Jaeho, ieee802_15_4_oqpsk_phy *contains* the whole modulator/packetizer. With all the comments in the GRC, I think it's pretty clear which parts do what. You will simply need to integrate that same structure instead of the old _mod_pkt block; you can either do that by simply using the hier block that is contained in
ieee802_15_4_oqpsk_phy.py or you can simply just use the same blocks as the GRC in your applications. So: ieee802_15_4_oqpsk_phy is simply a block. Use it. It's not hard. If you have continued problems with using hier blocks, I recommend going through the guided tutorials 2 & 3: https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials It has two inputs, rx_in and tx_in, and two outputs, rx_out and tx_out, as you can see from the GRC. Connecting the USRP sink to the tx_out and whatever gives you the data you want to transmit to tx_in should do the trick. > or if you have more helpful manual or source code, can you send me those to > my email address? Um, I don't know how to put this, so I'll be blunt: The source code and architecture of gr-ieee802-15-4 are pretty clear, and the GRC files we're looking at here are especially well-commented; I'm afraid you will need to just try and use it a little more, and the problems you're having understanding how to use ieee802_15_4_oqpsk_phy might really point to you needing a little more experience working with hierarchical blocks, which is an aspect very central for GNU Radio development. I'm very optimistic you will manage to build something amazing! Have a look at transceiver_OQPSK.grc, it uses ieee802_15_4_oqpsk_phy.
