Hello.
I'm trying to setup a X300 USRP to use with the MATLAB Wireless Testbench Add-On. After running the radioSetupWizard command, I get the following error when performing the validation:
---
Output argument "status" (and possibly others) not assigned a value in the execution with "wt.internal.hwsetup/RadioToneValidationHSP/loopbackTone" function.
---
I'm using MATLAB R2025a, with all the add-ons the the installation of MATLAB itself up to date. Also, I'm running uhd_usrp_probe version 4.6.0.0. I'm able to ping the USRP at the default address 192.168.10.2 in the terminal, and uhd_usrp_probe can find and display info about the USRP both in the windows terminal and in the MATLAB command window using findsdru('192.168.10.2'). I also tried turning the firewall on and off again in the control pannel in windows since I saw that suggested in another question here and in the Common Problems and Fixes documentation, but it didn't help.
Any help would be greatly appreciated. Thanks!

Hi,
I ran the command you provided, and got this result, as expected.
'[INFO] [UHD] Win32; Microsoft Visual C++ version 1936; Boost_108100; UHD_4.6.0.0-vendor

[WARNING] [X300] For the 192.168.10.2 connection, UHD recommends a send frame size of at least 1472 for best
performance, but your configuration will only allow 1468.This may negatively impact your maximum achievable sample rate.
Check the MTU on the interface and/or the send_frame_size argument.

Check the MTU on the interface and/or the recv_frame_size argument.
