Must have at least one RF device

[MidwestTechnologies]

I have an issue similar to #112 but I did not see a solution there. I'm running three RTL-SDR devices on my RPi 3. The first two use rtl_tcp to feed other programs. I would like to use shinysdr with the third device. Each device has its own serial number. I believe the issue is with librtlsdr conflicting with gr-osmosdr. The following is my output when I try to run shinysdr:

WARNING:shinysdr:No network service defined!
INFO:shinysdr:Constructing...

exceptions.ValueError: Must have at least one RF device

I'm a novice when it comes to this and am hoping to learn. Please help! None of these web based controls hold a candle to shinysdr in my opinion.

"Must have at least one RF device" does not mean that no devices were found when you started ShinySDR. It means that your config-dir/config.py file does not define any devices. it looks like your configuration file might be missing other parts, because I notice it's also reporting No network service defined! — that is, the configuration file is missing config.serve_web(...).

You could edit the configuration to fix whatever's wrong with it, or you could create a new one with shinysdr --create. Maybe your config.py is just empty?

(In order to select a device by serial number, create the device like OsmoSDRDevice('rtl=yourserialnumberhere').)

I'll look into improving some of these error messages to communicate what needs to be done and/or what the source of the problem is, not just that a problem exists.

I believe the issue is with librtlsdr conflicting with gr-osmosdr.

If you mean that you had incompatible library versions installed, then yes, that would explain the problem. The config file generator makes the decision as to whether to include OsmoSDRDevice based on whether importing the osmosdr Python module succeeds at that time.

I think we can chalk this one up to a sloppy install. I had installed the config directory into my source. Thus the proper config.py file was not installed. I’m still not receiving any audio in Firefox despite allowing auto play. I’m not sure what is going on there. But for this particular issue I believe I will close it. Nice work. I think I’ll really enjoy shinysdr!
