[Discuss-gnuradio] sending ack back to sender upon receiving of data bits transmitted

[Joreen Tan]

Hi,
 
I have managed to send and receive data using benchmark_tx.py and benchmark_rx.py. To add on to it, is it possible to add acknowledgement so that once the receiver has finished receiving, it is able to send an ack back to the sender? I really needed help desperately. Any help will be greatly appreciated as after several months of exploring gnuradio, i am still unable to write any code.
 
Thank you so much!

Regards,
Joreen
