Is it possible to operate in 1R1T mode with RX2A and TX2B using the No OS Drivers?

Hi!

We are running into issues trying to select RX2A and TX2B to operate in 1R1T mode. It seems the AD9361 defaults to operate in MIMO mode when we configure it to select RX2A and TX2B. Currently, our design uses the latest no OS drivers. Is 1R1T not possible with our desired RF configuration?  

Thank you and Kind Regards.

    HI  
    

    

    

    RX and TX to belong to the same RF channel. When operating in 1T1R mode it selects Tx1A and Rx1A pair or Tx1B and Rx1B pair in the internal based on A and B side selection. If you select one Tx/Rx port with A and Tx/Rx port with B it will lead to MIMO.
    

    

    Please select the same side during initialization to avoid this confusion.
    

    

    Regards,
    

    SJ
