Vhm-314 Change Name

For the truly dedicated, it is technically possible to change the name by dumping and modifying the firmware of the Bluetooth chip. This is a complex process that requires specialized hardware, software, and significant technical expertise.

Some variants of these modules support AT commands if you connect a serial bridge (like an Arduino) to the TX/RX pins. AT+NAME[NewName] Response: The module should return OK if successful.

Do you have any available, such as a USB-to-TTL adapter or a CH341A programmer? Are you comfortable using a soldering iron ? Share public link

Use programmer software (like NeoProgrammer or AsProgrammer) to read the contents of the EEPROM and save a backup file. For the truly dedicated, it is technically possible

Be cautious when attempting firmware changes; incorrect settings can "brick" the module, making it unable to connect.

The flash chip may be write‑protected. The checksum inside the firmware might become invalid, causing the module to refuse to boot. And if the chip is not an external flash but instead is embedded inside the main chip (a “mask ROM” or internal flash), dumping is impossible without expensive equipment.

| Reported Bluetooth Name | Source / Version | Notes | |------------------------|------------------|-------| | XY_BT | Most common default | Used on many “XY‑BT” labelled boards; also documented by multiple sellers. | | VHM-314 | Basic generic name | Listed as the device name in many product descriptions. | | VHM-314-V3.0 | V3.0 version | Official Bluetooth name for the V3.0 board (with EQ and IR control). | | XIDADIANZI | An actual module tested by Raspberry Pi Magazine | The seller claimed the name would be ‘XY_BT’, but the real unit broadcast ‘XIDADIANZI’. | | BT-Speaker | Some generic variants | Used on boards that have been rebadged by third‑party sellers. | | Bluetooth Device | Fallback when no custom firmware present | Some very cheap clones fall back to a bare‑bones system name. |

" to "Living Room Audio"), you must use a physical connection to the module's controller chip.

The implementation under ticket VHM-314 addresses the requirement to modify user entity display names within the system. The feature is a critical Quality of Life improvement that has been highly requested by the user base. Overall, the execution is functional and meets the primary acceptance criteria, though there are minor UI/UX considerations that should be addressed before full deployment.
