Actually, I have referred your "wl_example_basic_txrx" code given in your EXAMPLE TAB of this portal and in the comment you have taken both board are 2RF only. But I have one 2RF Board and 4RF Board.

I have made some changes in such a way that RF_A and RF_B of 4RF Board will transmit signal and RF_C port of that board will act like Receiver.

But, it is saying "Invalid Interface Selection" every time. Please go through the above errors I have shown by Arrows.
