rx_fm using SoapySDR with Airspy mini won't terminate about soapyairspy HOT 3 OPEN

Its probably stuck in deactivateStream https://github.com/pothosware/SoapyAirspy/blob/master/Streaming.cpp#L205 If I had to guess, but it would be good to start with rx_fm and see which functions get called.

Can you add some strategic prints and see what function its stuck in? Is it a SoapySDR routine, and if so, is it some underlying airspy call like airspy_stop_rx or something like an infinite for loop in SoapyAirspy

from soapyairspy.

While I understand what you mean (add strategic code to write stuff to a log, so you can see where it gets stuck), I must say I'm not a programmer. But it's never to late to learn, so I will try to do a pull request and work with that.

This is the section of code in rx_fm that I believe closes the stream:

        SoapySDRDevice_deactivateStream(dongle.dev, dongle.stream, 0, 0);
	pthread_join(dongle.thread, NULL);
	safe_cond_signal(&demod.ready, &demod.ready_m);
	pthread_join(demod.thread, NULL);
	safe_cond_signal(&output.ready, &output.ready_m);
	pthread_join(output.thread, NULL);
	safe_cond_signal(&controller.hop, &controller.hop_m);
	pthread_join(controller.thread, NULL);

	//dongle_cleanup(&dongle);
	demod_cleanup(&demod);
	output_cleanup(&output);
	controller_cleanup(&controller);

	if (output.file != stdout) {
		fclose(output.file);}

	SoapySDRDevice_closeStream(dongle.dev, dongle.stream);
	SoapySDRDevice_unmake(dongle.dev);
	return EXIT_SUCCESS;

So do you believe I should focus on rx_fm instead?

Thats perfect, its an onion and you have to work your way into the center starting from the outside

Which one of these calls get stuck? That will tell us where to look next.

I dont have an airspy to validate this, but I can do my best to offer suggestions
