I connect my LimeSDR XTRX with my ubuntu system, then the LimeNGGUI FFT view works but if i click Capture enable, the program ask me to save the file into a directory, but after that there is nothing saved. No file has been saved.
It’s a bug, the samples are captured into a buffer, but the buffer is not written to file. Created bugreport FFT viewer don't save captured samples buffers to file · Issue #126 · myriadrf/LimeSuiteNG · GitHub
