Why this is interesting:
The BR21 itself isn’t a standalone “driver” you install on a PC for everyday use — it’s a Bluetooth audio SoC inside earbuds, speakers, or audio receivers.
But if you’re a developer or hobbyist wanting to flash custom firmware, update Bluetooth name/prompts, or debug the chip over USB (via the device’s hidden USB port), you need this Jieli USB driver. It allows tools like Jieli Developer Suite or Flasher Tool to communicate with the chip.

⚠️ Note for normal users:

If your PC says “BR21 driver missing” when plugging in a Bluetooth dongle or headset via USB, this driver is NOT for that.
For everyday Bluetooth headsets/speakers (BR21 inside), no driver is needed — they work via standard Bluetooth or USB audio class.
This driver is for engineering use only (flashing, debugging).

Alternative link (if the above is dead):
Search “Jieli USB driver AC692” on GitHub — many open-source projects for Jieli chips include the driver package.

Troubleshooting Your JieLi BR21 Bluetooth Connection If you've just plugged in a JieLi BR21

device and found it's not working as expected, you’re not alone. Many users find that Windows or Linux identifies these devices as a "USB Composite Device" or even a storage drive rather than a standard Bluetooth dongle.

Here is everything you need to know about the "drivers" and how to get your device running. 1. Understanding the JieLi BR21 The most important thing to know is that the JieLi BR21

The "Hidden" Bluetooth: Instead of adding Bluetooth to your PC, the chip inside typically receives audio streams from a phone or PC and plays them back.

Driver" installer from the manufacturer because the chip is sold to many different third-party brands like Borofone. If your PC doesn't recognize it automatically:

Check Device Manager: Look for a "USB Composite Device" or an "Audio Device" with a name like Jieli Technology.

Auto-Update: You can try right-clicking the device in Device Manager and selecting Update driver > Search automatically for drivers to let Windows find the best generic match.

Avoid Third-Party "Scanners": You may see sites like DriverIdentifier listing specific files for " Borofone BR21 JieLi BR17

," but these are usually just repositories of generic Windows system drivers. 3. Quick Fixes for Common Problems

The Blue LED Flash: Once the device is recognized, look for a flashing blue LED. This indicates it is in pairing mode. It may take a minute for the OS to finalize the setup before this starts.

No Bluetooth Icon? If you are looking for the Windows Bluetooth settings menu but it isn't appearing, your device is likely being treated as a sound card. Check your Sound Settings (Playback devices) to see if "JieLi Audio" or similar is listed there.

Firmware Tools: For advanced users or developers, technical manuals for Jieli USB Update Tools exist, but these are for flashing the chip's firmware, not standard consumer use. Are you trying to use the
