Connecting "PDU to tagged stream" to modulator

GNU Radio

Hi,

I’m trying to work out the best way to connect a “PDU to tagged stream”
block
to a modulator.

I presume you can’t simply attach the “PDU to tagged stream” directly to
a
modulator.

So I was thinking of doing:

Tun tap pdu -----> PDU to tagged stream —> packet encoder ---->
modulator

However the problem is then the fact that the packet encoder outputs and
requires fixed length frames, which the tun tap pdu doesn’t provide (as
they are variable length).

Anyone got any suggestions?

Kind Regards,

Chris

By a modulator, do you mean a bit -> complex symbol mapper?
There’s no reason you can’t directly connect these. Have another look at
the tagged stream manual page: You can connect a tagged stream to any
non-rate changing non-tagged-stream block.
