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.

I believe that the OFDM tunnel example automatically switches the TX/RX
port to receive when packets are not being transmitted so this should be
compatible with your XCVR2450 without modification.
