Hi to all,
We are managing an AMI project and we designed with our provider an external modem than can connect to different existing meters, including elster A1800. The modem is powered with external 220v source and connected to the elster meter through the rs485 port. The meter has been configured to enable the connection with the modem and the dlms protocol has been activated also to support data collection from our HES.

Hi, Mikko

1. In getCompactArrayItem() use only gxfree(value); but i think need use:
var_clear(value);
gxfree(value);

like in function getCompactArrayItem2().

2. In getCompactArrayItem2():
if (tmp->Arr == NULL)
{
//here need gxfree(tmp); because in row 1637: dlmsVARIANT* tmp = gxmalloc(sizeof(dlmsVARIANT));
return DLMS_ERROR_CODE_OUTOFMEMORY;
}

Please, check it.

Thanks!

Hi, Mikko!

In CGXDLMSProfileGeneric::setValue() in else if (e.getIndex()== 3) calls m_CaptureObjects.clear(); but there is no memory release, like in the destructor.
After m_CaptureObjects.clear(); in the loop, calls AddCaptureObject(), where it calls the new operator: CGXDLMSCaptureObject* pCO = new CGXDLMSCaptureObject(attributeIndex, dataIndex);

Thanks!

Hi Team ,

I am planning to implement the DLMS protocol in Python using the Gurux-DLMS library. I have a few questions regarding how data is transmitted through the gateway, how connections are established and maintained, and how communication happens with the meter.

We have gateways in place, and I would like to understand what type of gateways are supported by DLMS meters. Additionally, I want to know the communication media involved (similar to Modbus TCP/IP) and the complete end-to-end flow.

Specifically, I am looking for clarity on:

Hello,
I'am trying to read multiple objects with 1 query via tcp/ip using python.

Running this code:

obj1 = GXDLMSRegister()
obj1.shortName = 39656
obj1.attributeIndex = 2

obj2 = GXDLMSRegister()
obj2.shortName = 39800
obj2.attributeIndex = 2

objects = [obj1, obj2]

packets = client.readList(objects)

I am using the Gurux DLMS pyton client inside a Kubernetes pod to connect to a DLMS meter using HLS SHA256 authentication.

The client is able to successfully establish a connection and read data from the meter under normal conditions.

However, I am facing an issue after the Kubernetes pod restarts:

Once the pod restarts, the client tries to reconnect to the meter.
The connection attempt fails consistently.
The error I receive is:
"Failed to receive reply from the device in given time."

Dear Gurux Team,

I am facing a DLMS communication issue while connecting to an L&T energy meter using a USB probe and GXDLMSDirector.

I consistently receive the following error:
"Failed to receive reply from the device in given time."

Please find the details below:

Setup:

After upgrading the Gurux.DLMS Nuget package from version 9.0.2508.2201 to 9.0.2603.3001, we get the error in the subject, when trying to read association view. I have tested this on EMH and LG E850 meters, but it might be an error that affects all metertypes.

ReadDataBlock(Client!.GetObjectsRequest(), reply);
Client.ParseObjects(reply.Data, false); <--- This throws the error.

Client is a GXDLMSSecureClient object.

Hi Mikko!
In var_getInt32() calls var_clear(data); and set to DLMS_DATA_TYPE_NONE to variant type. therefore *value = 0;

Please check it.

Thanks!
