The zigbee BDB has included reporting system. But sometimes reporting is triggered at the moment of attribute changed. If a broadcast command or scene-control command is sent to multi zigbee devices, zigbee devices will report their changed attribute. At this moment, MAC-CSMA is unable to send successful. So I suggest that once BDB reporting is triggered, user-app could capture the reported message and record it. Once reporting is sent failed, user-app should have chance to retry after a longer waiting.
