Hi, Is it possible to send and read structured attribute if it is 300-500 bytes or more using ZCL?

Basically, if you send 300-500 bytes, it would be handle by Z-Stack with ZIGBEE_FRAGMENTATION enable. However, it's not recommended to send such large packet over Zigbee.

Thanks for answer, I would like to send RGB led pattern to zigbee node, is there better way to do it? Is ZIGBEE_FRAGMENTATION works with ZNP too?

I would suggest you to breakdown the whole package into several pieces, for example 60 bytes of each, and send them one by one to the node.
