And if you are one of the brave few who still wants to try hacking the firmware… the JieLi reverse‑engineering community always welcomes new contributors. Just be prepared for a steep learning curve and the real possibility that you might turn your $2 module into a tiny, useless piece of e‑waste.
If you are running multiple boards in the same house or building a custom Bluetooth speaker, changing this broadcast name is essential to avoid connection confusion. Because the VHM-314 lacks an onboard microcontroller UI or an official companion app, changing its name requires interacting directly with its onboard EEPROM or flash memory chip using external hardware. Vhm-314 Change Name
A USB-to-TTL UART serial adapter (such as a CH340, CP2102, or FTDI board). And if you are one of the brave
These chips store configuration parameters—including the Bluetooth Device Name (Local Name), volume levels, and pairing codes—inside a small configuration sector of their internal flash memory or an adjacent 8-pin external EEPROM chip (often a 24C or 25-series variant). Because the VHM-314 lacks an onboard microcontroller UI
