[Discuss-gnuradio] reconstructing original data from GMSK loopback?

[George Nychis]

Hey all,

Is the proper way to reconstruct the original data back from modulating 
and demodulating with GMSK (in loopback fashion) by packing the 
outputted bits using gr.unpacked_to_packed_bb()?  Since there is 1 bit 
per byte (LSB), I'm assuming it needs packing.  Whenever I add the 
following block in the flowgraph:
gr.unpacked_to_packed_bb(self.bits_per_symbol(),gr.GR_MSB_FIRST)

... where bits_per_symbol() returns 1, I don't quite get back the 
original data before modulation.  Some of the bytes are correct, but 
most seem like garbage. What's my misunderstanding?

Thanks!
George
