Re: Failed to open SDRPlay device

Claudio,

GNU Radio 3.7.13 is a little old and I think you would be missing out of many new features and bug fixes of more modern versions of GNU Radio.

For Windows I would recommend using Ryan Volz radioconda distribution (see here for the instructions: https://wiki.gnuradio.org/index.php/CondaInstall) that would give you GNU Radio version 3.10.4

Once you have radioconda installed, there are two ways you can connect GNU Radio to your SDRplay RSP:

- using the native 'gr-sdrplay3' OOT module (see here: https://lists.gnu.org/archive/html/discuss-gnuradio/2022-03/msg00144.html)

- using the SoapySDR module SoapySDRPlay3 (for the build instructions see here: https://github.com/pothosware/SoapySDR/wiki/BuildGuide and here: https://github.com/pothosware/SoapySDRPlay3/wiki)

Let me know if you have problems with the installation or running it and I'll be happy to help you.

Ciao,

Franco

Good morning everyone,

I state that I am new to GNUradio, but I need to re-install in WIN10 a .grc program written by a colleague a couple of years ago, which uses the RSPduo SDR.

The hardware is fully functional, also tested with SDRplay's SDRuno native SW, but when I install it on the new PC with GNUradio, I always get an HW unreachable error.

GNUradio is in version 3.7.13.5_win64 which is the one suggested by SDRplay, I installed the API ver. 3.11 (SDRplay_RSP_API_Windows-3.11.exe), but when I try to run the program, I get a "Failed to open SDRPlay device" error.

I then tried the sdrplay_test.grc test program, which is a simple FM receiver accompanying HW, but I still get the same error.

I really need someone who can help me. If there is a volunteer, I attach the sdrplay_test file, the generated python file and the error message.

Thanks in advance for any suggestions and help you can give me.

Claudio
