Different manufacturers and board revisions use different names. Common names include XY_BT , VHM-314 , and various generic identifiers.
You must identify the SPI (Serial Peripheral Interface) pins on the VHM-314 board—specifically SPI_CS, SPI_CLK, SPI_MISO, SPI_MOSI, and GND. These are often tiny pads on the PCB.
Locate the field labeled "BT Name" , "Local Name" , or "Device Name" . Delete the default string and type your new custom name (e.g., "Living Room Speaker"). Keep the name under 20 alphanumeric characters to ensure stability.
A (CH340G, FT232RL, or CP2102). A soldering iron and fine hookup wire. A Windows PC. Vhm-314 Change Name
Unlike a simple UI display change, a "Name Change" at the VHM-314 level implies an update to the system's core reference for an object, user, or node.
Burn the modified hex file back onto the EEPROM chip. Re-solder the chip to the VHM-314 if it was removed.
To change the broadcast name permanently (so it shows up as "My Custom Speaker" for everyone), you must use hardware tools. The VHM-314 typically uses an (like the AC208 or AC1847). These are often tiny pads on the PCB
In the world of DIY electronics and audio projects, the VHM-314 Bluetooth audio receiver module has carved out a reputation as an affordable workhorse. For around $2–5, you can add wireless streaming capabilities to nearly any powered speaker system, amplifier, or vintage radio. But there is a question that surfaces again and again across forums, project logs, and maker communities: This article dives deep into that question, exploring why the module’s identity matters, what names it actually shows up under, and the surprisingly complex reality of renaming these tiny devices.
While specific code definitions vary across proprietary systems, typically refers to a Validation Handling Module or Virtual Host Management protocol. The "Change Name" operation associated with it is rarely as simple as renaming a file; it usually involves altering a primary key or a unique identifier within a database architecture.
Please update any records, documents, or references to reflect this change. Keep the name under 20 alphanumeric characters to
Do not change the overall file size of the .bin image. If your new name is shorter than "VHM-314" (7 characters), fill the remaining empty character slots with null bytes ( 00 in hex). If your new name is longer, ensure you do not overwrite critical adjacent code bytes, or the board will crash.
