Re: how to auto detect peak frequency in QT FFT sink

[Cinaed Simson]

I was just curious - and the only reason I choose FFT peak was because you did.

I built gnuradio and the OOT modules from source. And it doesn't matter where you hang the gnuradio root.

And it's highly unlikely that I could compile, link to gnuradio, and run make test with missing dependencies.

On the machine I first tested it which was an old 64 bit Dell Optiplex desktop running Debian 10 (buster), and it logs the following error in dmesg:

  [1233081.177466] traps: python3[22326] trap invalid opcode ip:7feef013fc5c sp:7ffed724b720 error:0 in libgnuradio-fhss_utils.so.42c85270[7feef0133000+1d000]

- where I believe error:0 implies division by zero.

Then I installed it on a new i5 laptop and it passes the first test - which I presume is the division by 0 error above - but fails the other 2 tests - and doesn't log any errors in dmesg.

Then I downloaded and installed gr-pdu_utils and gr-sandia_utils and both of those packages are riddled with make test errors.

I'm presuming these are work in progress - and I don't the time right now to explore those errors further.

this might depend on how you install it

I see you are using and /opt/ prefix. I just install it with `pybombs install gr-fhss_utils` and it works.

Maybe you are missing a dependency?

FYI the FFT peak block you want is a simple hier block you could make without installing anything. Look at this file.

Hi Kyle - after I build gr-fhss_utils and run the tests, all 3 tests fail.

Do the tests work?

I did a pull but it was up to date.

I'm running gnuradio 3.8.2.0 on Debian 10 or buster.
