Hi Philip, thanks for the hint, it worked so far, my timer starts now periodically. But, unfortunately, there is another problem occured.
Let me explain briefly the scenario: My tmote sky should send not in a fixed timer interval, it should send in a random interval. Thats everything I want. Therefore, I wrote this in die AMControl.startDone() call report_timer.startPeriodic( call Random.rand16() % TIMER_PERIOD_REPORT); My timer is the report_timer and TIMER_PERIOD_REPORT is defined as an uint_16 in my header file. This should initialize the timer with a random value (this works so far). Now, when the report_timer fires, I want to compute a new random value and set the report_timer period to the new value. Therefore I wrote in the report_timer.fired() call report_timer.startPeriodic( call Random.rand16() % TIMER_PERIOD_REPORT ); I thjink this should be right, or? The problem is, that the mote stops to send reports after a while (sometimes after 10 packets, sometimes after 300 packets) and I don't have any idea why?! Do you have an idea?
