I use JN-5168 to implement sleep end device on Zigbee pro 3.0, this sleep end device will sleep 10sec and wake up (about 3sec.) to receive polling data success, that received has send from coordinator during end device sleepping, but end device can't received any more data after wake up, so how can I send long data (around 3MB or normal size 64byte) to sleep end device form coordinator side during wake up mode state and end device can be received immediately?
can you decrease ZED sleep time from 10s to 7.5s which is the maximum buffer timing by the ZED parent for temporal store the date deliver to ZED
Could you please check the JN-UG-3048? I believe that the chapter 5.5.3 Polling for Data it's a good guide to start, and you can check the whole chapter.
Also the Part IV: Appendices especially the B.2 Sending Data to Sleeping End Devices section.
