Hi all !
I've been working on this flowgraph for a while now and I've been able to pinpoint what is not working, but I don't understand how to resolve this so, that's why i'm asking for your guidance.
Take a look at the flowgraph i've joined. The thing that doesn't seem to be working on this setup is the samples/symbol in th CPFSK mod block.
When I set this parameter to 1 i'm able to retrieve my message at the file sink. So it tells me that what I did is okay in
some way.
What is not working is when I set the same parameter to 6. At the beginning I wasn't using the rational resampler and it wasn't working. So I thought I would need something to "divide" the number of samples to retrieve each symbols. I tried it with the rational resampler block and set decimation to 6, but then, Daaaaaah......not working again.
There is something I can't work around here because I do not have sufficient knowledge about this samples/symbol thing.
