Re: [Discuss-gnuradio] Gettin data out from GRC to C++ or java?

Thanks for those tips. Matlab can handle 20M samples due to receiver object, which is buffering data, and than sending it to Matlab. My receiver is able to demodulate around 5x802.11 frames per second but i want something more faster. So i can use UHD driver in C++ enviroment directly right? Sorr

Ernest - here's an example of how to connect other stuff to GNU Radio via pipes - granted at much lower sample rates. Higher sample rates shouldn't effect the pipe, but Matlab may not keep up with a typical 802.11 sample rate. http://youtu.be/GBmli8Vflig?t=2m33s If you *could* get this 3k sample

So i if would like to create a simple flow graph, with USRP source and file sink only, is there any way to control file buffer size (i.e i want that any file consist of 3k 32complex samples every write)? Any 3.7 compatibile pipe pack? tried gr-pipe but typical "gnuradio-core" error :( -- View t

A pipe would probably be a better choice here, but yeah. Or you build your own custom blocks to interface with your other code. M On 10/16/2014 09:37 AM, Ernest Szczepaniak wrote: > So i can just constantly write data to file (with file sink) and open it in a > loop in any C++ enviroment right?

Hi Ernest, > Or it would be better practice to build receiver in grc and then plotting results out with UDP sink (already tried that, seems to be working)? that's a good question, and it depends on what you want to do, how much stuff you'd have to port etc. >Any way to output complex data collecte

Greeting, After building up some strong Matlab's prototype of my 802.11 receiver, I have to make really big and complicated GUI with lot of button's, plots, different tabs etc. And my question is simple: Any way to output complex data collected by USRP from grc to any other enviroment (c++ or j
