[Discuss-gnuradio] Re: UHD problem.

[Josh Blum]

If the frames are contiguous and each packet as EOB marked, then every 
other packet will be a late packet and discarded. A solution is to gain 
the capability for the timestamps to be honored in this case with future 
FPGA modifications. May they come soon.

If there is no EOB on the previous packet, then the timestamp on the 
next is ignored and samples are send contiguously. However, if you 
suffer an underrun, the contiguity is lost. This is where reporting of 
underuns and errors of the such to the host would be useful. This is a 
task for me in the near future.

I currently dont recommend the mimo sink block as of yet because of one 
of the two issues above. I hope that explains what you are seeing. And I 
hope to resolve this capability soon. -Josh
