CC2640R2F: Using a different antenna array instead of BOOSTXL-AOA

Part Number: CC2640R2F


Hi  , 

I am running an  aoa_sender and aoa_receiver application from 2.30 SDK on CC2640R2F with their BOOSTXL-AoA and I did a turntable test and looks ok to me  (the latest 3.20 doesn't seems to have these examples , instead have rtls_passive ,rtls_slave ,rtls_agent )

Now, I would like to use a custom antenna array with this development kit and run through the same examples. Did anyone try doing this? If yes, how did you connect your custom antenna array to the dev kit?

I understand that the 4 GPIOs control the antennas and array. There seems to be a switch that takes inputs from GPIO27,28,29,30 and selects the array and antennas and the RF path is connected 

Can anyone or TI rep help me in that?
