Hi Marcus,

We were using the UHD 4.2 release and had difficulties with getting the
timed commands to work on GNURadio as well as the UHD C++ API.

We reverted back to UHD 3.15 and it works now! Thanks for the vote of
confidence on the feature.

If we have time, we will try to reproduce the bug and share our results
here.

Best,
Raghav
