Hi Team,

I have to update authentication key & encryption key in smart meter. I were able to do it using gurux dlms director using update key option.

From code I was not able to do it. Below is the code snippet which i have used. Do global key transfer method does not apply key automatically. Can I please get correct code snippet to update the key

Hello

I have a gurux server based on the example 2, I'm using the python gurux library in order to query it, it works flawlessly when I'm using ipv4 but as soon as I try to query the server using ipv6 I get this error on the server side "java.io.IOException: Invalid argument (sendto failed)"
Is there something specific to be able to have a server use ipv6 ? Did I miss something ?

Hi, I just started exploring higher levels of security. At the moment I'm trying to use HLS with ECDSA.

Client is using java library and server is based on gxsimulator.

In my approach below I have only one problem with signing CSR for meter.

Hi,
I'm having trouble when reading some objects in List. Server is based on gxsimulator.
All attributes can be read alone, but when in list, I got:

class [B cannot be cast to class java.lang.Number ([B and java.lang.Number are in module java.base of loader 'bootstrap')
gurux.dlms.objects.GXDLMSDemandRegister.setValue(GXDLMSDemandRegister.java:578)
gurux.dlms.GXDLMSClient.updateValues(GXDLMSClient.java:1510)
cz.vutbr.client.reader.MyReader.readMyList(MyReader.java:839)

Hi all,

Hello!

There was a problem while I was using Gurux.java.
When running in a Linux environment, the following RX packet loss.

Hi all,

I'm relatively new to DLMS and associated development. I'm trying to build a Tridium Niagara driver for DLMS. I am using the latest JARS of all libs
gurux.dlms/4.0.24
gurux.net/1.0.21
gurux.common/1.0.17

I went through the code samples given on the page https://www.gurux.fi/Gurux.DLMS.Notify#Java, however was unable to understand where the socket open and related functionality is being implemented for listening to data/event notifications.

Hi all,

Hi,
I am facing issue with reading/writing L&T meter. After authentication, for any requests, its giving Invalid Command exception. Everything working in GXDLMSDirector.

Just for example - Relay Disconnection

GXDLMSDisconnectControl relay = new GXDLMSDisconnectControl("0.0.96.3.10.255");
byte[][] data = relay.remoteDisconnect(com.dlms);
GXReplyData reply = new GXReplyData();
com.readDataBlock(data, reply);

java.lang.IllegalArgumentException: Invalid Command.

Hi all,

I was able to run the server from https://github.com/Gurux/gurux.dlms.java/tree/master/gurux.dlms.server… , and am using the code from https://github.com/Gurux/gurux.dlms.java/tree/master/gurux.dlms.client… to read data.
