Unlike high-end Bluetooth modules (like those from CSR/Qualcomm) or programmable microcontrollers (like the ESP32), the VHM-314 uses a low-cost, fixed-function Bluetooth SoC (System on a Chip). In most versions of this board, the Bluetooth name is hardcoded into the firmware during the manufacturing process. The Technical Barrier

Modifying the Bluetooth broadcast name on a VHM-314 requires altering the data stored inside its onboard flash memory or microcontroller. Because the board lacks a native USB data interface or a companion smartphone app for configuration, changing the name demands a technical approach. Understanding the Hardware Limitations

Integrated directly inside the JieLi main IC.

This doesn't change the name on the chip itself, but it changes how it appears on your specific device.

After months of speculation on forums like Reddit’s r/Nootropics and Longecity, the official new designation for Vhm-314 has been confirmed by the primary Chinese and U.S.-based synthesis labs.

Before attempting to change the name of your VHM-314, keep the following risks in mind:

| Module | Approx. Price | Name Change Method | Notes | |--------|---------------|--------------------|-------| | | $6–8 | AT command AT+NAME=newname | Originally designed as a data module, but can be used for audio with the right firmware. Requires a serial adapter. | | DFRobot Bluno series | $20–30 | AT commands via USB or Bluetooth | Much more expensive, but fully configurable and Arduino‑compatible. | | ESP32‑based boards (with A2DP sink firmware) | $5–10 | Set bt_device_name variable in Arduino code | The ESP32 is a full microcontroller; you write your own Bluetooth audio receiver and can assign any name you like. Extremely flexible but requires programming. | | KRC‑86B | $10–15 (discontinued) | Not user‑configurable | An older option that the VHM‑314 largely replaced due to availability and price. |

Search for USER_NAME or the default device name within the PS (Persistent Storage) keys and modify it.

Many Bluetooth modules that transmit audio (like the HC‑05 used in Arduino projects) allow name changes because they expose a full UART command interface. The VHM‑314 is designed purely as a receiver – its only job is to receive and decode audio. Exposing a configuration interface would add cost and complexity that Chinese manufacturers deliberately avoided to keep the price under £2.

Method 2: Software Renaming via Host Controller (Advanced DIY)

Connect the TX and RX pads of the VHM-314 to the corresponding RX and TX pins of your USB-to-TTL adapter. Connect the ground (GND) pins together.

Connect your USB-to-TTL adapter to the board. The tool should display a "Connected" status once the module is powered on. Reading Values:
