Some time end device CC2538 don't enter deep sleep(PM3)

Other Parts Discussed in Thread: CC2538, Z-STACK

Hi every body, I am working on ZigBee project for 3 months. And now, I has gotten a problem some time CC2538 don't deep sleep.

I learn function halSleep of file hal_sleep.c in Z-Stack and check halPwrMgtMode = (timeout == 0) ? HAL_SLEEP_DEEP : HAL_SLEEP_TIMER;

I think CC2538 some time don't enter deep sleep (PM3) when End device joining network . In case end device can enter sleep timer (PM2).

I configured two parameter again:

#define DEFAULT_APS_DUP_REJ_TIMEOUT_INCREMENT 100

#define DEFAULT_APS_DUP_REJ_TIMEOUT 1

- I enable Power Saving in Z-Stack and disable NLME_SetPollRate .Only one polling when CC2538 wake up.

//NLME_SetPollRate ( SE_DEVICE_POLL_RATE );

If this is my mistake, how can i resolve this problem ?

Thank you for reading.

If I am not wrong, Z-Stack only enter PM2 when enable POWER_SAVING. Why do you think it would go PM3?

Hi YK Chen .
I configured Z_Stack of CC2538 enter deep sleep (PM3) successfully. But I have problem, Some time CC2538 doesn't enter deep sleep (PM3).
I set parameter below :
- set Power saving
- Disable call function "NLME_SetPollRate ( 0 );" Only one polling request data from gate way when CC2538 wake up by interrupt external GPIO call function "NLME_SetPollRate ( 1 );"
- Disable function "NWK_AUTO_POLL" in my workspace.
Thanks

How and when do you make device enter PM3?

Hi YK Chen ,
I set up CC2538 enter deep sleep When CC2538 is initial successful and send data to gate way completely . CC2538 was waked up by interrupt external GPIO occur.
In my project use PIC so control CC2538 wake up by Interrupt GPIO according period.
Thanks

You said sometimes it doesn't work. Why do you judge it doesn't wake up? Is it possible that CC2538 wakes up but you are not aware of it.

Some time CC2538 doesn't enter Deep sleep (PM3) after CC2538 joining network ZigBee . In case i think CC2538 enter sleep timer (PM2 ).
Thanks

How do you judge CC2638 enters PM2 not PM3?

I measure consumption current of CC2538 in every case.
Consumption in PM2 is lost more power in PM3 .

In file hal_sleep.c have line of code halPwrMgtMode = (timeout == 0) ? HAL_SLEEP_DEEP : HAL_SLEEP_TIMER; So detect CC2538 enter mode sleep ?
In case CC2538 deep sleep , I set gpio of CC2538 which caution for PIC is CC2538 prepare enter deep sleep before CC2538 enter deep sleep .

I sure CC2538 enter deep sleep (PM3). But Some time CC2538 enter sleep time (PM2).

Thanks so much!

Hoang Huan.

Z-Stack only make CC2538 goes to PM2 not PM3. If you want to enter PM3, you have to write register for that by yourself.

To add to YK's answer, the difference in current draw when the chip is in PM2 and PM3 is ~1uA, are you really able to see the difference?
