Hi, Please go through the tutorial [1].
Short version, 1. Use one 5in-1out selector block 2. Use on "Function Probe" block 3. Set the "Poll Rate" based on your delay 4. Generate python file using "Generate flowgraph" button 5. Set your selector's input index in the function probe Sample function probe >>def _fn_probe_probe(): >> while True: >> try: >> self.blks2_selector_0.set_input_index(random.randint(0,4)) >> except AttributeError: >> pass >> time.sleep(1.0 / (0.3)) 6.Run your python code [1] https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GNU_Radio_in_Python#315-Modifying-the-GRC-Generated-Python-File Sreeraj On Sun, Dec 7, 2014 at 10:59 PM, Vitt Benv <vitt...@gmail.com> wrote: > Hi everybody, > I need to "switch" randomly 5 different signal generator via selector > block every [say] 3 seconds.... > > So , in GRC, I've a vector_source with values coming from > [random.randint(0, 4) for p in range(0,4)].
