Make sure you know what type of stream each block wants for
input/output. When I see that ValueError that you are seeing, it is
usually because I am trying to connect a block that produces a stream
of floats into a block that expects a stream of 8-bit chars, for
example. Sometimes the last two letters of the name are a clue...
"foo_fc" for example, means that foo takes in floats and outputs
complex. Absent this information, you may have to dig into the code to
find the stream types.
