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
It sounds simple, but for DIY enthusiasts building multi-room audio, physical labeling is the most effective tool. Use a label maker to put the unique ID or the local name you assigned on the outside of the project box. How to Rename VHM-314 on Your Phone (Local Only)
