Hi @NgocHoangNguyen,
Please help me look through the ZigBee Cluster Library User Guide under Reading Attributes & Attribute Reporting.
You can utilize eZCL_SendReadAttributesRequest() to sumbit a request on a remote node, or eZCL_ReadLocalAttributeValue() to read individual attributes on a local node.
The ‘read attributes’ requests and responses arrive at their destinations as data messages. You can look into Read Events in Chapter 3, under "Read Events".
Alternatively, the server can issue unsolicited attribute reports to the client using the ‘attribute reporting’ feature (in which case there is no need for the client to request attribute values). It can be trigger either by user application or automatically.
An attribute report for all reportable attributes on the server can be issued directly by the server application using the function eZCL_ReportAllAttributes(). Please help me looking into Appendix B.4 "Receiving Attribute Reports"
Best regards, Julián
