Vhm-314 Change Name !!install!! < RELIABLE - CHEAT SHEET >

If you want to try modifying your board, I can help you figure out the exact steps. Could you tell me is printed on your board, whether it has an external 8-pin chip , and if you own an EEPROM programmer ? Share public link

Open the saved binary file in a hex editor like HxD.

If you are stuck with several VHM‑314 modules and cannot rename them, there are a few practical workarounds:

The Bluetooth name, device configuration, and firmware are stored directly on this chip or an adjacent surface-mount EEPROM/Flash memory chip. Because these chips are designed for mass-production consumer goods, they are hardcoded at the factory. There is no native USB-to-serial command line interface (like AT commands used in HC-05 modules) available on standard VHM-314 boards out of the box. Vhm-314 Change Name

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:

Many users find that modifying these boards or adding resistors (like a 220-ohm or 2.1K Ω resistor) can help eliminate static background noise. Volume Issues:

If having a custom broadcast name is a requirement for a commercial product or a high-end DIY build, consider swapping the VHM-314 for a module that supports . Recommended Alternatives:

Are you tired of using the default name for your VHM-314 device? Perhaps you're looking to personalize it or make it more identifiable in your network. Whatever the reason, changing the name of your VHM-314 device is a straightforward process that can be completed in a few simple steps. If you want to try modifying your board,

Disconnect the programmer, power up the VHM-314, and scan for Bluetooth devices on your phone to verify the new name.

A (CH340G, FT232RL, or CP2102). A soldering iron and fine hookup wire. A Windows PC.

This method is perfect for 99% of users. It instantly solves the identification problem.

Run a connectivity test against the new name to ensure the handshake is successful. The name change request has been submitted to

Always back up your current settings before writing new data, as an incorrect flash can "brick" the module.

The board lacks a dedicated USB-to-UART interface for AT commands.

Within the software UI, navigate to the "Bluetooth Settings" or "Local Name" field. Replace the default text string "VHM-314" with your desired custom name (e.g., "Living Room Audio" ). Ensure the string length matches the maximum byte constraints allowed by the firmware (typically under 20 characters to prevent buffer issues).

: For modules using Qualcomm/CSR chips, engineers use tools like BlueSuite or PSTool and a specialized CSR USB-SPI programmer to change the PSKEY_DEVICE_NAME . However, the VHM-314 often uses an AC69 series chip, which requires a specific "download tool" and proprietary hardware programmers rarely available to hobbyists.
