Hi Please forgive me if the questions are silly/basic. I've learnt a lot from replies on this forum and I'm making steps in the right direction, if only baby ones.
I am trying to implement a state machine based synchronization algorithm. The 2 states being "search for synch sequence" and "pass data through". As far as I can see, the ideal way to do this is to have the work function check what state it is in before proceeding. If it is in search state, the work function will search for the synch sequence and once found, switch to "pass data" and get out. Next time work is called (use forecast to make sure that the number of input items available matches the amount I have data I have after the synch sequence), it will pass data through. Switch state back to "search" and so on. My questions are these: 1. Before each work call, does GNURadio automatically know the state that I left it in in the previous call? (Am I allowed to make work return anything else apart from len(output_items)? 2. Is it better/possible to implement a separate block for the state machine that can somehow make the system aware of what state it is in? Thank you Anil
