Hi Kurumi,

I am trying to write data in value attribute in register object and load using Serializer_Save and Serializer_Load. But I am facing issue with writing the data. Using GXDLMSDirectore when write some data and click on WRITE button, 0 is reflecting and in ESP32 server code, reference value is not reflecting the same. Its always 0.

Hi, Mikko!

I have CGXDLMSVariant with octet string value date-time. Ho to convert it to CGXDateTime?
Is it possible to add function (or constructor) to CGXDateTime class for convert from/to CGXByteBuffer?

Thanks!

The device returns the correct value 522140, but after multiplying by scaler 0.01, returned the value 5221.40000000000005.

This does not happen with all data.

Below is a screenshot showing the code of file "GXDLMSProfileGeneric" with incorrect data conversion.

Please tell me, can this be fixed?

Thanks.

Hi Kurumi,

We are trying to understand what data is stored about the objects which we create using example

Hi!

When communicating with a meter through a gateway, there is a  GXDLMSException("Invalid reply. The client has closed the connection.") thrown for a successful ReleaseResponse wrapped in GatewayResponse.

I believe the reason is that this peace of code doesn't recognize it: https://github.com/Gurux/Gurux.DLMS.Net/blob/5284708bd1b9823d9d9f817223dc2f5993deeb02/Development/GXDLMS.cs#L5658-L5665

Example packet: 

I have implemented a Python script to read the Header and scaler values sent from the meter through the Wrapper interface using GXDLMSReader. Similarly, I want to have a function to read a Header and Scaler from a fragmented HDLC frame. Please let me know how I can achieve this.
Note: My current implementation always returns "Invalid HDLC frame," but the frame is being translated correctly in the Gurux online translator.

hello,
below code is for to read instantaneous and billing profile - - >

void
read_meter_instantaneous_profile()
{
gxProfileGeneric profile;
char * data = NULL;
cosem_init(&profile.base, DLMS_OBJECT_TYPE_PROFILE_GENERIC, "1.0.94.91.0.255");

com_read(&profile.base, 2);

/* Read rows by entry */
com_readRowsByEntry(&profile, 1, 2);

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
Plamen

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
