Slew of errors upon running

[ofadam]

Sadly, I had everything working yesterday and now am stuck with these errors when accessing via browser. I appreciate any help you may be able to give.

looks like the soapy sdr driver check needs additional protection for when SoapySDR is not installed...

FileNotFoundError: [Errno 2] No such file or directory: 'SoapySDRUtil': 'SoapySDRUtil'

I can fix that, just give me a minute.

interesting though that it worked before.

[ofadam]

I think that I actually didn't have SoapySDR installed at first (I'm only using an RTL-SDR with it at this point), but installed the packages to see if it would fix a different problem I had. That may have triggered this!

[jketterl]

yeah it should still work without. if you're running a checkout, just do a git pull now, the commit i did should fix it.

[ofadam]

That did indeed fix the loop I was getting! Now I need to figure out why I'm getting an "usb_claim_interface error -6" when it tries to open the RTL-SDR...

[jketterl]

probably a leftover from the previous errors. try to kill all instances of csdr and rtl_connector. that's something that happens a lot when openwebrx gets interrupted, and i can't seem to handle this properly due to the piping.

[ofadam]

Killing those instances fixed it – thanks again for all your help. Now to work on the antenna setup for this little remote netbook!

Regarding that - consider using sessions or process groups to keep track of all spawned processes to kill them all when needed. Check https://docs.python.org/3/library/subprocess.html#popen-constructor and start_new_session.

[jketterl]

it's alreay using process groups for the pipelines... the problem arises when a single process of the pipeline dies. this usually causes some unpredictable behaviour.
