Hi,
I am going to read active energy from a meter. As I am working based on logical name referencing, So I found that I need a LN constructor of CGXDLMSObject class as the input of GXClient::Read function. But I do not know how to set ln variable for CGXDLMSObject(). Could you help me?
Generally, how can I get normal request for active energy and then decode the response?
Thanks in advance.

I used below source, however it sends zero to the meter instead of OBIS code.
char *cstr1 = "0101010800FF";
basic_string <char> str1 (cstr1, sizeof(cstr1));
CGXDLMSObject pObject(OBJECT_TYPE_REGISTER, str1);
comm.Read(&pObject, 2, value);

Hi,

You should give OBIS code as dot notation.
Something like:
"1.1.1.8.0.255"

Hi,

Thank you for your kind response.
I changed my code as below, but the meter yet sends zero as Instance Id.
Could you help me? What's wrong with my source code?
char *cstr1 = "1.1.1.8.0.255";
basic_string <char> str1 (cstr1, sizeof(cstr1));
CGXDLMSObject pObject(OBJECT_TYPE_REGISTER, str1);
comm.Read(&pObject, 2, value);

Best regards,

Hi again,

I changed the code as below:

CGXDLMSObject pObject(OBJECT_TYPE_REGISTER, "1.1.1.8.0.255");
comm.Read(&pObject, 2, value);

and then I got the result.

Thank you.
