Also....if you are not using the xbow/contrib code then do so...
I think the standard apps default to a low radio power, or
don't work in other ways similar to your experience. See the
xbow support site for download, and I think it's included on
install CDs from TOS1.1.10.

Thanks Dave, but, why the third mica2 listen the
others two? Because this one can listen the
transmission of the others two, and the others two
listen the transmission from the third. I send
broadcast messages, can the mica2 identifier (set at
install "make install.#") cause any problem?
thanks in advance,
José

I have found the radios on Mica2's are not that
reliable. Even on the
default frequencies, some of these motes do not
transmit at all.
Sometimes you'll get a good mote that transmits
correctly at the default
frequency - sounds like your 3rd mote did that
trick.
If you're using the same exact code on all three of
these motes and not all
of them work the same, the problem is most likely in
hardware. Test it with
different combinations to narrow down which mote(s)
are having the problem.
I've found about 30% of my mica2's do not transmit
correctly on the default
frequency (914.077 MHz).
The problem is due to the physical radio layout -
there is no impedance
matching mica2's.

Subject: [Tinyos-help] radio message problem
Hello all,
I have 2 mica2 motes, same code programed, and both
send messages through rf, using GenericComm
component.
None receive message from the other. I programm a
third mica2 mote to send & receive those messages
(same send and receive code, but different tasks),
and
this one receive from the others and the others
receive from the last one successfully.
So, both micas send correct messages, same code, but
doesn't listen. There is any operation that I must
do
or flag to set for receive? Any other idea?
