Open the saved binary file in a hex editor like HxD.
Disconnect the programmer, power up the VHM-314, and scan for Bluetooth devices on your phone to verify the new name.

Once the alias is set, force a propagation event to update downstream nodes. Vhm-314 Change Name
To help me give you the best advice for your project, let me know:
Open NeoProgrammer, click "Detect" to identify the chip type, and click "Read IC" . Once the read completes, click "Save" to backup the original firmware as a .bin file. Never skip this step; you will need this backup if the chip data becomes corrupted.
If the board responds with OK , you can change the name using the proprietary syntax for that specific firmware package. Typically, the command structure follows one of these formats: AT+NAME=YourCustomName Use code with caution. AT+BNAME=YourCustomName Use code with caution.

A USB-to-TTL serial adapter (such as a CH340 or CP2102 board). A soldering iron and thin jumper wires. A computer running Windows. Software Needed: JieLi AC69xx SDK (Software Development Kit).
Modifying the broadcast name of the VHM-314 requires a bit of technical workaround, as the board does not feature a user-friendly software interface or built-in configuration buttons.
The is a popular, low-cost Bluetooth 5.0 audio receiver module used for DIY speaker projects and car audio upgrades. While highly functional, users often want to change its default broadcast name—typically "XY_BT" , "VHM-314-V2.0" , or "BM3" —to something more personalized or to distinguish between multiple modules.

One of the most frustrating aspects of the VHM‑314 is that even its default name is inconsistent. Different vendors, different batches, and different firmware versions cause the module to broadcast a variety of names. Here is a sample of what users have reported:
If you lack the soldering equipment, programmers, or technical background required to execute the steps above, changing the firmware directly may not be viable. Consider these alternative workarounds:
