| Myth | Fact | |------|------| | “Vhm-314 was banned, so they changed the name.” | Not a ban—primarily trademark and FDA compliance issues. | | “The new name is just a marketing gimmick.” | No; legal and safety reasons drove the change. | | “Vhm-314 is now called Phenylpiracetam Hydrazide.” | False. That is a different compound. NMCNA-7 is correct. | | “The chemical structure has changed.” | The structure is identical; only the identifier has changed. | If you share with third parties, their policies apply

Because the name is hardcoded into the firmware memory, you cannot change it via standard Bluetooth commands from your phone. It requires modifying the binary data stored on the chip.

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)

The quest to change the Bluetooth name of a VHM-314 module is a journey that ends where it begins: with a simple, practical solution that works on your phone or PC. While a permanent, device-level name change is currently out of reach for the average user due to the hardware's design, the local renaming workaround is so effective that it makes the underlying limitation a non-issue for almost any project.
