address to NV, and use this address as the MAC address later.

4) If nothing is found in 3), a 64-bit variable is randomly generated and written to the NV as the MAC address.

How can I prevent a node from continuously searching the network or increase the interval between

sending Beacon Requests?

End Device is a low-power device, battery supplied. After the node is disconnected, how can the node be

prevented from continuously searching the network or increase the interval between sending Beacon

Requests?

1)Start to search network uint8 ZDApp_StartJoiningCycle( void )

Stop to search network uint8 ZDApp_StopJoiningCycle( void )

2) Change interval of sending Beacon Request

Modify variant zgDefaultStartingScanDuration

How to make the End Device enter the low power state, how is the sleep time set?

After enabling POWER_SAVING in the protocol stack macro definition, and then make

-DRFD_RCVC_ALWAYS_ON=FALSE in the f8wConfig.cfg file, the End Device can be put to sleep.

The time to sleep is determined by the scheduling of the OSAL operating system. Each sleep time is based on

an event timeout that occurs most recently as the sleep time. Specifically, it is described in the protocol stack

hal_sleep function.

This timeout is mainly divided into two categories, one is the timeout of the application layer event, and the

other is the timeout of the MAC layer event.

1) The timeout time of the application layer is obtained by osal_next_timeout() in the

osal_pwrmgr_powerconserve(void) function.

2) The timeout time of the MAC layer is obtained by MAC_PwrNextTimeout(); in the halSleep( uint16

osal_timeout ) function.
