For which standard version Gurux.DLMS.cpp designed for?
Readme states that it's suitable for "ANSI C++", which stands for first C++98 standard. That is good for portability and some old embedded devices, but maybe it will be good to upgrade current version(or make parallel version) of Gurux.DLMS.cpp that uses C++11/C++14 standard?
It will help reduce code size, make better API and increase performance.
Before starting any work, I would like to understand whether this would be useful for the community and align with the project direction.

Hi,

I am trying to pull Billing Profile from 2 meters which consists of 103 objects & 64 objects from an embedded device. As a process i am reading capture objects and going for data read.

Data from the meter is completely read and during the parse stack at the embedded module is throwing an OUT_OF_MEMORY error (0X0104).

Meter 1 Info
Communication Mode:- Serial (UART)
Communication Protocol:- TCP Wrapper
Communication Interface:- NIC Port

Hi sir,

I'm not able to generate apk file by clone the project. Please guide me to generate app by Android studio

I would like to ask about the implementation of the Auto‑Connect class in Gurux. Is it possible to simulate this class in the Gurux DLMS Simulator? My goal is to create a program that can simulate GPRS‑style sending and receiving, and I am specifically interested in the byte‑level packet behavior.

I also have a question regarding Protocol‑E communication. After the meter switches to the new baud rate, I am not receiving the expected ACK frame. Could you clarify what might cause this issue or what the correct sequence should be?

Thank you.

Hi,
i see that the getting Generic Profile value using ReadRoiwbyEntry has different encoding parameters on cpp and c implementation, i am addressing to:
In cpp: https://github.com/Gurux/Gurux.DLMS.cpp/blob/master/development/src/GXD… it encodes the start index and count as UINT32.

I need to simulate a DLMS meter using DLMS server application using C and GPRS communication. I have compiled the source code without any errors.

I tried to run DLMS client application(python) and DLMS server application(C) in two different boards. But the connection establishment is failing. Can you guide me on how to establish connection between client and server using GPRS?
Dynamic IP address is assigned on both boards.

Im getting following error when I tried to read the data from other board (meter simulator)

Hello, i wanted to get more information about pre-established connection, because i want to use DLMS with smart water meter on NB IoT.

We are writing Passive TOU day profile which have 4 day table and 8 rate in each table, when we write all 4 day table with 8 rate in all table and it start transfer success for 2-3 packet and post this next command failed and getting error "Service Not Allowed", but when we reduce the data means select only few rate in all table so getting all success.
We analyse that if Payload size is <512 Byte able to write successfully in block transfer, but if no. of payload >512 byte this scenario regenerated using library as well as DLMS director.

Hi all,

We have ~500 ameter300 DLMS meters deployed across the country. They all use the same key material (system title 5753450000000001, client title 434C4E5400000001, auth key D0…DF, block key 00…0F, GMAC password 0x3333…). The legacy OPC client (C# / MyDaAddressSpaceDevice) talks to them just fine, but it hardcodes Ciphering.InvocationCounter = 1.
