Bob,

Saw this the other day, but there isn't a lot to go on here. If block2 is your own, you can make it do the bypass. You can also use some of the logic blocks and a multiplier depending on what you're doing. There isn't really a concept of on-the-fly switching in GNU Radio.

      I have following flowgraph:


    usrp_source--->>probe_mag_squared_block---->block2--->block3

    What I want to do is that I want to bypass the "work" function of
    block2 when the threshold level of probe_mag_squared reaches. I do
    not want to stop(), lock(), disconnect the flow graph. Is this
    possible using stream tags, or message passing etc ? Any example
    code would be nice.
