Finding a specific "JieLi BR21 driver link" is often complicated because is a chipset manufacturer that provides chips to third-party brands rather than a consumer hardware company that hosts direct driver downloads. Direct Driver Sources jieli br21 driver link
If you are looking for an executable to change the Bluetooth name or force a firmware update, several third-party driver aggregation sites host files. These are and should be used with extreme caution:
When you plug a BR21-based device into a computer, the system often recognizes it not as a Bluetooth adapter, but as a because the device uses a "Driver on Device" approach [13†L18-L21]. Essentially, the drivers are stored on a tiny internal flash drive partition of the dongle itself to make installation easy without needing an extra CD [13†L18-L21].

Because some generic Jieli BR21 drivers lack an official digital signature from Microsoft, Windows 10 and Windows 11 may block the installation.
If using Linux, the device might need to be switched from storage mode to audio mode using usb_modeswitch . This link or copies made by others cannot be deleted
: There isn't a single official "consumer" download link because the chip uses standard HID (Human Interface Device) Audio Class drivers already built into modern operating systems. Common Fixes for the "BR21" Error If your device is stuck appearing as "BR21" and won't work:
