When using GNURadio Companion, they only appear when closing the flowgraph. On my application, which uses the same gnuradio code directly in c++ multiple times ( creates a usrp, then a flowgraph that uses it, stops the flowgraph, then starts another after a few seconds) I see the errors at the end of the first, then during streaming on all subsequent flowgraphs.
Occasionally I am getting a IOError: no response packet AssertionError when I start streaming (typically after a couple of other stream instances) and it causes my entire application to hang. ----------------------------- Jacob Knoles On Mon, Jul 9, 2018 at 10:53 AM Marcus D.
