sorry, I don't know about MoteIF, but if you look at the impl of
the reset message in OscilloscopeM.nc you see that it just resets
the reading number:
/**
* Signalled when the reset message counter AM is received.
* @return The free TOS_MsgPtr.
*/
event TOS_MsgPtr ResetCounterMsg.receive(TOS_MsgPtr m) {
atomic {
readingNumber = 0;
}
return m;
}
What you probably want to do is get the timers started at the same
time, which I suppose you could do by moving the:
call Timer.start(TIMER_REPEAT, 125);
to the reset message. There's probably some nice way to restart
the timer but that would require a lot of code archeology to find.
Also it's likely that the timers will not all start at exactly
the same time, and will drift anyway. Depending on what your
objective is, there may be some more robust distributed way of
designing it...

Hi,
then what MoteIF is doing? according to the documentation it is
used to send and receive msgs to an from motes. And this is used in
reset class to send a reset msg to the motes.
If the oscoperesetmsg is an arbitrary method, then how to make a
function which will act as a software Reset for the motes. So if I start
motes at different time and the use this s/w reset it will start them
again and the motes will be synchronized.
thanx

It's an arbitrary function conveniently labeled so as to make
it look like it does something useful. If you look at the impl
in O'scope all it does is reset the message counter.
You can, of course, make it do something more interesting...
