Hi Julian,
Thanks for responding so quickly! I've attached a picture of the current setup (if it gets through). I've tried looking at the output of the encoder and am seeing nothing come out of it and so there is no signal from that point on (through the gmsk mod->gmsk demod->decoder->tcp-sink). Is there something I need to do for the terminal messages I am sending through the tcp-source in order for the encoder block to properly process it?
I am currently just simulating it locally by going directly between the gmsk-mod->gmsk-demod as I wanted to make sure everything goes through before I add in the USRPs.
Thanks,

The packet decoder is checking for a preamble sequence in the data stream.
If there is no output coming from the decoder the preamble is probably not being detected.
How does the output of the gmsk demod look like?
Also, are you transmitting the signal or are you just simulating locally?
Cheers,
Julian
