Re: [Discuss-gnuradio] GNURadio on custom SDR platform / UCLA Zigbee PHY

[Martin Flasskamp]

Thank you very much for your reply! I'll write a GNURadio module for our
DB-SDR-Hardware to use it together with the UCLA ZigBee implementation.

As a reference system and maybe for future work we want to buy an
USRP/USRP2.  Which version do you propose?  The ZigBee code seems to
have been written for the USRP, but how difficult is it porting it to USRP2?

The Zigbee poject page ( https://www.cgran.org/wiki/UCLAZigBee ) says
the code needs GNURadio v3.2. Is it better to use that old version or to
port it to the current GNUradio v3.3.0? Or does anybody still working on
it and maybe sharing the code somewhere else besides CGRAN?

Regards,
Martin
