Good day sir,
First of all, thank you for creating this DLMS library, it makes me able to learn and know so many things from my meter. I'm able to connect to meters using settings provided by the meter provider, and read needed values from it. Currently I'm able to read meter from EDMI, since that's what I have. I used Gurux DLMS C for that.
Now I want to learn how to create a gateway, so I can be able for example connect to multiple meter.
the connection is like this:
my windows pc -- raspberry pi -- meter 1

Could you please clarify why the bit string 100001 is used as the value for the protocol-version field in the AARQ APDU?

I have analyzed multiple AARQ exchanges across different tools and interfaces, with specific focus on how the protocol-version field is BER-encoded and interpreted.

Hi,

Is it possible to communicate with the dlms server (which I'm using as virtual smart meter using PC) using serial port connection from dlms client?

Hii ...
I have successfully compiled the client and server source code from dlms c libraries. I am using server source code as simulated smart meter in my PC (I'm not using real smart meter). How to setup the tcp port (both client and server side) and access the data from simulated smart meter ?

Hi,

I can able to read individual Data type object. Using following methods.
Client.init(true, 32, 1, DLMS_AUTHENTICATION_LOW, "xxxx", DLMS_INTERFACE_TYPE_HDLC);

cosem_init(BASE(ldn), DLMS_OBJECT_TYPE_DATA, "0.0.42.0.0.255");
com_read(BASE(ldn), 2);

Long seances (hundreds of HDLC packets) ended with "Invalid frame..." errors. Same readings in Director are OK. Different devices.

What can I check by myself?

I want to build client.ino example for ESP32 from "GuruxDLMS.c\Arduino_IDE\client"
https://github.com/Gurux/GuruxDLMS.c/blob/master/Arduino_IDE/client/cli…

I have added following as Additional Board Manager URLs
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/pack…

gxaes.c include wrong file
#include "../include/errorCodes.h"
must be
#include "../include/errorcodes.h"

Strange device works in "Director" only if checkbox "use frame size" is checked in "device properties".

How to set same option in C library?
Or is there other way to limit frame size?

please give document of below obis code
