Save the modified binary file. Use the programming software to erase the external flash chip and write the new modified file onto it.
Method 1: The "Simple" Approach - Renaming in Your Phone/PC Settings
Method 1: Flashing the Chipset via JL-Programmer (The Official Hardware Approach)
: 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)
Critical Rule: The new name must usually be the exact same character length as the original name to avoid shifting the memory addresses, which would corrupt the firmware. If your new name is shorter, fill the remaining character slots with null bytes ( 00 in hex). Vhm-314 Change Name
While the is a popular and affordable Bluetooth audio receiver, it does not officially support simple "AT commands" (like some data modules do) for renaming. To change the broadcast name—typically "VHM-314" or "XY_BT" —you generally have two paths: a simple software-side alias or a complex hardware-level firmware modification. Option 1: Software Renaming (The Easy Way)
depends on the specific hardware version you have. While most generic versions are "read-only," higher-end models using specialized chips like those from Qualcomm (CSR) Jerry (JL) allow for firmware-level changes. Method 1: PC/Smartphone Alias (Easiest) This method changes how the device appears only on your specific phone or computer . It does not change the name for other people. Settings > Bluetooth , tap the gear/info icon next to the , and select the Edit/Pencil icon Settings > Bluetooth , tap the "i" icon, and select Control Panel > Devices and Printers , right-click the Properties , and look for a tab to rename it. Method 2: Hardware Programming (Advanced)
: Go to Settings > Bluetooth , tap the gear icon next to the connected VHM-314, and select "Rename" .
The quest to change the Bluetooth name of a VHM-314 module is a journey that ends where it begins: with a simple, practical solution that works on your phone or PC. While a permanent, device-level name change is currently out of reach for the average user due to the hardware's design, the local renaming workaround is so effective that it makes the underlying limitation a non-issue for almost any project. Save the modified binary file
Before attempting any hardware modifications, it is crucial to understand the chips powering the VHM-314. The board typically relies on one of two highly integrated Bluetooth audio SOCs (System on a Chip): (e.g., AC692X, AC695X) Asolid / Bluetrum chips
Some variants of these modules support AT commands if you connect a serial bridge (like an Arduino) to the TX/RX pins. AT+NAME[NewName] Response: The module should return OK if successful.

Tap the (settings icon) next to the "VHM-314" device name. Select Rename . Type in your new desired name and save. On iOS (iPhone/iPad) Connect your VHM-314 to your iPhone. Go to Settings > Bluetooth . Tap the blue "i" icon next to the VHM-314 device. Tap Name and change it. On Windows Connect the module to your PC. Open Control Panel > Devices and Printers . Right-click the VHM-314 device and select Properties . Go to the Bluetooth tab, type the new name, and click OK.
Connect the VHM-314 to your USB-to-TTL adapter using a cross-over configuration: VHM-314 TX →right arrow UART Adapter RX VHM-314 RX →right arrow UART Adapter TX VHM-314 GND →right arrow UART Adapter GND Right-click the device, go to Properties , and
The VHM-314 is a highly popular, budget-friendly Bluetooth 5.0 audio receiver module frequently used in DIY audio projects. While excellent for adding wireless capabilities to speakers and amplifiers, it often comes with a generic, non-descript Bluetooth name like "BT-Audio" or similar.
Before diving into the nomenclature shift, it is crucial to understand what Vhm-314 is and why it generated so much attention.
The name change is intended to [briefly explain the reason for the name change, e.g., "reflect a change in branding" or "align with updated regulatory requirements"].
