CC2538: Sleep mode and reports

Other Parts Discussed in Thread: Z-STACK,

Hello,

I have been working on an application code base on the sampleLight example from Z-Stack Home 1.2.2a.44539. At first I tried putting my ZED to sleep by enabling the POWER SAVING flag in the compiler option but that never seemed to put the device to sleep. So I decided to do it on my own. I set an event to make the device sleep every 30 seconds for 1 minute (the durations used are for testing purposes) and the code is like this. My problem is that the reports to the router are often not send and I am not sure why. The reports are set to fire up every 60 seconds. What could be the issue for it ? Am I omitting something ?

if(events & MEAZON_MISC_WATER_SLEEP_TIMEOUT_EVT)
    {
      if ( MAC_PwrOffReq(MAC_PWR_SLEEP_DEEP) == MAC_SUCCESS )
      {    
        ui32Val = SleepModeTimerCountGet();
        SleepModeTimerCompareSet(ui32Val + 274285);
        
        HAL_TURN_OFF_NWK_LED();
        
        SysCtrlDeepSleep();

        /* Update the osal timers and clock with the sleep time */
        osalAdjustTimer(60000);
        
        MAC_PwrOnReq();
        
      }
      
      osal_start_timerEx( meazonMiscTaskID, MEAZON_MISC_WATER_SLEEP_TIMEOUT_EVT, 30000 );
      
      return ( events ^ MEAZON_MISC_WATER_SLEEP_TIMEOUT_EVT );
}

Thank you for your time

After defining POWER SAVING in your ZED project, the ZED would enter sleep mode automatically and you don't have to do any extra event to make sleeping happen. Anyway, where and how do you do report every 60 seconds?

I know that but in the modified code i was given this doesnt seem to work. To report I have a zigbee event that fires up every one second and checks if it's time for a report to be send.

1. For POWER_SAVING, you can enable HAL_SLEEP_DEBUG_LED in halSleep() to debug if CC2538 enter sleeping mode.

2. Maybe add a LED to indicate/debug if the one second event in your code fires the report.

Thanks for the advice. I will test my code with them.
