Error using loadLibrary

[harins12365]

Hello there,
I am trying to replicate exactly what you did in the HIL. All the simulations and code independent of the hardware work without any issues, but the HIL demo does not seem to work with a bunch of errors relating to "load library" and "DLL", where it either is having issues accessing my files or is running into other issues I don't understand. I was wondering if you had any idea on how to solve this or further discuss.

Thanks.

Hi, can you post the full error log? I don't have access to Matlab nor the BladeRF, but I will see what I can do.

after running HIL_demo.slx, this is what i get:

[JoseAmador95]

Have you installed the BladeRF driver? You can find the newest version in Nuands website. I used 2019.7 for this project which is not listed in Nuands site anymore but you can send an email to get it.

I'd try with the new version first. I think it fixed a compatibility issue I had with 2020 and newer.

Are you taking about the bladerf cli? In that case yes. Also I have attached a snip of the bladerf files that were downloaded alongside. If it is not this, is there something I need to download separately?

Thanks for your time.

Downloading the release sources is not enough. You have to run the installer attached as a release artifact.

https://github.com/Nuand/bladeRF/releases/tag/2024.05

Make sure to install the Matlab bindings and add the cli to the PATH. As far as I remember, it should appear as a checkbox somewhere in the install process.

Let me know if you have any questions!

Thanks for your reply.

I already ran the installer and setup everything, including adding the matlab bindings and and adding the cli to the matlab path and The Bladerf cli detected my balderf i was using.

The load library error was first seen after all these processes.

Do Nuand's examples using bladeRF.m (not mine) work? I have the feeling the issue is related to the availability of libbladerf.

[harins12365]

if you are referring to this one

when i get the chance, i can try to replace it with your bladeRF.m and see if any errors show up.

Thanks

[JoseAmador95]

Yes, that one. This is the original file I used to create the MIMO version. It will not work with my model, as it does not support MIMO. However, if you can run any of the examples in Nuand's documentation we can figure out whether the issue is in my MIMO version or in your system.

Let me know the results!

Hello Jose,

I tried running the examples in Nuand's documentation and i get the same exact error which I get before, so I think the cause for the error is something independent of the bladerf.m code.
