It sounds like you are trying to transfer file from PC#1 to PC#2, connected via USRPs. At PC#1, user payload is read from a file on harddisk. This data is fed into a custom block. This block will start transmitting when certain criteria is met. When PC#2 receive the packets, it will send ACK back to PC#1. If this is what you try to accomplished, of course this could be implemented by gnuradio. There are thousands of such setup being tested using gnuradio. You should have told us the big picture, let us figure out the implementation details for you, not the opposite way. Forget about your initial python code because that limit us to dead end. > 4.

When you automate it you must have a calculation formula or decision algorithm. Please give a simple example of such calculation formula. Now I am still in the midst of trying to understand your requirements correctly. Meanwhile, please do not top-post.
