Accessing profile generics on EDMI Mk7MI

Hi Mikko, thank you for the rapid response. I did check the GXDLMSDirector first before developing the client app, and there is a row of data.
After modifying the code, there's some content inside Index 3. Below is the modified code, kindly check the code.

int com_readPg()
{
int ret;
int len, month = 0, day = 0, year = 0, hour = 0, minute = 0, second = 0, value = 0;

ret = com_initializeConnection();
if (ret != DLMS_ERROR_CODE_OK)
{
GXTRACE_INT(GET_STR_FROM_EEPROM("com_initializeConnection failed"), ret);
return ret;
}
GXTRACE_INT(GET_STR_FROM_EEPROM("com_initializeConnection SUCCEEDED"), ret);
GXTRACE_INT(GET_STR_FROM_EEPROM("\n"), ret);

char *data = NULL;
gxProfileGeneric pg;
cosem_init(BASE(pg), DLMS_OBJECT_TYPE_PROFILE_GENERIC, "1.0.99.1.0.255");
com_read(BASE(pg), 3);
com_read(BASE(pg), 2);

// by range
gxtime start1, end1;
time_init(&start1,2023,1,1,00,00,00,0000,0);
time_init(&end1,2023,1,2,00,00,00,0000,0);
com_readRowsByRange (&pg, &start1, &end1);
obj_toString(BASE(pg), &data);
// obj_toString(pg.buffer, &data);
GXTRACE(PSTR("Load profile (range) : "), data);
obj_clear(BASE(pg));
free(data);

// Release dynamically allocated objects.
Client.ReleaseObjects();
com_close();
return ret;
}

At first there are bunch of data send failures, after that there is some content in Index 3, I assume these are the registers which is used for this profile, is that correct? Take a look at the output:

0 :Data send failed. Try to resend. 1 :Received bytes:
0 :Data send failed. Try to resend. 1 :com_initializeConnection SUCCEEDED 0 :

Index: 4 Value: 0
Index: 5 Value: 0
Index: 6 Value:
Index: 7 Value: 0
Index: 8 Value: 0

After some tinkering, i found that commenting
com_readRowsByRange (&pg, &start1, &end1);
will give the same output (bunch of failure, then read Index 2 to Index 8 with Index 3 having some content), and there is also failure in executing the code (see below)
:com_readRowsByRange failed. 130
Is the code/function that i use wrong? Or is it anything else?

Thanks in advance.

Hi Mikko, I am using EDMI Mk7MI meter.
1. Where can I get information about time deviation of a country?
2. What are the settings I should check so I could adjust the settings to match the meter? Since we don't get the document for reference
3. I once had success reading the profile using index (read index = 1, Count = 1), can I use that method instead? Do you have code that can achieve this in C/Arduino code?

I use below code to read by index entry, but no success. Please take a look.
//=============================================
// by entry
com_readRowsByEntry(&pg, 1, 1);
// com_readValues();
// com_readProfileGenericColumns();
// com_readProfileGenerics();
obj_toString(BASE(pg),&data);
// GXTRACE(GET_STR_FROM_EEPROM("Profile register : \n"),data);
Serial.printf("Load profile (entry) : ", &data);
obj_clear(BASE(pg));
free(data);

Thanks in advance.

Hi Mikko, thank you for the guidance, after I add
com_readProfileGenericColumns()
the values showed. Here are the output, it still give some "data send failed" message :
0 :Data send failed. Try to resend. 1 :Received bytes:

1. If i understand correctly, the values shown are the value of pg of gxProfileGeneric, is it right?
2. How to print just the content of index 2, as it is what I needed?
3. If I want to save it to a struct so I can use it for another thing, how to accomplish this? For the register data, first I created this struct :

struct dataCollection
{
uint32_t timeUnix;
String serialnumber;
float volt;
float current;
float watt;
float battery;
}
Then i use this to read the register data (again for example I'm going to access voltage value)
gxRegister volt;
cosem_init(BASE(volt), DLMS_OBJECT_TYPE_REGISTER, "1.0.32.7.0.255");
com_read(BASE(volt), 3);
com_read(BASE(volt), 2);
obj_toString(BASE(volt), &data);
datameter.volt = var_toDouble(&volt.value) * pow(10, volt.scaler);
Serial.printf("Volt : %.3f\n", datameter.volt);
obj_clear(BASE(volt));
free(data);

Using gxRegister I can just access the value via volt.value, but in gxProfileGeneric there isn't, so I can't get the data.
It doesn't have to be a struct though, I use it because I think it is simpler. An example of code in C would be greatly appreciated.

Again, thank you for the help and guidance

Hi, Mikko, I tried using the example you provided, but it give me Guru Meditation Error : Core 1 panic'ed (StoreProhibited).Here's the code I use

gxProfileGeneric *pg;
gxByteBuffer ba;
gxtime start1, end1;
time_init(&start1,2023,1,1,00,00,00,0000,0);
time_init(&end1,2023,12,1,00,00,00,0000,0);
cosem_init((gxObject*) pg, DLMS_OBJECT_TYPE_PROFILE_GENERIC, "1.0.98.1.0.255");

Serial.println("READ PROFILE INDEX 3");
com_read((gxObject *)pg, 3);

Serial.println("READ PROFILE INDEX 2");
com_read((gxObject *)pg, 2);

com_readProfileGenericColumns();
com_readRowsByEntry(pg, 1,10);

// com_readRowsByRange(&pg, &start1, &end1);

ret = obj_toString((gxObject*)pg,&data);
if (data != NULL)
{
bb_Init(&ba);
obj_rowsToString(&ba, &pg->buffer);
data = bb_toString(&ba);
printf("%s", data);
free(data);
data = NULL;
}

obj_clear((gxObject*)pg);

Client.ReleaseObjects();
com_close();
return ret;
