MC13224V - Beestack - Battery operated end-devices don't hibernate if ZigBee network is down (electrical power outage)

in home automation application I have a coordinator, a few routers and 1 or 2 end-devices. The coordinator and the routers have their own power supply connected to the house 110Vac. The end-devices are battery operated and need to hibernate periodically to save battery.


In case of electrical power outage (110Vac) the coordinator and all routers go down. The end-devices keep running since they have its own battery. When the outage happens, the end-devices lose their parent and start to look for a new parent. Since there is no active coordinator or router in the ZigBee network the end-devices keep continually looking for a parent and never hibernate, discharging the battery completely in a few hours.


What should I do to force the end-devices to hibernate in such situation? In my application, I'd like to hibernate for 1 minute, wake-up and look for a parent. If there's still no active parent hibernate for 1 minute again. And keep doing it every minute until the electrical power (110Vac) return.


I tried to change the value of the following constants (in ApplicationConf.h) with no success. I can control the number of network rejoin retries but I can't hibernate the MC13224V between attempts.
