Dincer,
Hopefully this will clarify things a bit:

resampling issue. Since gr-osmosdr will support USRP, the dl_scan
application should run using a USRP, but the sampling rate will be
incorrect and it will not decode

I'll take one of those, please. I can see how it might be a tricky
feature though. Do you aggregate existing variables, but allow
editing/viewing them from a single pane, or just scrap it all and have one
multi-variable block?

Hi,
So, when looking where to add the XInitThread call inside GR, for some
places it's obvious and for some it's not.
The gnuradio companion template is an obvious place. For WX, the
class stdapp is also a pretty obvious choice because a lot of
external app use that template and so will not
Hi all,
I'm looking for something like a buffer block to include inside a C++
flowgraph.
I'm getting samples off an USRP N210 at ~17MSamps/sec, and they enter
the flowgraph through an OsmoSDR source block. Unfortunately the
downstream block (openLTE) cannot initially keep up with the data
Hi Ben,
many thanks for your clarifying answer. I will need to think little bit about
2).
But I have another Question:
Why did you not use a usual Python flowgraph (like in file scan) but a C++
flowgraph?
Is there anywhere a python flowgraph for the live scan app?
Thanks again,
Dincer

Python flowgraphs aren't any more 'usual' than C++ flowgraphs. Python is
perhaps more widely used because that is how GRC generates flowgraphs, but
many applications, especially those that need

It appears that gnuradio.org is down. There's a domain name advertisement up
instead.

Hi Marcus,
Thank you for your reply,
What I am aiming ultimately is to estimate the time delay a packet could
have when running through the following path:
HOST(1) =[Ethernet]= USRP(1)[FPGA-DAC-AnalogPath-Antenna] == On the air
== The same path Reversed (USRP(2)) == HOST(1) or another HOST,
Hm. I suspect a DNS problem.
I get the domain advertisement page using Chrome, and get to the GNURADIO
webpage using Firefox.
I cleared both caches; same results.
Weird.

Slick, I always seem to end up with long linear chains of blocks that need
duplication on the page, your grouping mechanism could save me from having
to make so many custom hier blocks.

Perhaps the gr.copy() block will accomplish what you need.
Help on function copy in module gnuradio.gr.gnuradio_core_general:
copy(*args, **kwargs)
copy(size_t itemsize) - gr_copy_sptr
output[i] = input[i]
When enabled (default), this block copies its input to its output. When
According to the documentation comments, gr_msg_queue::delete_head_nowait()
should return 0 if no message is available. The current implementation,
however, results in a core dump.
For example, when executed in a script, the eleven lines:

Of course, if 0 is returned, msg2_out would not be an message instance, but
it would be possible to check if msg2_out == 0 before trying to call any
instance methods.

Hi Isdren,
I believe the correct implementation should the 'return 0' line uncommented and
the 'return gr_message_sprt()' removed.
That would not compile, since you can't convert int to boost::shared_ptr.
What you see in your python output are really only the swig wrappers of these

After some more thought I decided that what i want to accomplish can only
be done by rearranging the graph
in real time as for example in the selector and valve blocks.
I have tried a simple example and it works fine this way.
I will post a complete solution once I iron out the details.
thanks
