Re: [Discuss-gnuradio] tcp and udp server
I implemented a tcp source and sink in grc. I only tested it between two flow graphs on the localhost, so give it a try. -Josh feldmaus wrote: Hi All, i am read something about "sending data over tcp". as i can see in grc there is only an udp sink.

See this nice python networking tutorial :
http://heather.cs.ucdavis.edu/~matloff/Python/PyNet.pdf
BTW, the author of this tutorial has also a great python tutorials which can be
very useful for gnuradio beginners such as:
http://heather.cs.ucdavis.edu/~matloff/Python/PyThreads.pdf
http://heather.cs.ucdavis.edu/~matloff/Python/PythonIntro.pdf
Also for general python programming :
http://heather.cs.ucdavis.edu/~matloff/Python/pyMPI.pdf
http://heather.cs.ucdavis.edu/~matloff/Python/PyIterGen.pdf
http://heather.cs.ucdavis.edu/~matloff/Python/PyFileDir.pdf

Trust me, setting up the sockets is so much easier in Python in C++.

Might be nice to abstract it into its own block for the people that
just want to slap it together.

No need. Use python to open the appropriate file descriptors, then
use gr.file_descriptor_{sink,source}

Hi All, i am read something about "sending data over tcp". as i can see in grc there is only an udp sink. Is there still a tcp sink ? regards markus ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
