Hi Dave,
if you need a block that just passes messages, try the Message Strobe. If
this is not what you want, can you please publish your block code so we can
reproduce the behaivour? From your error message, maybe you have forgotten
to put the "self" parameter in the method declaration? That is always
needed in python as first parameter of class methods.
Also, when you want to test flowgraphs with PMTs, you can't use
"self.tb.run()" but have to use a structure like this:
# connecting and block instancing
self.tb.start()
time.sleep(0.5)
self.tb.stop()
self.tb.wait()
# assertion checks
This lets the flowgraph run for 0.5 secs and stops it again.
Cheers,
Sebastian
