Goodmorning list,
thanks to everybody for your replies.
I attached a minimal example illustrating the problem.
Specifically, the block that causes the non stop behavior is the

the other replies.

Goodmorning,
I would like to Know some methods to Close flowgraph automatically when
it has finished. Some example, stop when USRP has no more samples to
transmits, or a file source has read until EOF.
The Run of completion option works when (for instance) you have a file

I'd like to know if there is a way to execute multiple flowgraphs
sequentially.
for example, the first flow graph transmits data from file, when it
finishes, the first flow graph becomes inactive, while another flow

I read an interesting paper on ControlPort to inspect the performance of

I tried it and it's a very powerful toolkit, thanks for the release.
Actually I want to remote monitor a target machine in which the simple

I have general questions about processing a fixed number of samples.
In front of the necessity to process N samples (N=8192 items) in a

here a link where there is an example about how to use UHD class.

Give me a feedback if you are able to use this class in our own block.

Hi,
I'm trying to install gnuradio with Build Gnuradio Script on ODROID-XU .
First of all, when the script looks for libraries, a first error occurs for
libqwtplot3d-qt4-dev, and it seems that there is no package available for
ODROID-XU.
eated block!

Hi,
I created a C++ block with gr_modtool,
following the commands:
$ gr_modtool newmod PWagc
$ gr_modtool add -t general power_control
I written and compiled my block with commands:
$cmake ../ && make && sudo make install && sudo ldconfig
Until this point all seems ok, but when I open gnuradio
