Hi Marcus
Thanks for your answer. I am restructuring the design of my OOT block.
I'd like to ask a last question about it...I am trying to send some commands (array of bytes) to an external hardware only ONCE before starting with my real time data acquisition . The problem is that if I implement the sending of the commands in the general work of my block, the commands will be sent each time the general work finishes and starts again. My solution proposed is to begin the execution of my flowgraph and send an external signal (specifically kill -SIGIO PID) from terminal to call the implemented method which sends the commands, so that my general work will only focus on the data acquisition and I will send the commands only once.
My question is: Is there a facility or tool that GNU Radio gives me to solve this situation? There should be a more suitable solution.
Any help or recommendation would be appreciated.
Thanks
Regards
Isaac.
