GNU Radio supports hierarchical blocks with no inpu
Hi!
Only blocks connected to the global top block get run; your no inputs/no
outputs hier block doesn't get connected to the global top block, and
thus, neither do the "contained" blocks.
Best regards,
Marcus

*Problem and Question*
It seems that a file source in a hierarchical block doesn't start
automatically as it does in a top block. I ran into this problem with a
larger block of code, but was able to isolate it. I tested with both a
number sink and a file sink and neither showed any activity coming
Johannes,
The 140 came from this datasheet
https://www.ettus.com/wp-content/uploads/2019/01/USRP_N310_Datasheet_v3.pdf
It does indicate that this is probably a worst case scenario, and that UHD
software would improve it.
My flow graph has two separate parts, one for the TX that goes to a USRP

Hi Cameron,
where did you find this 140us switching time? I'm curious.
If I recall correctly, my tests with N310s indicate 18us delay between
TX and RX with timed bursts at sample x and corresponding start of burst
in RX at x+18us. The behavior you observe seems to be different.
How does you
Hi SDR community with the highest dynamic range!
We're having a project call today; it's on twitch.tv/gnuradio , and
later on Youtube.
If you're having something you want to acutely discuss, do reply here or
on #general on the GNU Radio matrix server or in #gnuradio on freenode.
Cheers, and see

Hi Martin,
Thanks for the response!
The OOT module compiles when I do: cmake ../ and make, however, the QA test
fails and gave the following error warnings
File "" (for different lines in this imported
file)
Now what is also disconcerting is that if I try to run another QA test that

That's not the full error; without the full error, it will be hard to
help you.

George,
all the usual linking and compilation rules of C++ apply. There are plenty
of blocks that call other functions from general_work() or work(). If
you're compiling a-OK, then you're probably halfway there. Your QA code
