Hi GP,
ofdm_loopback.grc covers only the physical aspects of the transmission.
What you are describing is a flow control problem; you'd need to figure
out yourself how to make your data stream fit into the packets. A
typical way would be to send the length of your file, and then just fill
up the l
When I ran the example ofdm_loopback.grc,
i used a file source to send data through the transmitter and checked the
output after the receiver in a file sink ;
i found that if the packet required to be sent is less than the defined
packet_length ; then the packet is not sent ?
how to send the last p
Hi Eskil,
QT has its own threading library that you'll need to use to spawn a new
thread to do the blocking calls in:
http://pyqt.sourceforge.net/Docs/PyQt4/qthread.html (sadly, that page is
still C++ centric)
PyQT4 usually comes with a set of nice examples, which have been useful
for me over the
Dear friends of GNU Radio,
I have a question about blocking, threads and GUI. Thing is, I am writing
an GUI application (in PyQT4) where the user can start a GNU Radio
flowgraph by a button. The flowgraph records data from an USRP and some
additional blocks. Now, I want only a finite amount of data

If you power-cycle in the middle of the burn, it's a great way t

gr-lte again it worked. I had installed gnu-radio from sources, so I
just updated it with git. Thanks!

Hi ,
I couldn't really tell the subject of this mail; I think it should be
"plotting data with the gr_plot_psd_c tool", is that right?
The axes should be labeled: X in the left is time (calculated from
f_sample, which is assumed to be 1Hz if not specified), on the right is Hz;
Y is amplitude (l
That cgran page says "GNU Radio >= 3.2.2", which indicates it might be
terribly outdated and would not work with 3.6.5 (it can't work with
3.7); I don't know if Nico has touched the code base since 2011, but I
assume you'll have to go great lengths to get it to work with current
GNU Radio versions.
Hello again,
My python code is actually inspired from "Packet Encoder" block
(/path/to/gnuradio/.../grc_gnuradio/blks2/packet.py) were I suffer
from the same issue.
I wrote that python script to make it very simple/short and confirm
the troubles.
I would be honored if someone could get a try on i
