Once connected, most smartphones (iOS and Android) allow you to within your Bluetooth settings. This doesn't change the broadcast name for other people, but it helps you keep track of which module is in the "Kitchen" versus the "Garage." 2. Hardware Swapping (The Pro Method)
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
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.
