Hangs when receiving signal #2171
Comments
Did you set up the udev rules? |
Also, as it looks like you are using a snap - check you have enabled USB access. Either do this in Settings > Apps > SDRangel or run sudo snap connect sdrangel:raw-usb |
Stange this is that application works when there is noise only. I can see all graphs being updated. The problem becomes when I generate signal near antenna. I haven't observed this behaviour with Gqrx which works normally. |
The log file you sent shows that SDRangel isn't actually communicating the RTL SDR. If Gqrx works, I guess you have udev rules installed. But check the snap permissions - or send an updated log. |
Concerning usb access, I double checked it and it's granted. I've checked it in Ubuntu Software application. Concerning udev, I'm not sure how to check it fully, but with udev monitor it seems that rules are set. Example for attaching and detaching device: udevadm monitor
Currently sth changed (not knowing reason why) but I'm not even able to select this device as "Select sampling device" from SDRangel list while rtl_433 and Gqrx works without problems. Sure I run only ONE application at once. What kind of updated log should I send as I didn't changed anything? Here is my current log:

Well, the first log showed there was a problem communicating with the RTL SDR, which is why you couldn't see anything. The second log looks OK, so you should be seeing something. |
So it's exactly opposite. In the first case I was able to see noise but signal was causing software to hang. In the second, I was not able even to connect to the device... |
Hi!
I'm using SDRangel which is being recognized as
Realtek, RTL2838UHIDIR, SN: 00000001
Found Rafael Micro R828D tuner
I set it to direct sampling to approx. 100-150kHz frequencies. Every time I start using it, when generating a signal using external device and receiving it through antena, analisys stops without any visible error (acqusition stops) and if I run it from command line, I have the messages as below.
Any idea what could cause those problems?
