Beestack & PWR_EnterLowPower - DEEPSLEEP

roby — Tue, 17 Apr 2007 00:12:51 GMT

Hi All,
I am working on the Beestack and freescale SARD modules. I enabled the Power Libs on the End Device (ED) and I am tring to take it in --> DeepSleep Mode. The PWR_EnterLowPower function checks for any pending timer and allows the ED to go sleep in DEEPSLEEP mode only if there are no active timers!
Unfortunatly I noticed that 1 timer not expires so I am not able to enter the DeepSleep mode ( but only the PWR_Sleep) !I tried to Stop all timer unnecessary but I am not able to find the active timer. I think it is a repeating timer allocated by the TMR_StartIntervalTimer() function...but what??Does anyone can help me??

Thank in advance...

Hi all,
I solved the Deep Sleep problem. Unknowingly during some tests, I set the End Device Intervall Poll to a non-zero value into the BeeKit and I exported the properties...Afterwards I forgot to restore the value to zero!
For your information I noticed Beestack contains the following code

#ifdef gLpmIncluded_d
#if gLpmIncluded_d
   #ifdef mDefaultValueOfPollTimeOut_c
     #undef mDefaultValueOfPollTimeOut_c
   #endif

   #define mDefaultValueOfPollTimeOut_c 0x00000000
#endif
#endif

and this get me sidetracked! Probably the code above does not avoid the Beestack start a TMR_StartIntervalTimer...which remains active and does not allows the End Device to enter in DEEP SLEEP mode!

Bye
Roberto

Hi Roberto,

I'm starting to use the Pwr module but i have a problem, when the device goes in deep sleep mode it never come back... I have try to set different value for cPWR_RTITickTime and cPWR_RTITicks without success.
Do you have any suggestion to me?
