Vhm-314 Change | Name

Instead of using the VHM-314 to handle the wireless connection, you use it strictly as a wired digital-to-analog converter (DAC) or audio amplifier stage. You introduce a secondary, highly configurable Bluetooth module (such as the or an HC-05/06 modified for audio) to handle the wireless reception. Step-by-Step Implementation

An SOIC8 test clip (to read the chip without unsoldering) or a soldering iron.

Do you see any labeled TX, RX, or PRG on the back of the board?

Run a connectivity test against the new name to ensure the handshake is successful.

Save the edited hex file, burn it back onto the SPI flash chip using the programmer, and solder the chip back onto the VHM-314 board. Alternative Solutions (If Reprogramming is Unfeasible) Vhm-314 Change Name

This method carries a high risk of bricking the device. It requires micro-soldering tools, a USB-to-TTL serial adapter, and proprietary Chinese chip utilities. Tools Needed A USB-to-UART/TTL serial adapter (CP2102 or FT232RL). High-quality soldering iron and thin gauge wire.

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:

The VHM-314 is a highly popular, low-cost Bluetooth audio receiver board used extensively by DIY electronics enthusiasts. It allows users to convert vintage amplifiers, wired headphones, or car stereos into wireless sound systems. However, a common frustration with this board is its default Bluetooth broadcast name, which usually appears as "XY-BT" or "VHM-314." When deploying multiple boards in a single household, identifying the correct device becomes difficult. Instead of using the VHM-314 to handle the

Open the (classic view) and go to Devices and Printers . Right-click the VHM-314 icon and select Properties . Go to the Bluetooth tab.

Read the laser-etched markings on the main IC to find the exact JieLi chip model.

Attach a SOIC8 test clip to the chip, or desolder the chip and place it into a CH341A programmer. Connect the programmer to your PC.

Changing the VHM-314 Bluetooth module name is not supported directly, but users can rename it on specific devices via Bluetooth settings in Android, iOS, or Windows. A permanent, module-wide rename requires advanced firmware modification using tools like CSR BlueSuite to edit the device name, which involves potential risk of damaging the board. For a detailed guide, see the instruction manual at Manuals.plus . Changing the name on a CSR A64215 audio bluetooth module Do you see any labeled TX, RX, or

What you primarily connect to it? Your comfort level with soldering and firmware tools ?

If having a custom broadcast name is a dealbreaker for your project, you might consider modules that use chips with accessible AT commands or SPI programming capabilities, such as: Changing the name on a CSR A64215 audio bluetooth module

The short answer for most VHM-314 users is . Unlike a smartphone or a high-end Bluetooth speaker, the VHM-314 is a simple, no-frills device. It does not have a user-accessible interface or support for the AT commands that would allow you to modify its core identifier. As the Raspberry Pi Official Magazine notes, "it's not usually possible to change the name of them". The firmware on these cheap modules is generally locked, and the manufacturer's only priority is low-cost production.

Some VHM‑314 variants store their firmware on an external SPI flash chip (an 8‑pin SOIC‑8 package next to the main processor). If your board has that chip, you can use a hardware programmer (like a TL866 or CH341A) to read the flash contents, search for the Bluetooth name string in the hex dump, overwrite it with a new name of the same length, and then write the modified firmware back to the flash. One blog post about domesticating a Bluetooth speaker’s firmware used exactly this approach to change notification sounds, but the author noted that is the hardest part.
