I am trying to figure out how I control a Software Defined Radio over a network, and stream the received baseband samples from my remote hardware back to the gnuradio.

What I'm trying to do here is, this Python code should be able to output a user selectable waveform which can be a CW tone, Broadband Noise, or an arbitrary waveform read from a file containing I/Q values.

So I searched on the internet and the closest thing that I found was the BorIP and unfortunately couldn't get it set-up on my machine because the instructions I found were not helpful (at least for a beginner like me).

I created the Python web server using this script (which I found online):

    import http.server

import socketserver



PORT = 8080

Handler = http.server.SimpleHTTPRequestHandler



with socketserver.TCPServer(("", PORT), Handler) as httpd:

    print("serving at port", PORT)

    httpd.serve_forever()

But didn't know how to merge the generated gnuradio python code into the Python web server.

GNU Radio Companion (GRC) generates Python code that is something like this (not exact text). (Make sure you chose the "No GUI" option in GRC.)

class my_block(gr.top_block):

    # ...



def main():

    tb = my_block()

    tb.run()



if __name__ == '__main__':

    main()

You can just import this as a module in your Python program (the if __name__ check will skip running the code that wouldn't be appropriate). Once you've done that, the way you use it is to just create the top block and call tb.start(). This will start the flow graph without also waiting for it to finish, which is exactly what you want when you have a separate main loop like a web server.

import my_block



tb = my_block.my_block()

tb.start()

When you're shutting down, do this to stop the GNU Radio threads:

tb.stop()

tb.wait()

Then you can also use the generated methods (a getter and setter per GRC "variable") to change parameters while the flow graph is running.

There's a lot more that can be said about how to go beyond what GRC generates for you (which would best be asked as separate questions), but this is how you get started with integrating a GNU Radio flow graph into a larger program.

I would recommend expecting to eventually stop using GRC's code generation and write your own Python code. This is because GRC has quite a few limitations in what you can do with it — for example, if you want to decide at runtime which type of signal source block to create, you can't do that in GRC but it's easy when you write your own Python. You can always use GRC to generate examples to copy from, when you're unsure how to configure a block.
