Issues using "Correlata and Sync" block, inside Hier_block2

GNU Radio

Hi everybody,

I am writing here because I am experiencing an issue (for some weeks
now),
and I can’t fixed it! I did some research about this problem, but I
found
nothing!

I want to develop a hierarchical block, (called “RX_PATH”). In this
block,
I want to use the “Correlate and Sync” block… And here is my problem!
When I compile my module (using make), all work well. But, when I run my
.grc model in GNURadio-Companion, it’s like the “Correlate and Sync”
block
freeze.

Actually, no samples are outputted (neither in “out” port nor in “corr”
port). I don’t understand why, because when I use the “correlate and
sync”
block outside my hier_block, it work fine!

I think, this is a misunderstood of how to use these type of blocks, so
if
someone could explain to me where is my mistake, I would be very
grateful!

Thanks in advance!

Marius

That definitely sounds like unexpected behavior, and I can’t think of
much
to say right now about what might be going on.

However, we are deprecating that correlate_and_sync block in favor of
the
corr_est block. There are a number of improvements in corr_est, and
something in the scheduling might work better for you because of that.
