[Discuss-gnuradio] TX/RX simultaneously using one USRP board

[Dawei Shen]

Hi, Eric and other friends

Now I am working on a project that requires simutaneous TX/RX within
one usrp board. I equip too FLEX400 daughter cards on one USRP board.
What I am trying to do is to use the TX to retransmit (i.e. relay)
what the USRP has received from the RX. Is it doable under the current
framework of GNU Radio? If so, could you provide any hints on how to
realize this? An obvious question to me is that in the Python code, we
should either define the usrp as a source or a sink, but in my
application, the USRP board serves as both sink and source. So what
should I do in my case?

Thank you for your input
