Good day
I am learning how to develop DLMS server. I am able to create a client app to read meter, and send it to a database. I used ESP32 to achieve that. Now I want to make a DLMS server to simulate a meter, let's say it's MyMeter. I want to combine/accumulate the data from two meters' profile generic into one profile generic that this MyMeter have. I plan to code in C or C++ for this. Is this possible? If it is, how to accomplish that?

Thanks in advance.

Hello,

I have an APDU byte array, and I'd like to convert it to GXDLMSObject so I can inspect and further work with it. I see that I can use GXDLMSTranslator to translate the byte array to XML, but I want to parse the byte array to a native GXDLMSObject. Is there any way to do that?

Many thanks

Hi, I want to create an simulator with HighGmac authentication by editing crystal.xml in gurux.sinulator project but i doesn't work. So i wanna ask how to create a simulator like that. Thank you

In Gurux GXDMS Director tool, I tried to refresh objects to read all the objects from my meter, the new objects has been added to the list, but when I try to select and read them, I receive this error:

ERROR: The given key was not present in the dictionary.

Also the new object is MBUSDIAGNOSTIC

I would be grateful if you can help me with this problem.

Hi Kurumi,

Currently working on PC association using guruxDLMSserver.c with ESP32 using Arduino IDE .
With TCP communication we are able to download objects using GXDLMSDirector. Now we want to use US association.
Unable to assign authentication key and blockcipherkey in esp32 as dlms server.
What settings we need to do or add to get US association work.

Thank you

Greetings,

Im currently using DLMS Simulator to simulate a device, but im struggling to first read the device data correctly, I firstly used the integrated read function of the simulator, the conexion is correct and I generate a .xml but I get "invalid" values from the reads:

Command: "Gurux.DLMS.Simulator.Net.exe -h (ip) -p 4059 -i WRAPPER -c 2 -s 1 -a Low -P (password) -t Verbose -o fileoutput.xml"

Starting MQTT client...
Connected to MQTT broker with result code 0
Subscribed to topics: meter/parameters, meter-id, obis-code
Received message from topic meter-id: EP1240009
Received meter-id: EP1240009
Meter ID set to: EP1240009

I am using the gurux client Sample from the github repo in the following link https://github.com/Gurux/gurux.dlms.java/tree/master/gurux.dlms.client…

I run it with provided argument I got the available meter that I have access to in XML file, but I don't how the get data received from meters and which function to use to return the data so I can store it in a json file and push it my pipelines.
anyone have an idea about that I will appreciate any help.

Hi,

I am trying to enable/disable HLS security on E360 meter from Landis. I am having troubles with how to generate correct frame for GXDLMSAssociationLogicalName object. I am trying to write "AuthenticationMechanismName" (attribute 6) to the meter but I would need to encode it not as a struct but as an octet string, could you help me with that?

This is an output frame that I am currently getting:
C104C102000F0000280002FF0600004000002B0000FF0200020207110211101202F411051108110211011600
