Hi,
I'm trying to connect some wireless sensors Iris Crossbow to read light and
temperature.
I must realize these three things:
1) I have to sample the light
and the temperature with two different times and I have to send the strings
everytime the signal is sampled. These things have to happen on the same node
and at the same time.
2) I have to sample only the light and I have to send the
packet.
3) I have to sample only the temperature and I have to send the packet.
1) and 2) are completed and the trasmission is correct, instead in 3) there is
a problem to read the value. The temperature reading is correct only in the
first sampling then is sampled a wrong value.
This is my code:
#include
"appFeatures.h"
includes XCommand;
includes sensorboard;
#include "vettore.h"
module XMDA100M {
provides {
interface StdControl;
}

The reception code there isn't here but I start the Timer (with
call Leds.start) in the reception.
Can someone resolve my problem?
Thanks a
lot...
