I have some questions
I'm using one coordinator and 8 end-devices (Zigbee) for monitoring system.
When leaving work, I have to turn off the power of coordinator (it must be done because of safety).
Then, end-devices which use battery keep awake and scan their parent, so batteries are gone too fast.
1) Is there any method to prevent Zigbee end-device which is loosing parent from waking up?
2) Could I solve that problem in 802.15.4 Firmware?
If there is someone who can solve this problem, please let me know. Thanks.
AT Parameter (sleep) such as :
- SP : C8 (2 sec)
- SN : D2F0
- SM :  Cyclic sleep
- ST : 4E20 (20 sec)
