Hi Mikko,

trying to read profile generic data using WRAPPER.But unable to process the response. "Device reports a hardware fault"
Below is the code snippet and log

cl_init(&con.settings, 1, 32, 1, DLMS_AUTHENTICATION_LOW, "LWTSM", DLMS_INTERFACE_TYPE_WRAPPER);
ret = com_initializeConnection(&con);
if (ret != DLMS_ERROR_CODE_OK)
{
return ret;
}
cosem_init2(BASE(my_profile_object),DLMS_OBJECT_TYPE_PROFILE_GENERIC,"0.0.94.91.10.255");
com_read(&con, BASE(my_profile_object), 3);
com_read(&con, BASE(my_profile_object), 2);

obj_toString(BASE(my_profile_object), &data);
if(data != NULL)
{
printf("%s\r\n", data);
free(data);
data = NULL;
}
else
{
printf("Data is NULL...\n");
}

Hi,

Check your logical name. You try to read the profile generic with logical name 48.46.48.46.57.52 and it's not correct.

Hi,
we are initializing cosem with
cosem_init2(BASE(my_profile_object),DLMS_OBJECT_TYPE_PROFILE_GENERIC,"0.0.94.91.10.255");
not sure why is it sending 48.46.48.46.57.52 OBIS code?

with cosem_init(BASE(my_profile_object),DLMS_OBJECT_TYPE_PROFILE_GENERIC,"0.0.94.91.10.255");
response is received but parsing problem. attached log with debug for your reference.
data type mismatch i think

Debug has been collected from "int dlms_getData(gxByteBuffer* data, gxDataInfo* info, dlmsVARIANT* value)" function in dlms.c file

Hi,

Use it like this:
const unsigned char ln[6] = { 0, 0, 94, 91, 10, 255 };
cosem_init2(BASE(associationShortName), DLMS_OBJECT_TYPE_PROFILE_GENERIC, ln);

or:
cosem_init(BASE(my_profile_object),DLMS_OBJECT_TYPE_PROFILE_GENERIC,"0.0.94.91.10.255");

You need to read capture objects before reading buffer.
Attribute index of capture is #3.
