OMNeT++ 4.3 and MiXiM 2.3 Strange Behaviour The timers from IEEE 802.15.4 Narrow seems to disappear

[Norberto_IT]

I have found a strange behaviour in the MiXiM 4.3 Simulator.

I have a timer responsible for putting the radio in the Sleep Mode. After some time I wakeup the Radio again.

else if(msg==scheduleWakeUpTimer){         //_(NB)_Schedule Next Wake-up Time (2013-06-04)

        EV<<endl<<"\t** (NB) msg==scheduleWakeUpTimer"<<endl;

        EV<<"\t** (NB) phy->getRadioState(): "<<phy->getRadioState()<<endl;

        if(phy->getRadioState()==MiximRadio::SLEEP)

            phy->setRadioState(MiximRadio::RX);

        if(!manageQueueTimer->isScheduled())

            scheduleAt(simTime()+DT, manageQueueTimer); //_(NB)_Since all the nodes wake-up at the same time this avoids a collision

        //_(NB)_This code used for the duty cycle (2013-06-04)

        cancelEvent(scheduleWakeUpTimer);                           //_(NB)_If the event scheduleWakeUpTimer already exists cancel before schedule a new one (2013-06-04)

        scheduleAt(simTime()+frameLength, scheduleWakeUpTimer);     //_(NB)_The node will wake up after frameLength (2013-06-04)

    }

By using the normal IEEE 802.15.4 Narrow procedure after manageQueueTimer  I enter in the backoffTimer and I got the following error:

Simulation terminated with exit code: -1073741819

However If I create a new  ccaTimer inside the backoffTimer the error disappears.

if(msg==backoffTimer){

        ccaTimer->getCreationTime();

        EV<<"\t** (NB) ccaTimer->getCreationTime(): "<<ccaTimer->getCreationTime()<<endl;

            ccaTimer = new cMessage("timer-cca");

        EV<<"\t** (NB) macQueue.size(): "<<macQueue.size()<<endl;

        executeMac(EV_TIMER_BACKOFF, msg);

}

Can someone explain to me what is happening???

It seems like the timers disappear when I go to the sleep mode by using    phy->setRadioState(MiximRadio::SLEEP);
