[Discuss-gnuradio] Packet Decoder block malfunction after demodulation!

[Vlad Stoianovici]

Dear list,
I'm using a typical UHD USRP source (USRP2) --> Low-Pass filter --> GMSK
Demod --> Packet Decoder --> File Sink receiver flow-graph in GnuRadio to
receive the signal I'm transmitting with a mirrored transmitting flow.
The problem is that the Packet Decoder (Output type - "byte"; Access Code -
field left blank; Threshold -" -1") doesn't really do anything, the signal
streams blocks there, and the file that the File Sink should create with the
data from Packet Decoder is always empty.
The rest of the flow-graph seems to be working properly, I can visualize the
received signal, that seems to be the same as the transmitted one.
If I take out the Packet Decoder, the file that results form the File Sink
has a size larger than 0 bytes, which leads me to believe that the problem
is with this block.
Any ideas or similar problems?
Thanks,

Vlad.
