If your goal is simply to avoid confusing multiple boards in your own home, you can rename the device directly within your smartphone or computer settings. This changes how the device appears only on that specific host device, requiring zero hardware modifications. On Windows 11 / 10
The core chip in many VHM-314 modules is the . The general process involves:
If the configuration tool cannot read your specific board, you may need to compile or source a pre-modified firmware binary ( .bin or .bfu file) and flash the entire memory chip. Step-by-Step Instructions
Tap the next to the connected "VHM-314" device profile. Tap the Edit/Pencil icon in the top right corner. Input your custom name and hit Save . On Apple macOS: Open System Settings and go to Bluetooth . Vhm-314 Change Name
Inspect your VHM-314 board closely. Look for tiny unpopulated copper pads labeled TX , RX , GND , and 5V (or VCC).
JieLi chips can often be put into a USB mass storage or debugging mode when connected to a PC via the onboard USB port or specific data pads (DP and DM). Overview of the Process:
Click the "Write" , "Burn" , or "Update" button in the software utility. The software will push the updated configuration sector back to the chip's memory. If your goal is simply to avoid confusing
By following the guidelines and best practices outlined in this article, you can successfully change the name of your VHM-314 device and improve its functionality and usability in your network.
Some variants of the VHM-314 feature an auxiliary 24C02 EEPROM chip on the board, or the main JieLi chip emulates one. If your specific board revision reads configuration data from an external EEPROM chip, the Bluetooth name can be altered by rewriting the hex values inside that chip.
These chips store configuration parameters—including the Bluetooth Device Name (Local Name), volume levels, and pairing codes—inside a small configuration sector of their internal flash memory or an adjacent 8-pin external EEPROM chip (often a 24C or 25-series variant). The general process involves: If the configuration tool
