Vhm-314 | Change Name Portable

(your phone, tablet, or PC). This doesn't change the name for everyone, but it makes it easier for you to identify the module in your own list of paired devices. Settings > Bluetooth , tap the gear icon next to the , and select Settings > Bluetooth , tap the "i" next to the device, and select Control Panel > Devices and Printers , right-click the module, select Properties > Bluetooth tab , and enter a new name. Option 2: Technical Hardware Modification To permanently change the name so it appears differently to

True modification of the VHM-314 broadcast name requires modifying the onboard ROM or EEPROM memory of the master system-on-chip (SoC). This module typically utilizes a .

Save the edited file under a new name. Return to your programmer software, open the modified .bin file, and click "Write IC" (or "Program" ).

Save the modified binary file. Use the programming software to erase the external flash chip and write the new modified file onto it.

Open the JieLi configuration utility on your PC. These proprietary tools feature a graphic user interface (GUI) dedicated to editing fixed chip parameters: Power on the VHM-314 via the USB adapter. Vhm-314 Change Name

Turn on Bluetooth and pair with the VHM-314 (default name "XY-BT").

Connect the adapter's to the board's RX and vice versa (if the board has exposed serial pads).

Use a dedicated chip programmer (like the cheap and versatile CH341A programmer ) paired with an SOIC8 test clip. Clamp the clip onto the VHM-314’s memory/MCU chip, load the binary file into the programming software (e.g., AsProgrammer), and write the new firmware to the chip. Method 3: Hardware Modification (Advanced)

Plug the USB-to-UART adapter into your computer and ensure the appropriate driver (e.g., CH340 or CP210x driver) is installed. Note the assigned COM Port number in your OS Device Manager. (your phone, tablet, or PC)

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:

If the technical barrier or tool cost of editing the firmware is too high, consider these practical workarounds:

Examine the VHM-314 PCB for unpopulated solder pads labeled TX, RX, DM, DP, or direct test points connected to the main chip.

Method 3: Software-Based Aliasing (The Practical Workaround) Return to your programmer software, open the modified

The short answer is The VHM‑314 was not designed with user‑configurable naming in mind. Here is why:

and specific software to modify the internal firmware settings. Step-by-Step Customization

| Feature | Details | |---------|---------| | Bluetooth version | 4.1, 4.2, or 5.0 (depends on variant) | | Power supply | 3.7 V – 5 V (USB or Li‑ion battery) | | Audio output | 3.5 mm stereo jack + solder pads | | Supported formats | MP3, WAV, APE, FLAC (lossless decoding) | | Signal‑to‑noise ratio | ≥ 90 dB | | Range | Up to 15 m |

The most direct, professional way to change the Bluetooth name is by rewriting the configuration data inside the JieLi microchip. This requires specialized hardware and software. Hardware Needed:
