How to read/write attribute structured?

There is ZCL_DATATYPE_ARRAY and ZCL_DATATYPE_STRUCT which you can use one of them.

Thanks for your reply!
Now the data type of my attribute is ZCL_DATATYPE_ARRAY. Then which command should I send out to read attribute?
In my view, Read Attributes Command can NOT read array.
Could you show sample code for reading attribute of structure array?
Thanks.

You can use zcl_SendRead command to do it.

Do you mean that zcl_SendRead command can read one of elements of array?
According to ZCL spec, Read Attributes Command can NOT read one of elements in array.
Could you share some sample code about reading one element in array by zcl_SendRead command?
Thanks.

Do you mean to only read some bytes or single byte in an attribute array?

One attribute is structure array. I need synchronize this array between coordintor and end device.
For example, when coordintor updated the 9th element, coordintor should send the 9th element to end device.
On the other hand, if end device updated the 90th element, end device should send the 90th element to coordintor.
Thanks.

Thanks for your timely reply!
