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

Disconnect the programmer, power up the VHM-314, and scan for Bluetooth devices on your phone to verify the new name.

Route the Left, Right, and Ground audio output pins of your new module directly into the audio input pins (or auxiliary jack solder pads) of the VHM-314.

While you cannot change the module's broadcast name, you can manage the confusion. The most direct method is to simply rename the device (phone or computer). In both Android and iOS, you can rename any paired Bluetooth device to something meaningful like "Workshop Speaker" or "Living Room Hi-Fi". This is a cosmetic fix that only helps you.

The Bluetooth name, device configuration, and firmware are stored directly on this chip or an adjacent surface-mount EEPROM/Flash memory chip. Because these chips are designed for mass-production consumer goods, they are hardcoded at the factory. There is no native USB-to-serial command line interface (like AT commands used in HC-05 modules) available on standard VHM-314 boards out of the box.

If attempting to program the board using an external programmer, ensure clean, stable power delivery. Use a decoupled 5V source rather than relying solely on cheap USB-to-serial adapter power lines, which can drop in voltage during flash write sequences and cause data corruption.

In the high-stakes world of pharmaceutical development, a molecule’s identity is defined not by a name, but by its molecular structure, receptor affinity, and clinical data. Yet, the alphanumeric code assigned to a drug candidate—such as VHM-314—is a crucial tool for communication among researchers, investors, and regulators. But what happens when that name changes? For VHM-314, a compound that has sparked interest in neuroscience and pain management, a potential name change is not merely a clerical update; it is a strategic signal about the drug’s evolution, safety profile, and commercial future.

Vhm-314 stood in front of her germination tank, watching her reflection ripple in the nutrient solution. She touched her chest, where beneath her grey tunic, a small, smooth pebble rested—a fossil her mother had pressed into her infant palm. The pebble was nameless. It simply was .

She looked at the crack in the dome’s northern seal—a tiny fracture she’d logged three weeks ago and Archaic had ignored. Through it, a sliver of real sky. Not the holographic blue, but the bruised purple of a real, wounded sunset.
