Re: [Discuss-gnuradio] Announce OOT module for IEEE-802.15.4g MR-FSK

[Wayne Roberts]

The GRC flow graphs are in the examples subdirectory.

There is a local_loopback example, which tests all the blocks without any hardware.

And there is one for testing UHD sink as transmitter, and another for UHD source as packet receiver.

I use USRP-B100 talking to CC1200 radio chip, and the mrfsk_TX.grc generates identical packets.

qa_mrfsk_pkt_sink.py currently doesnt do anything because the individual framer sinks are tested by themselves.
qa_mrfsk_pkt_sink.py would only need to test the code in mrfsk_pkt_sink.py, which is only connecting the correlate_access_code to the framer sinks.

I will later study pyBombs.

btw, this protocol is used at www.wi-sun.org

Hi Wayne,

and thanks a lot for publishing this!
Perhaps you can submit a recipe for PyBombs?

I had a very quick look at it (I don't really have anything to test it
with). One of the QA codes (qa_mrfsk_pkt_sink) doesn't work properly, it
uses the installed version to test.

Some more suggestions:
- Can you add a full UHD-to-bits GRC flow graph in apps/ ? That would
  help people see how it all works together.
- Perhaps you can add an IQ capture to test the code without having a
  transmitter nearby? I'm not sure of the overall bandwidth occupied,
  but if it's not too big, that might be useful.

Cheers,
Martin
