122-16 and GnuRadio 3.10x

[math_pitaya]

Are there any relatively straight forward ways to stream samples from a 122-16 device into Gnu-Radio(preferably 3.10x).

Have you tried the application at the following link?

I'm having the same objective, but no luck so far: have my new 122-16 SDRLab device, and followed these instructions exactly: http://pavel-demin.github.io/red-pitaya ... er-122-88/. Then in the trx_am.grc I replaced the source to be driven by an externally generated sine wave connected to the rx port 1 of the board and then to a frequency plot. No matter how I tried, the sine wave is not being received. Same problem on the transmit side: a sinewave generated digitally and then fed to a "red pitaya sink" is not showing up at the output - only some unrelated spurious components. Has anyone encountered this? The main reason I got this board is because I want it to be part of a staged SDR radio development, where parts of the processing will move to the board, and some will remain in GNU flowgraff. Can my board be defective? Perhaps it's missing some jumpers etc.? Any takers

Are you using frequencies above 300 kHz? The SDRlab has AC coupling and will not receive frequencies below 300 kHz.

[belotserm]

Yes, I'm using 600kHz center frequency

I can not get red_pitaya GR blocks to work. They run (no crashing or error messages), but no output. Is it possible the python version and/or GNU radio versions are newer than what this design supports? I'm on GNU Radio version 3.10.4, and Python is 3.10.6. Please advise

I was able to get rx working(mostly) on osx in Ryan Volz's radio Conda Environment.
OSX 12
GNU 3.10.5
Python 10.8
I had a lot of trouble getting the path variables correct.
I haven't tested the sink block, but RX was fine when I launched gnu by opening the trx_AM.grc script.
