IWR6843AOP: Guide to using the API code and Control Tool for controlling individual antennas

Part Number: IWR6843AOP

Tool/software:

Hi IWR6843AOP Champ !

A customer needs test code for individual antenna control for their IWR6843AOP based module for the product qualification process.
Is there an API code to control each TX/RX and is it possible to control each antenna in a radar tool such as mmWave Studio?
If it is not possible to control the antenna in the existing Radar tool, please guide me on how to enable/disable each antenna using UART command from the host MCU, etc.

Thanks.

Best Regards, 

Jack
