How to add rtl-sdr device?

[andruxa-smirnov]

rtl-sdr installed, but in source list of sdr devices not present. Log of rtl_test: $ rtl_test Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN:

Using device 0: Generic RTL2832U OEM Found Fitipower FC0013 tuner Supported gain values (23): -9.9 -7.3 -6.5 -6.3 -6.0 -5.8 -5.4 5.8 6.1 6.3 6.5 6.7 6.8 7.0 7.1 17.9 18.1 18.2 18.4 18.6 18.8 19.1 19.7 Sampling at 2048000 S/s.

Info: This tool will continuously read from the device, and report if samples get lost. If you observe no further output, everything is fine.

Reading samples in async mode...

Hi. Seems it needs the SoapySDR + SoapyRTLSDR.

SoapySDR is an abstraction layer that provide support for various SDR hardware.

See here: https://github.com/pothosware/SoapySDR https://github.com/pothosware/SoapyRTLSDR

Hope it will help.

Yep, in the end, SigDigger just wraps around SoapySDR in order to detect SDR devices. Installing Soapy's rtl-sdr module should make it work (you shouldn't need to recompile in order to do this, it would be enough by installing the missing modules).

How to install the missing modules?

[BatchDrake]

@ganlubbq it depends on how you've installed SoapySDR in your system and the specific distribution you are using. In Debian and recent Ubuntu releases there should be a package named something like soapysdr-module-all (the exact name may be different) containing all the modules you may need.

[andruxa-smirnov]

Hm. Soapy (self and modules) was installed, but no rtlsdr modules appeared

Any ideas?

These messages are simply saying that, although the bladeRF module is present, it cannot be used as source because it is not detecting any bladeRF device.

Unless you've plugged a bladeRF device, this is not an error.

I also have this problem, I have SoapySDR installed on Ubuntu 18.04 My RTL2832U is discovered however I only see "Dummy Device" in the AppImage

Mmh, I thought I fixed it in the last release, but maybe I'm still missing something. Tests in my Ubuntu 16.04 (release 0.0.5) worked well, both with RTL-SDR and AirSpy. What AppImage release are you using?

I believe it was 0.0.4-alpha I will try 0.0.5-alpha tonight and report back. Thank you.

Since debugging AppImage problems is starting to become a little cumbersome, I'm going to open a feature request to add a debug option to check whether modules are being loaded right. I'll keep you all updated.
