I think you are making wrong use of the unpacked_to_packed block:
I think so to. I was creating the file in Matlab, writing zeros and ones
as chars to a file, used that file as input to the flow- graph...
So to get my original code to work, I had to write "27" in the data file
(27 = 00011011b). Hence producing the four symbols I was looking for.
Why did my block work? It is packing the LSB from k bytes into one
byte... Kind of a "unpacked_to_unpacked_bb"- block... I think there is
some cleaning, polishing and asserting to be done in that code to have
it in "gnuRadio- shape", but if there is interest in such a block, I can
try to fix it up as good as I can, and post it.
Thank you very much for the clarifications, I've been guessing and
banging my head for a while with this.
