Vhm-314 - Change Name ((new))

Build the project within the IDE to generate a new firmware binary file.

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.

(less common, but present in certain revisions)

Inspect the underside or periphery of your VHM-314 board. Look for unpopulated copper solder pads labeled , RX , GND , and 5V (or VCC). If these labels are missing, you must locate the datasheet for the specific JieLi chip revision on your board to identify the UART debugging pins directly on the chip legs. 2. Wire the Interface Vhm-314 Change Name

, which offers full software control over the Bluetooth broadcast name. wiring diagram

Most VHM-314 boards utilize JieLi (JL) microchips. JieLi provides proprietary software tools for developers to configure their chips via a PC. This is the cleanest method to change the Bluetooth ID without physically altering the board layout. Prerequisites and Tools Needed A Windows-based PC.

The straightforward answer is .

True modification of the VHM-314 broadcast name requires modifying the onboard ROM or EEPROM memory of the master system-on-chip (SoC). This module typically utilizes a .

Disconnect the clip and power the VHM-314 board normally to confirm the name change. Troubleshooting Common Connection Issues

Stick to basic alphanumeric characters (A–Z, 0–9) and avoid symbols or spaces when naming your device via AT commands or firmware files. Special characters can cause parsing errors in the underlying Bluetooth stack code, resulting in boot loops or a complete failure to advertise the Bluetooth beacon.
