Vhm-314 Change Name 💯

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

Many VHM-314 boards use "AC" series chips (e.g., AC20BP) which require proprietary SDKs to modify. Alternative Solutions for Device Identification Vhm-314 Change Name

Offers more customization and a dedicated data interface. Identify by MAC Address Every Bluetooth module has

Since software-based renaming is generally locked out for the average user, here are the best ways to manage multiple VHM-314 modules or customize your project experience. 1. Identify by MAC Address the VHM-314 uses a low-cost

Every Bluetooth module has a unique MAC address. If you have multiple "VHM-314" devices in one house, your phone or PC will usually list them as: VHM-314 (AA:BB:CC...) VHM-314 (DD:EE:FF...)

While the VHM-314 is a fantastic "plug-and-play" board for budget audio, its lack of name customization is its biggest drawback. If you need a unique identity for your Bluetooth signal, moving to a programmable module is the best path forward.

The board lacks a dedicated USB-to-UART interface for AT commands.
