Perhaps you need to pass different strings to unique() in order to get different values out of it?  What I am implying is that all three of the timers you wire below may resolve to the same timer because you give them all the same name.
...not that I have any idea how unique() works, of course.

hi all,
 
i encounter a strange problem: the time auto to fire without any "call timer.fire();".
In my configuration Sensing.nc,3 timers are configured like following:
 
 //timer
 MSPSensingM.LedsTimer -> TimerC.Timer[unique("MSPSensing")];
 MSPSensingM.SyncTimer -> TimerC.Timer[unique("MSPSensing")];
 MSPSensingM.SendTimer -> TimerC.Timer[unique("MSPSensing")];
 
in my Stdcontrol part of  SensingM.nc, i don't fire any timer:

 command result_t StdControl.init() {
  call Leds.init();
  call PIRControl.init();
  ....
  return SUCCESS;
 }


 command result_t StdControl.start() {
  call PIRControl.start();
  return SUCCESS;
 }


 command result_t StdControl.stop() {
  call PIRControl.stop();
  return SUCCESS;
 }

 
and if i want to start the sampling,  i will send a message to nodes .The receive code is like following:
.....
event TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr message) {
 if(message->type==0x0c){//reset mote msg
   if(message->data[0] == ALL_MOTES||message->data[0] == TOS_LOCAL_ADDRESS){
  if(message->data[1] == MSG_START) {
            call SyncTimer.start(TIMER_REPEAT,timeSlot);
.....
 
But how strange it is!!  The sampling start up when i turn on the node's switch!! And sampling data is sent back!!
 
Who could tell me that is why??
