Re: [Discuss-gnuradio] Find a Packet in a bit stream

[Daniel Batista]

Thank you Marcus,

I need something like the header/payload demux block.

Can you help my understand how it works?

The trigger input value can be the starting byte of my packet?

In header_data input should I insert the expected header?

Is it possible to  have a variable length payload?

Instead of defining the length of the frame is it possible to set a byte as the end of my frame?

Thank you in advance!

Daniel

Hi Daniel,

I think looking at the gr-digital/examples/OFDM example flow graphs will
help you.
