SV: [Discuss-gnuradio] fundamentals of block-connections, message queue etc.

Thank you both very much for your responses Doug and Colby. I have now gone
through the code in gr-usrp2 and usrp2/host thoroughly and I can see how the
data is handled before sent on to the processing blocks.
I can also see that the metadata is discarded at a point, and I found some post
in the archive about that this will be changed in later releases. I'm curious
if anyone knows if this is something anyone is working on at the moment?

As far as the usrp->gnuradio block goes - the frame to stream 'conversion'
happens in the usrp (or usrp2) source block (and on the tx side that similarly
gets hidden by the sink block). You can look in the gr-usrp (or gr-usrp2)
directories to see how that happens. But in general, you don't have to worry
about what format the samples get to/from the usrp in, that's taken care of by
the gr-usrp blocks.
For learning about some of the basics of GNURadio, I'd recommend looking at
some of the simpler examples (802.11 is not the simplest standard to deal with)
in the gnuradio-examples directories (the digital-bert example for example).
