Hi Thanasis,
1. The flow you showed could not have worked because Packet Decoder
takes unpacked bytes. The graph should be:
File Source -> Encoder -> Packed-to-Unpacked -> Decoder -> File Sink
2. The payload length defaults to 512 if you leave it at 0, so a short
file won't fill a packet.
Encoder:
1 Sample/Symbol, 1 Bit/Symbol, Payload length 1
Packed-to-Unpacked:
1 Bit/Chunk, MSB
That worked for me.
General question for others ... the encoder/decoder are part of GRC and
haven't had any substantial work in a long time. Is this code meant to
be used, or should people look at other blocks, or gr-mac?

I am seeing the same problem here while running some tests.
Anyone else has any thoughts?
Running gnuradio 3.7.5, installed with the build-gnuradio script on
Ubuntu 14.04.

Hi,
In the followning basic setup:
File Source (Byte) ----> Packet Encoder (Byte) -----> File Sink (byte)
My input file is just a "Hello World" message
If the Repeat property of my file source is set to "No" the File
Sink remains empty Why? Do I have buffering issues?
If I set Repeat="yes" file sink seems to work, But when I insert a
Packet Decoder:
File Source ----> Packet Encoder ----->Packet Decoder -----> File Sink
The output file is empty again!
Thanks
