[Avrora] Collection Problem

[rodolfo de paz]

Hi,

Yes, i updated the micaz code to fix some bugs and add better support. I've never tried MultihopOscilloscope with avrora but we have run in our group multihop simulations for micaz with an extension of the OpenZB code of TinyOS-1.x. So i guess it should be fine. Anyway, if there is any bug that you may find send it to the avrora list and i will also try to help.

regards,
Rodolfo.

Great.  That's a good start.

These days most of us use the Source Forge CVS version available at:

http://sourceforge.net/cvs/?group_id=215797

Even before that, try testing out the MultihopOscilloscope application
distributed with Tinyos 2.x.  That is known to work right out of the
box.

Okay, this may be part of the problem.  I don't know what the status of
CC2420 radio (used on the micaz) support is in Avrora.  I think that the
1.7 devel branch only ever had preliminary support.  Looking around in
the CVS version on Source Forge just now I see that Rodolfo of AvroraZ
has merged the CC2420 code into the Source Forge CVS.  Awesome.  I'll
have to give that a try...  But back to your problem.  I would
recommend:

- Test that MultihopOscilloscope works with mica2s on your setup (last
  reality check, this should work)

- Test that MultihopOscilloscope works with micazs on your setup (this
  tests how micazs in Avrora handle collection, I've not tested this but
  I'm guessing it works)
    - If it works then you can begin looking for the difference between
      MultihopOscilloscope and your application to see what you changed
    - If it does not work then you've isolated the problem to the radio
      stack and you can try your application with the mica2 nodes

Best of luck,
-Roy
