If you are hunting for an "exclusive" driver for the Jieli BR21, There is no magic software repository maintained by Jieli for end-users.
Developing on proprietary silicon can be challenging due to the lack of community forums like StackOverflow for debugging. If you are experiencing stability issues, system crashes, or audio distortion on a BR21-based design, implement these troubleshooting protocols: Jieli chips typically use naming conventions like AC69xx,
required to interface with the chip's internal 32-bit DSP and Bluetooth stack. Technical Overview: AC692N (BR21)
