Re: [Tinyos-help] help, strange automatic fired timer!!

I think that it's exactly the other way around. You have to use the same string in very instance so that the compiler knows that they must have different numeric values. At least, that's what I understand from the documentation [1].

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??
