Once you have downloaded the jieli_br21_driver_free.zip file, follow these steps to install it correctly.
Microsoft sometimes certifies Jieli drivers.
Linux uses the open-source snd-usb-audio driver. It works fine, but you will need pulseaudio or pipewire to tweak codecs. The Windows ".inf" file is useless on Linux.
Many "Bluetooth dongles" with this chip are actually recognized as audio devices rather than standard Bluetooth adapters. If this is the case, look for it under "Sound, video and game controllers" in Device Manager .
The BR21 uses the 2.4 GHz band. If you have active Wi-Fi, a microwave, or many other Bluetooth devices nearby, you may experience disconnections. This is a hardware limitation, not a driver issue.
: If the driver fails to start, try right-clicking it in Device Manager , selecting "Uninstall device," and then unplugging/replugging the device to force a fresh install of the generic Windows driver.
