Detailed Description

Power Saving for ZED

For sleepy end devices (RxOffWhenIdle = TRUE), ZBOSS provides a mechanism for power saving. ZBOSS scheduler tracks the callback queue and if there is no immediate callback for execution and there is no outgoing packet on the MAC level, a special signal ZB_COMMON_SIGNAL_CAN_SLEEP is sent for an application. The "can sleep" signal has a sleep time parameter that indicates allowed sleep duration in milliseconds.

Sleep duration value is based on the time remaining before the first alarm is called or it is set to 10 seconds if there are no alarms in the queue. Upon receiving ZB_COMMON_SIGNAL_CAN_SLEEP the application analyzes its internal state and decides whether to enter the sleep mode or not. To go to the sleep mode, the application should call the zb_sleep_now() function.
