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.

Hello,
I'm trying for past few days to use keyAgreement method from SecuritySetup to agree on keys on multiple meters from different vendors.

So far all my attempts resulted in error: Other reason.

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!

Are there any example implementations of DLMS/COSEM servers that use ECDSA for High-Level Security (HLS) authentication?
