Hi all,

I have a question regarding a RFNoC loopback in plain UHD.

I am familiar with [1] and I have a working solution with gr-ettus and python. The problem is, I can not figure out how to connect the blocks in plain UHD. Does anyone have a working example in UHD for a RFNoC loopback?

Connecting in UHD/c++ fails with following error: "Error: RuntimeError: On node 0/Radio_0, output port 0 is already connected."...

Any help is highly appreciated :)

Daniel
