[Discuss-gnuradio] 802.15.4 how to forward a parameter to a c++ block

[bjoernm]

Hi,

I'm currently using the UCLA ZigBee PHY implementation posted on:
https://www.cgran.org/wiki/UCLAZigBee
with gnuradio.

My question is the following:
How can I forward a parameter from: src/python/ieee802_15_4_pkt.py
... e.g. from the "send_pkt(...)" function (or any other)
to the c++ block in : src/lib/ucla_symbols_to_chips_bi.cc ?

Or more generally speaking: How can I forward a parameter from a  
python application to the c++ processing block?
If possible it would be great to use the io_signatures...

best regards and thanks a lot for your help,
Björn
