every versions of Z-stack not support Diagnostics cluster correctly.

Other Parts Discussed in Thread: Z-STACK

In z-stack, "Diagnostics" calls "zcl_registerReadWriteCB" to register the function “zclDiagnostic_ReadWriteAttrCB” to read or write Diagnostics cluster 's Attribute. But in zcl.c, if the function has been register by “zcl_registerReadWriteCB” is wanted be called, the Attribute should be register in attribute array by “zcl_registerAttrList” with "attr->dataPtr = NULL" .

Diagnostics cluster attributes are defined in DiagsStatsTable variable of type DiagStatistics_t. When there is a read attribute command for this cluster the stack resolves automatically that zclDiagnostic_ReadWriteAttrCB() needs to be used when is registered and this callback propose is to get the attribute pointers for the read attribute response.

The reason why attr->dataPtr = NULL in zcl_registerAttrList is because the pointer for those attributes are not accessible for the application and this is the way that you tell that the pointer will be retrieved using a callback function.

Yes, as myunderstanding, if I want to use ZCL diagnostics, I should add the diagnostics cluster attributes into attribute-list of my application endpoint, to make zclDiagnostic_ReadWriteAttrCB valid.

But, in BDB_Reporting, the diagnostics cluster attributes can't be accessed by reporting because the BDB_Reporting can't access attributes that can only be accessed by ReadWriteAttrCB.

In z-stack, the attribute value of ZCL diagnostic is accessed by zclDiagnostic_ReadWriteAttrCB which has been registered by zcl_registerReadWriteCB. But in z-stack 's BDB reporting and zcl_SendReportCmd, the attribute value is accessed only by attr->dataPtr in Attribute-List except by pfnReadWirteCB. Only zcl_SendReadRsp can access correct attribute value by both attr->dataPtr and pfnReadWirteCB.

Aries Lord,

The issue is related to that. Let me test a couple of things and then generate a patch for this issue.
