The Jieli BR21 is a Bluetooth-based chip often found in USB dongles, soundboards, and inexpensive audio receivers. Because Jieli (Zhuhai Jieli Technology) primarily manufactures integrated circuit (IC) solutions for other brands, there isn't a single "official" driver; instead, the device typically relies on generic Windows/macOS/Linux drivers or specialized update tools provided by the product manufacturer. Common Driver Behavior Plug-and-Play: Most Jieli BR21
devices are designed to be "driverless" and should automatically be recognized by Windows 10/11 as a USB Audio Device or a Bluetooth Dongle.
Storage Mode Conflict: Users often report these devices appearing as a "Storage Device" or "CD Drive" instead of a Bluetooth adapter. This is sometimes a manufacturer-implemented "virtual drive" containing a basic driver installer.
Identifier Scans: If your system fails to recognize it, third-party repositories like DriverIdentifier list versions for specific OEM implementations, such as the Borofone BR21 or Teclast variants. Firmware & Tools
If the device is malfunctioning, you may need technical tools rather than a standard driver:
Update Tools: Manufacturers like Axtek provide manual update tools for Jieli-based dongles to force firmware upgrades or change operating modes.
SDKs for Developers: For advanced users or developers, Jieli's official GitHub hosts SDKs and bootloaders for their various series (AC63, AC69, etc.), which power BR21-class hardware. Troubleshooting Tips
Check Device Manager: Look under "Sound, video and game controllers" for " JieLi BR21 " or "USB Audio Device."
Toggle Modes: If the device has a physical button, holding it while plugging it in may switch it from "Storage" mode to "Bluetooth/Audio" mode.
Manufacturer Website: Look for the specific brand of your hardware (e.g., Borofone, Teclast, or generic "Bluetooth 5.0") rather than searching for "Jieli," as Jieli is only the chip maker.

While there is no official "blog post" from the manufacturer, users often encounter the Jieli BR21
(or related Jieli chips like the BR17) as a confusing device that appears as a "Storage Device" or "CD Drive" when first plugged into a computer.
Below is a detailed guide structured as a technical blog post to help you understand what the Jieli BR21 is and how to get it working. Solving the Mystery of the Jieli BR21 Bluetooth Driver
If you’ve recently bought a cheap USB Bluetooth adapter or a DIY audio module, you might have noticed it shows up in your device manager as "Jieli BR21"
—but instead of working as a Bluetooth dongle, it appears as a mass storage device or a virtual CD-ROM.
This is a common headache for users, but the "driver" issue is usually a misunderstanding of how the hardware functions. What is the Jieli BR21?
Contrary to popular belief, the Jieli BR21 is often not a standard Bluetooth "stick" for connecting mice or keyboards. Instead, most of these devices are Bluetooth audio receivers designed specifically for sound. The "Storage Device" Trap:
When you plug it in, the computer sees a small partition. This is often where the manufacturer stores default configuration files or even the "manual." The Chipset:
Jieli (JieLi Technology) is a massive producer of low-cost Bluetooth chips (like the AC690X series) found in everything from $5 speakers to car FM transmitters. Why Can't I Find a Driver?
You usually won't find a "Jieli BR21 Driver.exe" because the device is designed to be Plug-and-Play (PnP) using standard Windows/Linux USB Audio and HID drivers. If it isn't working, it's likely for one of these reasons: Audio-Only Mode:
Many BR21 adapters are hardcoded to act as a "USB Sound Card." They receive Bluetooth audio from your phone and pipe it into the computer as a microphone input. They cannot "search" for other Bluetooth devices from your PC. Missing "Mode" Switch:
Some models require you to press a button (if available) or double-tap a switch to move from "Receiver" mode to "Transmitter" mode. Firmware Security:
For advanced users trying to reflash these chips, Jieli uses security keys (e.g., br21loader.bin
) that prevent unauthorized firmware from being loaded, making custom drivers nearly impossible to build. How to Get it Working
If your Jieli BR21 is showing up as a drive and not a radio, try these steps: Check Sound Settings: Go to your Sound Control Panel
(Input/Recording tab). Look for a device named "USB Audio Device" or "Jieli." If it's there, your PC thinks it’s a microphone. The "Eject" Trick:
Some devices stay in "Storage Mode" until you right-click the virtual CD drive in "This PC" and select
. This can sometimes trigger the device to switch to its Bluetooth or Audio function. Update via Windows Update:
Instead of searching for "Jieli" drivers, run a standard Windows Update with the device plugged in. Windows will usually pull the generic "Bluetooth Radio" or "USB Audio Class" driver automatically.
If you bought the BR21 expecting to connect a Bluetooth controller or headset to your PC, and it's showing up as a storage device, you likely have an Audio-only receiver
. For full Bluetooth functionality (mice, keyboards, file transfer), you may need a dongle with a chipset instead. Do you have the hardware ID At its core, the BR21 is a Bluetooth
