Re: Output Issue in example_corr_est_and_clock_sync.grc

Hi Mubashira,

I have created https://github.com/gnuradio/gnuradio/issues/5528 (Some gr-digital/examples/packet do not produce expected tags) to address your problem. I think that if you change the trigger to 'Auto' on those two QT GUI Time Sinks, you will see the data (but no tags).

You can track the progress on that issue by clicking the link above.

The decision to "backport" a fix to older versions is made by the maintainers. However, note that version 3.7 is no longer being maintained.

Be safe,

Hi Barry,

I was actually following the Packet Communications tutorial, when I came across those example flowgraphs.

Are the older GNU Radio actually being worked on now? Or are the bugs/issues in them just being fixed in the more recent versions?

Hi Mubashira,

When I was writing the https://wiki.gnuradio.org/index.php?title=Packet_Communications tutorial, I remember having some problems with the gr-digital/packet examples. If you haven't already done so, you might like to look at that tutorial.

I don't have my GR 3.8 computer up right now, but when I get back to it, I will look into those examples again.

Best wishes,

Hi,

I am trying to run this flowgraph in gr-digital/packet examples on GNU Radio 3.8. When I run the flowgraph, the output shows a flat line (amplitude is a constant zero).

I do not have enough understanding of these blocks yet to determine what is the problem here.

Can anyone please mention how the output can be corrected?
