There are several reasons why you might want to change the name of your VHM-314 device. Here are a few:
While this does not change the broadcast name transmitted by the VHM-314 hardware to the outside world, it changes how the name is displayed on your personal screen, resolving any identity confusion. On Windows 10/11: Connect your PC to the VHM-314 via Bluetooth.
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. Vhm-314 Change Name
If your VHM-314 variant features a dedicated 8-pin external memory chip next to the main Bluetooth IC, you can modify the name by dumping, editing, and reflashing the memory chip. Tools Required: An EEPROM/Flash programmer (e.g., CH341A programmer).
This is the universally recommended solution for anyone with multiple VHM-314 boards. Instead of changing the module, you change how your phone or computer displays its name. This renaming is stored locally on your device, so the module itself remains unchanged, but you can easily identify it. There are several reasons why you might want
The is one of the most popular, cost-effective Bluetooth 5.0 audio receiver boards available for DIY audio projects, car stereo upgrades, and custom Bluetooth speaker builds. By default, this ultra-compact decoder board broadcasts its SSID as "XY_BT" . While this default designation works perfectly fine for single-device setups, running multiple custom audio systems in the same household or trying to commercialize a custom audio product makes changing that generic broadcast identifier essential.
Power up the VHM-314 by connecting its 5V/GND pads to the adapter, or via its built-in Micro-USB/USB-C port. Click the "Read" or "Connect" button in the software. If successful, the software will populate fields showing the current configuration, including the name "VHM-314". The VHM-314 is a highly popular, low-cost Bluetooth
Open the JieLi assembly/configuration software on your PC. Load the standard configuration profile ( .cfg or .bin file) that matches your chip series.
Unlike modules like the or HC-06 , which use AT Commands to change internal settings like name and PIN, the standard
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.
Save the edited file under a new name. Return to your programmer software, open the modified .bin file, and click "Write IC" (or "Program" ).
