Hello everyone here,
I find if I do not use UHD, for example, when I use gnuradio-3.3.0 to
transmit files, the "ok=flase" when I set the bitrate greater than 600K or
less than 300K. However, when I install UHD and use gnuradio-3.5.0, I find
I can use the bitrate from 1M to 5M, why the uhd can lea
Hi,
Josh, Thanks for your help very much!
I use the file sink in C++ to verify the flow graph, as follows:
tb = gr_make_top_block("send");
file_sink = gr_make_file_sink(sizeof(gr_complex), filenamein.c_str());
tb->connect(amp,0, file_sink,0);
it run fine. but if I use the usrp sink, as follow

Hi，
Is there anyone who use the uhd source code like tx_burst.cpp, use the
function send(buffs, samples_to_send, md, timeout) to send data, I use the
tx_burst.cpp and rx_samples_to_file.cpp to transmit and receive data, but
the received data is without rules.
I think the data must be deal with
Hi,
Everyone here, I want to change the benchmark to pure C++ code and face
difficulty, that is, in rx: I connect all the C++ API and read a file which
product by benchmark_tx.py as file_source, but it does product any sink
file.
In the benchmark_rx.py, how it can know the USRP has received dat
Hi,
Is there anyone has changed gnuradio framework files to pure c++ code
,removed the python code, or has interested in doing this, I do work
recently but encounter difficulties, can I so lucky to reference someone's
information or get a hand from you?
Thanks very much !

Dear madam/sir,
It is my great honor to appreciate your works about GNURadio and USRP.
When I try to use the UHD driver,when I read the source code I have puzzle
about the use of the pure visual function for examples send(),
virtual size_t send(
const send_buffs_type &buffs,
