If your module uses a CSR chip, you will need a or a dedicated CSR USB-SPI programmer . Connect the module to your PC via the programmer. Use software like PSTool (BlueSuite) . Filter for "Local device's 'user friendly' name" . Enter your new name and click Set . Method B: AT Commands (Standard Modules)

Method 3: Software Masking via the Host Device (The Easy Way Out) By following the guidelines and best practices outlined

The primary issue is that the VHM-314 can appear under various names when discovered by a smartphone, tablet, or computer. There is no standard or guaranteed naming convention across different manufacturers. Your VHM-314 module might appear as any of the following when you scan for Bluetooth devices:

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.

If your VHM-314 utilizes a JieLi (JL) processor, the most reliable and permanent method to change the Bluetooth name is using the manufacturer's proprietary development environment. This requires hardware tools to interface directly with the chip’s programming pins. Tools Required:

To understand how to change the name, you first need to understand the hardware. The VHM-314 is built around a main system-on-a-chip (SoC), typically from the JieLi (JL) AC69xx series (such as the AC6925 or AC6926).

Open the JieLi assembly/configuration software on your PC. Load the standard configuration profile ( .cfg or .bin file) that matches your chip series.

Flashing incorrect firmware variants or interrupting a write process on JieLi microcontrollers can permanently corrupt the chip's bootstrap loader, rendering the VHM-314 permanently non-functional. Given the low price point of the module, hardware flashing is primarily pursued as an educational exercise or for commercial scaling.
