Hi Mikko,
I am getting error "Object reference not set to an instance of an object" in 4th pass of Authentication while using HighECDSA .
Attaching logs and configuration for your reference.
Please suggest!

Hi ,
I am trying to communicate with server using Authentication and encryption with static unified model key agreement scheme .
I am Able to establish association but not able to download objects. (Attaching error snip and configuration )

Authentication logs are as below :

I need to read these parameters Set RTC, Load Limit Reset,MDI Reset,Set Interval for the Load Profile,Set Interval for the Billing Profile,DIP Request,Load Limit Enable,Load Limit Disable using dlms python library.
Passing Obis code through the example.py file or create a new code like disconnection control?

Hi,

I need to store historical data in my meter with profile generics. I can read for now current values in profiles but, once read, the data is not stored so it can be read later again. The problem is that my micro does not support files and I don't have an EEPROM. I am using a STM32 microcontroller.

How can I do this without files or EEPROM?
Is there any examples for ANSI C that implement this alternative way?

Thanks,
BR.

I have a doubt about this dlms library.If I install this library using pip install gurux-dlms how I fetch the values. Now I am downloaded from github and directly running the main.py in the example folder.And also what is the usage of push ,client example in this library.I never saw any documentation about this library.I am creating an application and want to integrate this library like normal library.How will I do that?

Hello there,

Hope this question finds you well, I am a software engineer and I am currently working on a headend project. I am having trouble understanding the purpose of the GXSynchronousMediaBase class in the media classes like GXSerial, GXNet, and GXMqtt. I saw the javadoc but the information it provides is not enough.

Thank you in advance,
sincerely,

For remote disconnect/reconnect how will we pass the obis code with attribute index when I pass 1&2 as attribute index it is returning logical name and output state. Any one have idea about that and I am using python library.

when I am passing obis code and the output will be getting after around 10 seconds.Is there any way to optimise this gurux dlms library?

Hi.

I am able to get all the values of my smart-meter using the C++ client and development from github when I execute with general parameters.
But when I am executing with parameter -g with Attribute index value 2
Note: This index value contains DataType of "object" with data for "Block load profile".
i.e., -g (blockloadProfileAddress):(indexValue)

FYI: -g (blockloadProfileAddress):Attribute Index works well if type is not object.

Hi

I am trying to access a Kaifa MA309M meter and with no communication interface provided, I am getting TimeoutException: Failed to receive reply from the device in given time.

But when I am setting the Communication interface as WRAPPER, I am getting some values that I am unable to decode can you help, the options that I am trying are

java -jar gurux.dlms.client.example.java-0.0.1-SNAPSHOT.jar -h <MeterIP> -p 4059 -t Verbose -r ln -c 16 -n "<last 6 digits of meter>" -i WRAPPER -g "0.0.1.0.0.255:1; 0.0.1.0.0.255:2"
