How should I use GNU Radio on the ADRV9009+ZCU102 hardware platform

You need to provide a URI and not just the IP. Change the first argument in the block from 192.168.0.198 to ip:192.168.198

But I still have the same error after changing it like you said

what should i do？

The default driver name is not adrv9009 but adrv9009-phy. Please update that name. You can use iio_attr to explore the different device names, channel names, and attributes.

Thanks for your suggestion, now it works, but I have another question: can I change the settings of ADRV9009 through GUN Radio? If so, how should it be modified

At the same time, I still have a question, how to set the attr name to look like the next picture

I entered the same as displayed in iio_info in the cmd command window, but you can see that ERROR appeared in the lower left corner: "attr_source: warning: Reading parameter failed: -2"

why？

ok, I have already solved the attr name, I have informed my instructor, this is the setting after I changed, how do I display the time domain and frequency domain diagrams of the collected waveforms?

and a new error

1. ADRV9009 is configured through profiles generated from this tool: https://wiki.analog.com/resources/tools-software/linux-drivers/iio-transceiver/adrv9009#profiles Changing anything related to the sample rate will require a new profile

2. Your attribute block is reading sample_rate_avaible which is meant to show which values are possible. Since this shows 2 values this is essentially a string and cannot be converted to a float correctly

3. Reading the sample rate simply tells you the rate of the data and is not frequency data. This is done by taking Fourier transforms of time domain data from the ADCs.

Thank you for the information you provided, I will check it out later. Then how do I display the rx waveform on the gnu radio like an iio oscilloscope?

Use the IIO source block.

this one? How can I set these? I'm very sorry I just got into GNU Radio and am a novice
