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!

Bonjour, j'ai 350 compteurs smartESOX de chez APATOR et 33 concentrateurs.
Cependant je n'arrive pas à me connecter à plusieurs compteurs sur la même adresse IP et le même port. J'ai donc crée un programme de test qui est composé de 3 compteurs qui partagent la même adresse ip et le même port.
Je réussi à me connecter au premier compteur mais les deux autres compteurs échouent au niveau de _reader.InitializeConnection(); .
Vous trouverez ci dessous le code de mon programme de test. j'utilise c#

Hello everyone,
Does anyone have a verified working wiring diagram or screenshot for the RJ11 to RS232 pinout on the Secure Premier 300 meter?
I’m specifically looking for a confirmed setup that has been tested successfully. Any reference images or pin mapping details would be greatly appreciated

Dear Gurux Team,

I hope you are doing well.

We are currently working on the development of electricity meters and are interested in implementing a DLMS/COSEM stack in our Renesas Controller. We would like to understand whether Gurux provides a DLMS stack suitable for integration into meter firmware, along with details regarding licensing, commercial usage, and technical support.

Kindly share the relevant information and documentation to help us evaluate the solution.

Looking forward to your response.

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)

for p in packets:
reply = send_and_receive(p)
client.getData(reply)

gives me an error:

hi Am trying to connect the Gurux GXDLMS Director to the landisgyr meter and it has a CU-XE communication module. There are no Obis codes in the software, and it says failed to receive reply from device. can you help? I can only connect with the MAP110 from landisgyr but with Gurux is giving me problems.
