Our AMR has to be able to reconfigure the display configuration of an specific meter. To do that, it is necessary to perform a write attribute operation, changing an attr that is of type 'array'. Each position of this array represents one of the screens to be displayed by the meter, so the more screens are needed, the longer the array needs to be.

In the case, we are using Gurux DLMC for C to perform the DLMS operations.

Hi,
Tell me, please, I launched the simulator with a template, in which there is object ProfileGeneric with data. I'm trying to read data from this object - it returns an empty array.
And second, is it possible to make object 1 dynamically filled with data every day that can be read?

Thank you!

Hi

On the method HandleAarqRequest you are checking if MaxAPDUSize is lower than 64 and return an error PduSizeTooShort.
Maybe it will be great if MaxAPDUSize comes to 0 change it to the max value allowed, i think is 65365.

Thanks

Hello,

if I have a cascade of meters sharing a common gateway or communication device (IP), is it possible to read out these different devices within the same IP connection or has a separate connection to be made for every device?

I want to push value with mqtt.
With this I can read meter and push to mqtt:

//Read active power 1.8.1
gxRegister rdn1;
cosem_init(BASE(rdn1), DLMS_OBJECT_TYPE_REGISTER, "1.0.1.8.1.255");
com_read(BASE(rdn1), 2);
obj_toString(BASE(rdn1), &data);
GXTRACE(GET_STR_FROM_EEPROM("Active1"), data);
client.publish(topic, data);
obj_clear(BASE(rdn1));
free(data);

How can I get value only like: 8560182 without: Index: 3 Value: Scaler: 1 Unit: None
Index: 2 Value: 8560182?

GXDLMSObject writeData = item.GXDLMSObject;
GXDLMSObject readData;
if (writeData is not null)
{
readData = writeData.Clone();
}
When cloning to readData, the error "System.ArgumentNullException: "Value cannot be null. Arg_ParamName_Name", although writeData is not null.
The same situation when using the CopyTo() method;

Hello! I am trying to reset buffer of time correction journal by this code:
time_correction_journal = GXDLMSProfileGeneric("0.0.99.98.13.255")
reader.readDataBlock(time_correction_journal.reset(settings.client), GXReplyData())
I connected to the meter with High authentication, my client address is 48. Nevertheless I am getting error: gurux_dlms.GXDLMSException.GXDLMSException: Access Error : Device reports Read-Write denied. How can I solve it?
Thanks for help!
