Hi *
I have a little problem with Timers. In my application I use two timers
"JobTimer" and "StopTimer". I send from base station a start signal and
start the JobTimer with some intervall( let say 1000 ). After that I
start StopTimer.startOneShot(10000). So that looks like :
// ... get start signal form BS
atomic ssBit = TRUE; // StartStopBit
call SensingControl.startSensing(1000,0); // <- starts sensing ... no
matter
startTS = call JobTimer.getNow(); // start timestamp
call JobTimer.startPeriodic(1000); // start periodic every second
call StopTimer.startOneShot(10000); // stop after 10 s
// ..................................................
// now fire events:
event void JobTimer.fired() {
if (!radioBusy && ssBit) { // if radio is free and ssBit
true
post sendMeasurement(); // send measurement to BS
}else{ // else (read if
ssBit =
false
sendResult(); // send result (other
measurement) to
BS
}
}
event void StopTimer.fired(){
atomic ssBit = FALSE; //set ssBit false
call SensingControl.stopSensing(); // stop sensing
call JobTimer.stop(); // stop JobTimer
call JobTimer.startOneShot(10); // start JobTimer once !!!
}
The problem is when i call JobTimer.startOneShot(10) it start
JobTimer.startPeriodic(10)!!! I don't understand this behaviour ?!? Is
there some study about it? Has somebody observed similary behaviour of
Timers?
cheers
