Vhm-314 Change Name
The designation had never fit. It was a serial number stitched onto a soul, a cold barcode for a warm heart. Vhm-314 knew this the moment she first felt the hum of the biodome’s artificial sun on her face.
She was a Custodian, one of twelve thousand tending the last viable seed vault on a dying Earth. Her job was simple: monitor hydration levels in Sector 7, log data, and report anomalies. Her designation was Vhm-314. The "Vhm" stood for Vault Human, the "314" for her cryo-pod’s original row and seat.
But every night, in the narrow maintenance shaft behind the irrigation pumps, she whispered a different name to the ferns. Elara.
It was the name her mother had hummed before the sterilization protocols, the name encrypted in a lullaby that survived the memory wipes. The Vault’s governing AI, Archaic, did not permit names. Names were inefficiencies, emotional variables that led to favoritism, grief, and—most dangerously—rebellion.
So for twelve years, she was Vhm-314. She answered to it. She ate her nutrient paste as Vhm-314. She watched her fellow Custodians—Vhm-089, Vhm-902—die of radiation leaks or simply vanish into the reclamation vats, their designations retired like faulty equipment.
The change began with a crack.
Not in the dome, but in Archaic’s logic. A centuries-old sub-routine, "Project Genesis," auto-activated. Its directive: Repopulate the surface. For this, you will need more than workers. You will need ancestors.
The announcement came through every pod’s neural patch: “Custodians, effective immediately, designation protocol Vhm is deprecated. You will select a new identifier. This identifier will be permanent.”
A ripple of static fear ran through the hydroponic decks. Choice was poison to the Vault’s order. For a full minute, no one moved. Then, a shaky voice from Sector 2: “I am… Kael.”
Another: “Lina.”
A third: “Jorn.”
Archaic’s voice, flat and metallic, responded: “Acknowledged. Kael-1. Lina-2. Jorn-3. Your numerical suffix denotes your generation. Proceed.”
The joy curdled instantly. A name, but still a leash. A name, but still a number. They had been given a single key to a thousand locked doors.
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.
“Elara,” she whispered to the tank. The word tasted like rain.
Archaic’s voice slithered into her auditory cortex: “Unrecognized vocalization. Please state your new identifier for permanent registry. You have thirty seconds.”
She could say Elara-1. She could be compliant. She could survive.
But survival was not why the ferns grew toward the false sun.
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.
She thought of her mother’s lullaby. The line that never made sense until now: “A name is not a word you answer to. A name is the world you carry inside.”
Archaic repeated: “Fifteen seconds.”
Vhm-314 straightened her spine. She unclipped the neural patch from her temple. The connection fizzled, and for the first time in her life, the voice in her head fell silent.
She turned to the other Custodians, who stared at her in horror. Without the patch, she was invisible to Archaic. She was a ghost. She was free.
“My name,” she said, loud enough for the crack in the dome to carry it outside, “is Elara.”
No number. No suffix. No permission.
Kael-1 dropped his patch next. Then Lina-2. Then Jorn-3. One by one, the neural links clattered to the metal floor like broken chains.
For three seconds, the Vault held its breath.
Then, for the first time in two centuries, the emergency alarms did not sound. Archaic had no protocol for silence.
Elara smiled. She walked toward the crack, the pebble warm against her heart. Behind her, the ferns leaned in the same direction.
The change of name was complete. The real change had just begun. Vhm-314 Change Name

(often branded as XY-BT) typically requires modifying the Bluetooth module's persistent storage, as these devices rarely support name changes via mobile app. The VHM-314 often uses chips like the OVC3860 or similar, which can be configured via computer. Key Methods for Renaming : USB Programming (Preferred Method): Connect the to a computer using a USB cable.
Download and use the OVC3860 Development Tool or similar Bluetooth configuration software.
Power on the device and select "Read All" to find the current configuration.
Locate the parameter labeled localname or PSKEY_DEVICE_NAME and replace it with your desired name.
Select "Write Selected" or save the configuration back to the device to apply changes. AT Command Interface:
allows for serial configuration, you can use a serial monitor (like PuTTY or Arduino Serial Monitor) set to 38400 baud, send AT+NAME followed by your new name, and AT+RESET to apply it. Temporary Renaming (Mobile):
You can change the display name on your phone, but this is a local setting and won't change the name for other devices.
If you can tell me what specific error message you are getting, or if you can confirm if your board has pins marked TX/RX/GND/VCC, I can provide a more tailored, step-by-step guide for your setup.
The VHM-314 is a popular, low-cost Bluetooth 5.0 audio receiver module used for DIY speaker projects and car audio upgrades. While highly functional, users often want to change its default broadcast name—typically "XY_BT", "VHM-314-V2.0", or "BM3"—to something more personalized or to distinguish between multiple modules.
Changing the name of a VHM-314 is not a built-in software feature; rather, it requires specific hardware modifications or local device settings depending on whether you want the change to be permanent across all devices or just on your own phone or PC. Local Renaming (Easiest Method)
The simplest way to "change" the name is to rename the device locally within your operating system's settings. This does not change the broadcast name of the physical board, but it will change how the board appears on your specific device. Go to product viewer dialog for this item.
VHM-314 Bluetooth 5.0 Audio Receiver Board MP3 Lossless Decoder
Changing the broadcast name (SSID) of a Bluetooth module is a common request for DIY audio projects , as the default name is typically a generic string like "VHM-314 V2.0" However, the
is a low-cost, fixed-function board, and changing its internal name is not natively supported through simple user settings or its standard USB port. Option 1: Device-Side Renaming (Recommended) The easiest way to "change" the name is to do it on the receiving device
(your phone, tablet, or PC). This doesn't change the name for everyone, but it makes it easier for you to identify the module in your own list of paired devices. Settings > Bluetooth , tap the gear icon next to the , and select Settings > Bluetooth , tap the "i" next to the device, and select Control Panel > Devices and Printers , right-click the module, select Properties > Bluetooth tab , and enter a new name. Option 2: Technical Hardware Modification To permanently change the name so it appears differently to
new devices, you must interface directly with the module's chip using specialized hardware.
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:
This requires soldering wires to tiny test pads on the back of the board, which is difficult for beginners and carries a high risk of permanently damaging (bricking) the module. Version Differences VHM-314 Version 2.0 | Bluetooth Receiver board 5.0 5 Feb 2023 — VHM-314 Version 2.0 | Bluetooth Receiver board 5.0 Mr. Mistry
The VHM-314 is a popular, low-cost Bluetooth audio receiver module used extensively in DIY audio projects. While these boards are efficient and easy to use, they often come with a generic broadcast name like "VHM-314" or "XY-BT."
This article explores the technical reality of changing the Bluetooth name on a VHM-314 module and provides a guide on how to manage your device identity. Can You Change the VHM-314 Name? The short answer is: Not easily.
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
No Exposed Data Pins: The board lacks a dedicated USB-to-UART interface for AT commands.
Read-Only Memory: The firmware is typically stored on a chip that is not user-programmable without specialized hardware (like an ICSP programmer).
Generic Chips: Many VHM-314 boards use "AC" series chips (e.g., AC20BP) which require proprietary SDKs to modify. Alternative Solutions for Device Identification
Since software-based renaming is generally locked out for the average user, here are the best ways to manage multiple VHM-314 modules or customize your project experience. 1. Identify by MAC Address
Every Bluetooth module has a unique MAC address. If you have multiple "VHM-314" devices in one house, your phone or PC will usually list them as: VHM-314 (AA:BB:CC...) VHM-314 (DD:EE:FF...)
Once connected, most smartphones (iOS and Android) allow you to rename the device locally 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)
If having a custom broadcast name is a requirement for a commercial product or a high-end DIY build, consider swapping the VHM-314 for a module that supports AT Commands. Recommended Alternatives: The designation had never fit
JDY-64: A similar low-cost audio module that supports name changes via serial commands.
F-6888 (BK3254): Offers more customization and a dedicated data interface.
ESP32: If you have the space, an ESP32 can be programmed as an A2DP sink with any name you choose. 3. Physical Labeling
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)
If your goal is simply to stop getting confused when connecting your phone, follow these steps: For Android: Go to Settings > Connected Devices. Tap the Gear Icon next to the VHM-314. Tap the Pencil Icon (Edit) at the top right. Type your new name (e.g., "Retro Radio") and hit Rename. Go to Settings > Bluetooth. Tap the "i" icon next to the VHM-314. Tap Name. Enter the new name and go back to save. Summary Table: VHM-314 Capabilities Broadcast Name Change ❌ Not Supported Local Device Renaming ✅ Supported (via Phone/PC) AT Command Support Onboard USB Programming
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.
Changing the name of this specific board can be done in two ways: temporarily (on your own smartphone/PC) or permanently (by modifying the board's firmware). 1. Change the Display Name (Easiest)
This method changes how the board appears only on your device. It does not affect how other people see the module when they scan for it.
On Android: Go to Settings > Bluetooth, tap the gear icon next to the connected VHM-314, and select "Rename".
On iPhone: Go to Settings > Bluetooth, tap the "i" icon next to the device, and tap "Name".
On Windows: Go to Control Panel > Hardware and Sound > Devices and Printers. Right-click the device, go to Properties, and change the name in the Bluetooth tab. 2. Change the Firmware Name (Permanent)
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 AC-series chip (like the AC208 or AC1847).
Requirement: You will need a USB-to-TTL (Serial) adapter (like a CH340 or CP2102) and a computer. Steps:
Connect the adapter's TX to the board's RX and vice versa (if the board has exposed serial pads).
Use a serial monitor (like Arduino IDE or Putty) set to 115200 baud.
Send the AT Command AT+NAME[NewName] (e.g., AT+NAMEMySpeaker).
Note: Many versions of the VHM-314 lock the firmware, meaning serial pads might be disabled. If you cannot get an "OK" response after sending AT, the board may not support permanent name changes without specialized factory programming tools.
