Error using Packet Encoder --> Packet Decoder

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

Regards, Surya A.

Have you set the preamble and access code? The “leave blank for
automatic”
didn’t work for me.

I try different “random” access code and preamble but the output still
0kB.
Would you mind to give an example or reference about it?

For testing whether it works, just set them to a bunch of 1-s and 0-s.
the relevant Wikipedia articles for relevant articles :smiley:

access code = blank
