how to realize the low-power consumption？

i want to know how to realize the low-power consumption？

for example，i want the enddevice to collect temperature information every 10 second，so during the period，i can make the enddevice to sleep，what should i do，could you give me some help？

Hi,

You should define POWER_SAVING and set POLL_RATE to a longer period in the project settings. In my experience, the power consumption is lower than 20 uA.

hi，

thank you for your reply， i am confused by the low-power consumption.

i have enabled the POWER_SAVING, however, i don't know the meaning of POLL_RATE, and so i don't know set the POLL_RATE to what value, 50 or 100？could you show me some details?

what's more，there some compile options，like

NWK_AUTO_POLL
ZTOOL_P1
MT_TASK
MT_SYS_FUNC
MT_ZDO_FUNC
xLCD_SUPPORTED=DEBUG
POWER_SAVING

could i disable all the MT_ headed compile options，because i don't use the MT funtions，could you give me some help/

thanks very much,

best regards,

Hi,

POLL_RATE means the period that an end device wakes up and polls from it parent node to see if its parent has any message for it. I suggest you can set it to 2 seconds and it should be enough for power saving. For ZTOOL_P1/MT_TASK/MT_SYS_FUNC/MT_ZDO_FUNC, you definitely can disable them since you don's use them. These definitions are nothing to do with power consumption but code size.
