Hi all. I am into making DIY bluetooth seakers, so naturally have been getting various bluetooth or bluetooth enabled boards from aliexpress. I recently found the board that satisfies my every need, BT-201 (and BT-301). It has bluetooth audio channel, data channel, USB and TF card playback. BT-301 has line in and even FM radio. Both have huge AT command set to be used via serial port.
The boards could be flushed with newer firmware easily, that comes in updata.bfu file. The latest virsion I have intalled on the board when purchased is VER2.3-20200927 but I dont know where I can find the download.
Would anyone know where can I get latest documentation .zip (usually contains firmware file in it as well)? I have VER2.3-20191115 file, but it is quite a bit older.

Hello Sir,
I am using that module for a kind of bluetooth speaker that we designed. And we have issue about sound quality over 85%. It's started to cracking after 85%. Can we put a limit the sound level through AT commands (maybe custom firmware ?) or is there any way to fix that issue? Can you help me about this? Thank you.
