Re: failed to use matlab command "bladerf_rx_gui"
The error message seems to suggest that the system cannot find a bladeRF:
Are you able to use the bladeRF-cli program to open the device? If not, then it sounds like you may not have either the libusb-based or Cypress CyUSB3 driver installed. (You need one or the other -- whichever you decide.)
Alternatively, you may see this error if you are running a different program that currently has elusive access to the device. When this is the case, you'll usually see a blinking LED on the bladeRF.
Code: Select all

Re: failed to use matlab command "bladerf_rx_gui"
cause bladeRF cannot be accessed by to interface simultaneously ,i just close one of them.jynik wrote:Nice job! Mind sharing the details of your solution so that others may benefit from it?
then matlab can detect the bladerf.

Re: failed to use matlab command "bladerf_rx_gui"
Greetings,
I'm experiencing similar issues with matlab 2014b. When I try to load bladeRF_rx_gui it returns a bunch of errors:
So far I have tried reinstalling the drivers (both WinUSB and CyUSB3), add path for matlab, using an older version of libbladerf and even trying a different version of matlab, 2015b to be exact.
BladeRF x40 runs nice with SDR-Radio v3 but I would like to use it on matlab's simulink in order to make a wide band spectrum analyzer using I Q data.
Since I can't even run the example provided, as expected I can't run the bladeRF's function block on matlab either.
I have used in the past, an Ettus N210 USRP for similar purposes, without any problem.
At first I thought that it was a USB 3.0 incompatibility, but CLI along SDR-Radio works like a charm.
Does anyone else had similar issues? Any suggestions?
Thank you

Re: failed to use matlab command "bladerf_rx_gui"
I might be getting the same thing with the most recent installer. Were there warnings surround your error listing the specific functions missing? If so can you post the too?

Re: failed to use matlab command "bladerf_rx_gui"
I had the same issue with the missing functions, See my solution in this thread - viewtopic.php?f=10&p=7627#p7627

Re: failed to use matlab command "bladerf_rx_gui"
Greetings...
I have a new build that should hopefully work... if you could, please give it a try and let us know how it goes.
The link to it is over in another thread: viewtopic.php?f=10&p=7627#p7698
Thanks! -rt

Thank you!
It works fine under Matlab 2015b

Re: failed to use matlab command "bladerf_rx_gui"
I got the same errors when I tried to run bladerf_rx_gui.m. The problem occurs when I run bladerf.m first. If I restart Matlab without running bladerf.m, then bladerf_rx_gui runs just fine.
