Re: [Discuss-gnuradio] message passing test

Hi Neil,

yes, this can't work; you can only multiply two numbers if there are
two numbers (factors). Which will never be the case, since there has
not been a multiplication before the first factor.

Message passing can't make an flowgraph that has a synchronous path
("normal" sample flow) asynchronous. What you most probably want is to
receive the message with a block that e.g. sets the factor in a
multiply_const block.

Hope I could help a little,
Marcus
