Hi,
This post is perhaps a continuation of a previous post "Problems with MPM
3.13 on N310", but I wanted to change the subject to reflect this current
issue.
The issue is an Rx streaming timeout. It can be easily duplicated with a
stock Ettus example. Below you will find the console log which includes
the command line parameters. Note the following:
- I requested 31250 samples
- There is a error "Timeout while streaming" indicated at the end
- The final file size of 119340 indicates that 29835 samples were
received
- I do not have any reason to believe that the specific command line
arguments below are needed to duplicate the issue. I just didn't bother to
try other ones.
In the other thread, I mentioned that my Rx timeout issue had gone away
after switching to streaming mode STREAM_MODE_NUM_SAMPS_AND_DONE. However,
the issue below occurs when using that mode so it will be a problem for me.
Let me know if you have any questions.
Rob
