 I'm working on Ubuntu 16.04 with UHD 3.12.0.0 and run the code in 
Matlab R2018a.

Does anyone know why this error may be caused?

Thank you in advance.

You should probably upgrade to the most-recent version of UHD that 
MatLab allows, since there have been many updates and bug-fixes since then.

  Also, Ubuntu 16.04 is really, really out-of-date.

Hi,


For receiving data using usrp,  sweeping a frequency range, following 
the code rx_multisamples.cpp, I am setting the frequency then doing 
START_CONTINUOUS; after receiving I am doing STOP_CONTINUOUS. After 
the code runs for sometime I am getting ERROR_CODE_TIMEOUT and the 
application stops. The we have to restart usrp to rerun the 
application. Please suggest solution.




I suspect that there's some system resource you're running out of that 
gets consumed every time you recreate these streams.


A better approach is to run the sample stream continuously, and change 
the frequency on the fly, and simply ignore a sample buffer or two 
immediately

  after you've changed frequency.
