Change Name - Vhm-314
is its fixed, broadcasted Bluetooth ID—typically showing up on your phone or PC as or "XY-BT" . If you are building multiple audio projects or want a cleaner user experience, you will likely find yourself searching for a change name solution.
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.
On the surface, renaming a Bluetooth device sounds like a trivial feature. In most modern Bluetooth gadgets—headphones, speakers, smart watches—you can tap a button in the settings menu and give the device any name you like. Why should a Bluetooth receiver be any different? Vhm-314 Change Name
Unplug the module from your computer. Power it up independently using a phone charger or battery setup. Turn on Bluetooth on your smartphone and scan for new devices to verify that your custom name appears. Method 2: Direct EEPROM/Flash Programming (Hardware Method)
Plug the USB-to-UART adapter into your computer and ensure the appropriate driver (e.g., CH340 or CP210x driver) is installed. Note the assigned COM Port number in your OS Device Manager. Instead of changing the module, you change how
Open the saved hex file in a Hex Editor (such as HxD). Use the text search function to find the default string, "XY-BT" or "VHM-314."
For the truly dedicated, it is technically possible to change the name by dumping and modifying the firmware of the Bluetooth chip. This is a complex process that requires specialized hardware, software, and significant technical expertise. proprietary software tools
If you lack the soldering equipment, proprietary software tools, or engineering background required to modify the VHM-314 firmware directly, the fastest and safest alternative is to use at the operating system level on your playback devices.
: Many versions of the VHM-314 lock the firmware , meaning serial pads might be disabled. If you cannot get an "OK" response after sending AT , the board may not support permanent name changes without specialized factory programming tools.
This guide covers the three primary methods to change the Bluetooth name on a VHM-314 board, ranging from non-invasive hardware bypasses to advanced chip reprogramming. Method 1: The Codec Bypass (No Programming Required)
new devices, you must interface directly with the module's chip using specialized hardware.
