Is there any information about STM32 AOA UWB here?

I just found this board,it seems that the AOA function is realized by STM32. Our company’s products also want to do the same. Do you have any software and hardware information about this board

Interested to hear where you found it!
That is an old piece (now unsupported) of hardware which uses two DW1000 to achieve PDoA functionallity.

Thanks,I ported this version of the code to STM32F411. AOA TAG still uses STM32L151CCU6. It can now measure the distance normally but cannot obtain the angle normally. What should I pay attention to when transplanting AOA? I have read the official PDF Documentation
