Hello, We will be running a basic flow graph to test our antenna with the LimeSDR. The flowgraph is basically an osmocom source--> WX GUI waterfall sink.
It will run perfectly fine for some operations and then every once in a while we will run it and get this error. It then works fine after we hit the reset button on the LimeSDR. We will get this error.
