[Discuss-gnuradio] How to swtich tx/rx of XCVR2450 when using gnuradio OFDM_benchmark example?

HI guys,

Thanks in advance.

Currently I have been engaged in a project which is based on the OFDM_benchmark example. I plan to realize a round trip communication between two USRP2 node. Concretely, I want to control the node A switch to RX mode after it finishes transmitting a packet. In such way, the node A can receive the ACK from the node B.

 I know  XCVR2450 does not support FULL DUPLEX. BTW, I wonder if XCVR2450 can handle the tx/rx switch job automatically? Or should I implement some script (Python) to control it?

Any help or instruction will be greatly appreciated.

Best,

Kay.
