To understand how to change the name, you must first look at the components on the board. The VHM-314 is built around a highly integrated Bluetooth system-on-chip (SoC), typically from the JieLi (JL) AC69xx series (such as the AC6925A or AC6921A).

To change the name of a VHM-314 board, you must first identify the specific integrated circuit (IC) powering your exact module. Because these boards are manufactured by various open-source component factories in Shenzhen and distributed globally under the same "VHM-314" umbrella name, the onboard microcontroller/Bluetooth SoC (System on Chip) can vary across production batches. The most common chipsets found on the VHM-314 include: Vhm-314 Change Name
Method 2: AT Commands via Bluetooth or UART (Firmware-Dependent)
The QA team subjected VHM-314 to regression testing. The following edge cases were verified: To understand how to change the name, you
Inspect the underside or periphery of your VHM-314 board. Look for unpopulated copper solder pads labeled , RX , GND , and 5V (or VCC). If these labels are missing, you must locate the datasheet for the specific JieLi chip revision on your board to identify the UART debugging pins directly on the chip legs. 2. Wire the Interface
While changing the broadcast identity of a VHM-314 requires a bit of hands-on technical effort, it elevates your custom audio builds to a professional standard. Utilizing either a basic USB-to-UART adapter or a hardware flash programmer unlocks complete control over this high-utility, budget-friendly Bluetooth module. Because these boards are manufactured by various open-source
