BladeRF and MATLAB 2017a error

Post by samydh » Mon Dec 18, 2017 9:26 pm

Greetings:

I have just installed the latest version of the bladeRF for Windows 10 using the download link https://nuand.com/windows_installers/bl ... latest.exe

I follow the instructions, as directed. However when I attempt to run bladeRF_rx_gui.m in Matlab R2017a, I get the following error. Can someone please suggest what I am doing wrong?

Thank you.

Had the exact same issue and solved it by using the 2016 rc2 installer from here: http://www.nuand.com/installers.php
I did have to manually delete my bladerf directory from the drive though, the uninstaller/re-installer itself would leave the current matlab bindings that cause the issue, so had to remove them manually.

Hope this works for you.

--Edit---
When running bladeRF_rx_gui I encounter exactly the same errors/warnings - this appears to be the same as this thread: viewtopic.php?f=9&p=7628#p7628

I've now tried older libbladeRF and matlab bindings versions (that used to work) but am now still getting the same errors.
--End Edit--

After using the same latest installer, which uses libbladerf 1.9.0 I now encounter an almost identical issue with supposedly missing functions in matlab:

Though everything worked before the update... I'm using R2017 on Windows10 x64.

Could you list what files are present in C:\Program Files\bladeRF\matlab (or equivalent)? Seeing this for both 2016.05-rc2-alpha2 (the one that works) and 2017.12-rc1 (the one that doesn't) would be super helpful. Thanks!

I still can't attach images, but a text list is below. I will also emphasize I had to completely, manually, delete the C:/Program Files/bladeRF directory before running the older (2016.05-rc2-alpha2 ) installer to get it to work.

Just to doubly confirm: This is from the 2016.05-rc2-alpha2 installer?

If so, I think I know what I did wrong :shock: ... moving matlab/libbladeRF_thunk_pcwin64.dll into the x64/ directory should make 2017.12-rc1 work. I'll fix this up for the next build.

Yup it was bladeRF-win-installer-2016.05-rc2-alpha2 (unless I managed to accidentally rename something - which has happened before...). If you want an additional factor of confirmation, the libbladerf added by the installer is version 1.6.1.

Hey guys,

i have some simmular issues.
I can't get the bladeRF in matlab or simulink running. Matlab throws the same warnings as mando238 (Warning: The thunk(voiduint8Thunk) ...) .
I have installed some old Matlab versions and faced the same issues. I also have moved the dll to the x64 directory.
The bladeRF is capuring data via the CLI and works without any problems.
When matlab opens the device it throws the warnings and an "Error using bladeRF/load_library (line 308)
Failed to find functions in libbladeRF."
The device keeps running (LED2 flashing, LED1+LED3 on) until i close matlab, but i cant get the error code when closing.
To access the bladeRF after the errors its necessary to close Matlab.

My System:
Windows 7, fully updated
Matlab R2016a,R2017a,R2017b

This is a little different then what I encountered, but probably can be resolved the same way. 2 Questions first:
1. I see you have libbladeRF 1.9.0 - so I'm guessing you used the bladeRF-win-installer-2017.12-rc1?
2. Can you print out the contents of the directories?
- C:\Program Files\bladeRF\x64
- C:\Program Files\bladeRF\matlab\test
- C:\Program Files\bladeRF\matlab

Hey mando238, thank you for you reply!

I have tried it with the "bladeRF-win-installer-latest","bladeRF-win-installer-2017.12-rc1" and "bladeRF-win-installer-2016.01-rc1".
Right now i have the 2017.12 with the installer installed.

I added three screenshots from my Folders.

I have added the follogwing pathes to matlab:
C:\Program Files\bladeRF\x64
C:\Program Files\bladeRF\matlab
and i also tried it for some time with the additional path C:\Program Files\bladeRF


Thank you for your time.

Okay, looks like it wasn't at all what I thought it was. Try this installer, which can be installed over 2017.12-rc1:

https://www.dropbox.com/s/g72gdqpd65adw ... 1.exe?dl=0

Let me know how this works for y'all. Thanks for your patience and feedback!
