Re: [Discuss-gnuradio] PDU Socket Configuration (was: [USRP-users] PDU Socket Configuration)

Hi Steve,

this is really a GNU Radio issue, not a USRP issue – so I'm cross-
posting my reply here and there, and I'd ask you to sign up for the dis
address@hidden mailing list[1] and follow up there.

To make this short:

Nowhere – you sent them to a socket.

You receive them with a socket.

GNU Radio PDUs are PMTs:

It doesn't accumulate anything!

So, I'm afraid that working with PDU sockets requires basic
understanding of how UDP or TCP sockets work; you'll need that
knowledge, anyway, if you're about to build networked applications, so
I'd recommend reading up on UDP (for example, Wikipedia's article is
pretty OK), and on UDP sockets.

Best regards,
