In fact I did it. In my module I use LowPowerListening interface and in
my configuration I connected it to RF230ActiveMessageC (or however to
Then in my Makefile I added the flag: CFLAGS="-DLOW_POWER_LISTENING"

The app works fine, but reading the TEP 126 and paper of the BoX-MACs
and analyzing the communication with the oscilloscope I got the question
about what could be the MAC used in the RF230 chip, because with a
resolution of 100ms/DIV the transmission seems to be continuous. I
thought it was BoX-MAC-1, because, reading the paper, it was the
protocol that most resembled the analysis done by the oscilloscope.
Now, you think that the protocol is BoX-MAC-2 and probably I'm wrong
because the resolution of the oscilloscope is too low.

Tomorrow I try it and then I inform you. :)
