Vhm-314 Change Name Guide
Attach a SOIC8 test clip to the chip, or desolder the chip and place it into a CH341A programmer. Connect the programmer to your PC.
Open your device manager to determine which has been assigned to the adapter. Launch the JieLi Configuration Tool executable.
Open the saved hex file in a Hex Editor (such as HxD). Use the text search function to find the default string, "XY-BT" or "VHM-314."
Modifying low-cost development boards often comes with minor technical hurdles. Use this matrix to fix common failure modes: Probable Cause Corrective Action Swapped data lines or incorrect baud rate. Vhm-314 Change Name
If you lack the soldering equipment, programmers, or technical background required to execute the steps above, changing the firmware directly may not be viable. Consider these alternative workarounds:
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.
Most VHM-314 boards use a generic Chinese Bluetooth SoC (System on a Chip). To modify the internal firmware settings, you would typically need a USB-to-TTL Serial adapter (like a CP2102 or CH340) and specialized software like the OVC3860 Development Tool PSTool (for CSR chips) Complexity: Attach a SOIC8 test clip to the chip,
Go to Bluetooth settings, connect to the VHM-314, tap the settings icon next to the device, and select "Rename."
Inspect the VHM-314 PCB. Look for small, unpopulated copper pads labeled TX , RX , GND , and 5V (or VCC). On some ultra-compact revisions, these pins are not broken out to pads, meaning you must carefully solder wires directly to the physical pins of the SoC package (refer to the specific datasheet pinout for your chip model, such as the JL AC6925A).
Within the SDK configuration utility, navigate to the Bluetooth settings tab. Locate the field labeled "Local Name" or "Bluetooth Name". Change "VHM-314" to your desired custom name. Launch the JieLi Configuration Tool executable
The VHM-314 is a highly popular, low-cost Bluetooth audio receiver board used extensively by DIY electronics enthusiasts. It allows users to convert vintage amplifiers, wired headphones, or car stereos into wireless sound systems. However, a common frustration with this board is its default Bluetooth broadcast name, which usually appears as "XY-BT" or "VHM-314." When deploying multiple boards in a single household, identifying the correct device becomes difficult.
