DOA of Respeaker 4-mic Array v2.0

Hi

It’s about the Respeaker 4-mic Array v2.0 .
I just have tested DOA.py on window 10
(https://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/#tech-support)

could I get DOA value using c/c++ DLL?
or
Is it possible to communicate with Respeaker 4-mic Array v2.0 using Serial-COM port(UART)?

I wanna control Respeaker 4-mic Array v2.0 . directly without python tuning.py module.

please check this. thanks
