Re: [Discuss-gnuradio] Error on GNUradio

[Ricardo Nuszkowski]

Thank you!

I’ll try with QT and see if I am still getting errors. I will also post this on the myriad forum.

Hello Ricardo Nuszkowski,

Sorry, I forgot to edit my e-mail before sending it out: you probably should ask this to MyriadRF guys first, and then move to other forums.

Hello Ricardo Nuszkowski,

The error messages are saying that it failed to initialize your radio hardware properly. It is either gr-osmosdr or SoapySDR (I think this is more likely), not really (the main tree) GNU Radio's fault. I recommend asking the same question on their mailing lists or forums as well. (I think myriadrf is the right place to ask).

The first error message is probably related to this:  https://discourse.myriadrf.org/t/limesdr-arrived-but-cant-get-it-to-work/744/11

I am not sure about the second error message - it does complain about your sampling rate settings, though.

When the failure happens, the Osmocom source is automatically replaced to a null source, which does nothing. So, you will get an empty WX waterfall window. (by the way, I suggest considering QT waterfall or QT-fosphor, as WX GUI is not supported well anymore.)

Hello,

We will be running a basic flow graph to test our antenna with the LimeSDR.

The flowgraph is basically an osmocom source--> WX GUI waterfall sink.

It will run perfectly fine for some operations and then every once in a while we will run it and get this error. It then works fine after we hit the reset button on the LimeSDR.

We will get this error.

If anyone knows what is going on, that would be great.
