Read the value of an OBIS code

Hi,

I am using below functions to get the value of Active Power:

CGXDLMSVariant value;
CGXDLMSObject pObject(OBJECT_TYPE_REGISTER, "1.1.1.8.0.255");
comm.Read(&pObject, 2, value);
long unsigned int IntValue = value.ToDouble();

But value variable in CGXCommunication::Read function returns nothing. (The value variable in not used in the function.
This way worked with the previews version written without Linux OS option.

could you help me how to read an active power value?!

Best regards,
Leila

Hi,

I solved the problem by making below changes in the source codes:
1. In GuruxDLMSClientExample.cpp file, in main function, after initializing, I added:

CGXDLMSVariant value;
CGXReplyData reply;
CGXDLMSObject pObject(OBJECT_TYPE_REGISTER, "1.1.1.8.0.255");
comm.Read(&pObject, 2, reply);
value = reply.GetValue();
printf("Register value is:(int) %d\n", value.iVal);

2. In CGXCommunication::Read function, I modified the function inputs:

int CGXCommunication::Read(CGXDLMSObject* pObject, int attributeIndex, /*CGXDLMSVariant& value*/CGXReplyData& reply)

3. In CGXCommunication::Read function, I commented:

//value.Clear();
//CGXReplyData reply;

4. In CGXCommunication::UpdateAccess function, I commented all except:

return ERROR_CODES_OK;

The number four change is not a efficient way, but it helps the software to work.

Could you help me how to solve the problem more efficiently?

Best regards,
