate to the or String Configuration tab within the software. Locate the field labeled Device Name or BT_NAME .
True modification of the VHM-314 broadcast name requires modifying the onboard ROM or EEPROM memory of the master system-on-chip (SoC). This module typically utilizes a .
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.
