Look at the while loop in the code. Instead of reading from a file you can
substitute data
to be whatever you like.
use the following option to find out how to send data read from a file.
./benchmark_tx.py -h
This will display lots of options that you can use and one of them is the
file option. Y

If yes, then can I just use the "-S samplingrate" option while running the

I would just store the data using gr.file_sink and format it accordingly by
writing a routine. But if you want to build a block that stores the data in
the format you require then you can build a block yourself and add it to the

http://gnuradio.org/
The scheduler chooses the amount of data to process each time. Here it chose
4 the first time it ran the general_work() function and the next time it
chose 1. You can look into the scheduler's implementation to know how it

Hey!
I just switched to the latest versions (GR: 3.6.10, Ubuntu 22.04, UHD
4.3.0, Qt Creator 10.0.1).
I've just added an OOT module and block and could successfully build and
add it to the gnuradio and it works well.
To have a better graphical editor, I just want to develop in Qt editor
(qtcreator)
Hi all,
I'd like to use libgnuradio-filter in my OOT module/blocks.
I've read the following link which is about configuring OOT modules for
adding other parts of gnuradio:
https://wiki.gnuradio.org/index.php/OutOfTreeModulesConfig
I couldn't find the line:
set(GR_REQUIRED_COMPONENTS RUNTIME)
in
. Like so:

Hi all,
I made an OOT module named gr-tmo, adding some blocks and everything was ok.
But when I add another block which uses gnuradio filter (from
fir_filter.h), the whole module stops working
and even removing the faulty block using gr_modtool doesn't help, which
makes me start the whole module

Hi all,
I'd like to measure the round-trip delay (RTD) between two B200 USRPs. For
that, I send a raised-cosined-filtered, BPSK modulated PN-sequence, and as
soon as
I get this signal at the receiver, send back the same sequence from the Rx
to the Tx, and by correlation, I find the RTD.
The questio
I appreciate the information and advice you have shared and sincerely thank
you for the assistance.

Hi all,
I have two transceivers A and B each one is connected by cables to a USRP
B200mini (TX/RX for send and RX2 for receive)
Using GNU Radio, for each iteration, transceiver A starts to send a burst
of RC-filtered, BPSK-modulated PN sequence.
Side B waits for the burst and as soon as it gets t
