Hi
I was just trying to use interleave and deinterleave blocks. GNU radio
installed is 3.6.2
flowchar is something like
vector source
interleave throttle---deinterleave
---scope sink
vector source -
The datatype is byte. when execute the flowchart

Sandhya,
one quick question here: Is there really necessity to use 3.6.2
instead of 3.6.5 or 3.7?
Then: Ok, how do you come to the conclusion that sizeof_float would be
right for bytes?
And: I don't see any C++, where is your C++ problem?
The
oops instead of python i mentioned it C++ . Sorry for that .
Thanks

There are a lot of flowgraphs that have both hardware sources and sinks.
Why your's not working is a mystery to me, because, seriously, audio
sample rates should pose no problem for a moderately capable PC,
unless you do something

Um, yeah, I think I might have argued in another issue than you.
Ok, so the point is, what I thought you were proposing was a common

out of blocks; and I

Is there a way to make GNURadio pause before recording, and wait for the
user to start things? It takes a few seconds for my flow to start up, and I
would like to have control over the precise time it starts recording. For
example, I would run the flow, but the record would wait until I clicked or

Hi Paul,
use a valve together with some input widget.
There has been great discussion over how to build a valve system the
last month, you might need to read multiple threads to find the
solution that suits you best.

Dear All,
I am trying to transmit something and receive it back using the second USRP
N200 device.
However it fails, or I did not do it correctly.
I have two laptops and two (USRP N200, XCRV2450 db, 2 vert2450 antennas for
each)s.
GNURADIO v3.7 is installed to Ubuntu 13.04.
I run in the
It seems like I receive everything wrongly in the device. That looks like a
device problem.
Did you play around with the gain and see if that helps?
That did not help. The problem is that in the file '' the code always checks
for the value:

Thanks! Got that working with a valve and a button. However, my flow now
uses Volk machine, again, which doesn't record my data as well as it was
recording before the valve (and without Volk machine). Any way to keep it
from doing this?

Again, Volk has nothing to do with it. All that printout means is that your
flowgraph is now using a block which uses a Volk function for acceleration.
It has nothing to do with the problem you're seeing.

Hi,
I tend to agree with Marcus - if anything, this should be an opt-in
feature. I would prefer a combination of a setting per flowgraph or
generate.
As for the issue with modified python code: this could be easily caught
