Hi,

Have followed ANSI C Client Example to read single object. But getting segmentation fault.
Please help.
gxData myobject;
cosem_init(&myobject.base,DLMS_OBJECT_TYPE_DATA,"0.0.96.1.0.255");
com_read(&con, &myobject.base, 2);
obj_toString(&myobject, &data); //Segmentation fault at this line

Below is the trace
TX: 7E A0 19 03 41 54 0A BB E6 E6 00 C0 01 81 00 01 00 00 60 01 00 FF 02 00 8C 6D 7E
RX: 7E A0 1A 41 03 74 DD 79 E6 E7 00 C4 01 81 00 09 08 39 30 38 33 34 35 31 37 E0 D6 7E

Thanks

Hi,

This is now tested with several different PCs without problems.
Have you set data to NULL?

char* data = NULL;
gxData myobject;
cosem_init(BASE(myobject), DLMS_OBJECT_TYPE_DATA, "0.0.96.1.0.255");
com_read(connection, BASE(myobject), 2);
obj_toString(BASE(myobject), &data);
printf("%s\r\n", data);

If you have still problems let me know the compiler and environment that you are using.
Make sure that you have the latest version.

BR,
Mikko
