I can't detect USRP X310 with UBX-160 Daughter board in MATLAB.

I am trying to connect USRP X310 with daughter board of UBX-160 with MATLAB 2024a. I tried Wireless Testbench™ Support Package for NI USRP Radios to detect my radio but it gives me error.

By using the findsdru command I see the following output.

I am not sure what to do? Anyone can help?

[Walter Roberson]

My suspicion would be incompatible firmware releases. Perhaps the X310 has a firmware release that is later than the supported version.

[Gavin Grant]

Thanks Walter, that could well be the case. The output of probesdru should indicate firmware version, so we can check that.

Best regards,

Gavin

Muhammad,

Thank you for reaching out about the issue you encountered.

Firstly, could you please share the output of running

probesdru

This will help us confirm the radio motherboard and daughtercard info.

Secondly, could you please share the output of running

rx=comm.SDRuReceiver(Platform='X310'); rx();

This will help us narrow-down where the validation failure is coming from.

I notice from your screenshot that your radio already has a name MyX310. Did you manage to successfully validate the radio previously and save it, or did you save it after skipping validation?

Best regards,

Gavin

Thank you so much for your time and valuable comments. I come to know that while performaing the steps

I made mistake in Configure FastSendDatagramThreshold Registry Key

I mistakenly appended the space to FastSendDatagramThreshold registery value by copying. I can validate my USRP now.

Muhammad,

Thanks for letting us know and very glad you have it working now.

Can you confirm that you have a UBX-160 daughtercard (sharing the output of probesdru would be super helpful)? The reason I ask is that if so, you may use additional functionality within Wireless Testbench, as detailed in the table within the doc: https://mathworks.com/help/wireless-testbench/gs/supported-sdr-devices.html (Prebuilt Hardware Images and HDL Code Generation for NI USRP Radios).

Best regards,

By running the probesdru, I got the following output which confirms that daughter board is UBX-160.

[Gavin Grant]

Great - thank you.

Just to let you know that the Hardware Setup App (HSA) now performs the registry key step automatically, so this manual step was not required. For more details on the HSA, you can refer to: https://uk.mathworks.com/help/wireless-testbench/ref/radiosetup.html

To clarify, support for X-series and N3xx-series devices was transitioned from the existing USRP Comms support package to Wireless Testbench in R2024a. Therefore we recommend you use the Wireless Testbench documentation which explains how to use the additional functionality available, such as support for Prebuilt Hardware Images and HDL Code Generation for NI USRP Radios.

Best regards,

Gavin
