If your block is purely a message source, override start() and have it set
an flag, e.g., a pthreads condition or Python threading.Event. The message
generation portion (thread?) of your block should wait on the flag before
sending anything.
Otherwise, you would be sending messages out in response
Hi!
I am designing a message in-out OOT block that has a similar structure to
the Message Strobe. It is ought to send packets as soon as the Gnuradio
runtime permits. I realized that it is necessary to sleep the block off of
any work for a short period of time to surpass the "block::start();"
init
