[Discuss-gnuradio] Error using Packet Encoder --> Packet Decoder

[Surya Agam]

Hello everyone,

I want to simulate file transmission using BPSK modulation, with block diagram

File Source --> Packet Encoder --> BPSK Mod --> BPSK Demod --> Packet Decoder --> File Sink

But the result is 0 kB. Then I remove the Encoder-Decoder and Modulation block.

File Source --> File Sink

Then I have the file and it's operable (-5 bytes from original file)

Next step I add Packet Encoder - Decoder

File Source --> Packet Encoder --> Packet Decoder --> File Sink

But the file size is 0 kB

I don't know what is wrong with the Encoder-Decoder.

Thank you
