[ZIGBEE] switch key procedure

SDK: 4.1.0

CHIP: 52840

old question

my sleepy zed lost connection to the coordinator after refreshing key of the coordinator.

1) how can I manipulate refresh key of the coordinator?

2) how can I callback to receive broadcast packet?

3) Is there rejoin request function without security? the coordinator manufacturer says that the plain request of rejoin must be procedured after switching key.

4) how can I callback to receive APS packet?

the zed received "switch key packet" but doesn't procedure anything.
