Hi,
I'm using USRP N210, and I have some confusion on the overflow indication.
For each "O" UHD outputs, does it mean: 1) I missed one sample 2) I
have missed some samples during that recv() call?
And what does it look like in the received buffer?
Say if the transmit sequence is: sample1, sample2, sample3, sample4,
sample5, if overflow happens at sample3 on the receiving side,
Would I get: sample1, sample2, sample4, sample5 ...
or
Would I get: sample1, sample2, random sample, sample4, sample5....
Thanks,
Qski

Here is the explanation (basically, loosing a packet of samples):
