I wanted to let everyone know that VHM-314 will now be referred to as [New Name]. This change is effective [Date] and is part of our ongoing efforts to [briefly mention the reason or context if needed].
"Database/Inventory Update Request:
The board lacks a dedicated USB-to-UART interface for AT commands.
Since "Vhm-314" appears to be a technical ticket, issue ID, or a specific task identifier (likely from a software development or IT support context), I have structured this as a . Vhm-314 Change Name
This method is perfect for 99% of users. It instantly solves the identification problem.
The firmware is typically stored on a chip that is not user-programmable without specialized hardware (like an ICSP programmer).
Go to Settings > Bluetooth , tap the "i" icon next to the device, and select Name . I wanted to let everyone know that VHM-314
Look for Bluetooth modules explicitly labeled with "AT Command Support" or those using the Qualcomm CSR8645 / CSR8675 chips.
Inspect your VHM-314 board closely. Look for tiny unpopulated copper pads labeled TX , RX , GND , and 5V (or VCC).
Changing the broadcast name allows you to personalize your audio hardware and prevent connection confusion. Because the VHM-314 relies on a cost-optimized, fixed-function audio SoC (often from the JieLi AC69xx family), modifying its firmware requires specific technical approaches. Since "Vhm-314" appears to be a technical ticket,
Type over the old name with your new custom name.
Unlike consumer Bluetooth speakers that offer a smartphone app for customisation, the VHM‑314 is a bare‑circuit‑board OEM component. There is no app, no web interface, and no driver software that lets you tweak settings after the board is powered on.
Search for the parameter local_device_name or name in the PS Key list.
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).
When attempting firmware or physical modifications on low-cost audio hardware like the VHM-314, keep these factors in mind:
