Below is a comprehensive guide on how the VHM-314 manages its data and the steps required to change its Bluetooth device name. Understanding the VHM-314 Hardware Architecture
Send the AT Command AT+NAME[NewName] (e.g., AT+NAMEMySpeaker ).
If you download the source code, open the main configuration header file (usually named board_config.h or app_config.h ) using a text editor or the JieLi IDE.
Rather than a hard rename, it is often best practice to create an alias. This allows the system to recognize both the old and new names during the transition period, preventing service interruption. Vhm-314 Change Name
Warning: This method carries a high risk of bricking the board if the wrong firmware version is flashed. Method 2: The Hardware Swap (The Intermediate Alternative)
: Go to Settings > Bluetooth , tap the gear icon next to the connected VHM-314, and select "Rename" .

The VHM‑314 is a product of the global low‑cost electronics ecosystem. It is manufactured by several different Chinese companies (Zhanrui Electronics, Shenzhen Qianhai Ku Xian Sheng Industrial, and others). These companies are not incentivised to add user‑configurable naming; the module’s selling point is its price, not its features. As long as the VHM‑314 continues to be sold for under $5, it is highly unlikely that any manufacturer will invest the engineering effort to add a configuration interface.
Archaic’s voice slithered into her auditory cortex: “Unrecognized vocalization. Please state your new identifier for permanent registry. You have thirty seconds.”
These SoC architectures store configuration data—including the Bluetooth device name, audio prompts, volume curves, and LED behavior—inside either an internal flash memory area or an external serial peripheral interface (SPI) flash memory chip (often an 8-pin IC located adjacent to the main processor). Rather than a hard rename, it is often
To change the broadcast name permanently (so it shows up as "My Custom Speaker" for everyone), you must use hardware tools. The VHM-314 typically uses an (like the AC208 or AC1847).
For VHM‑314 users, there are several practical reasons to change the device’s name:
