I haven't tried it yet, but have you looked at this blog post (I //think// it is still relevant today)? https://corvid.io/2017/04/22/stupid-rfnoc-tricks-loopback/

Say I have a rfnoc graph that has been connected as Radio RX -> processing block -> Radio TX so there is no data samples streaming to/from the host. Can I just issue the "start streaming" command to the Radio block itself or do I need to use a uhd::rx_streamer to issue the command? Is there any other gotcha that I am overlooking? Thanks, Ryan -- Ryan L. Marlow R L Marlow Consulting LLC rlmarlow.com<http://rlmarlow.com>
