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

Hii,
while reading the object 1.0.99.98.0.255 from DLMS server (C code) , I'm getting below error.

-------- Reading 7 1.0.99.98.0.255 Ch. 0 Event log #1

Hello everyone,

I'm working on a tool to virtualize a low-voltage TLSBT meter using the Gurux.DLMS.Net simulator. I cloned the real device using GXDLMSDirector and generated a valid XML file, which I load into my simulator using the official GXDLMSMeter.cs class.

My goal is to replicate the behavior of the real meter, where, upon connecting with ClientAddress = 1, I can see multiple GXDLMSAssociationLogicalName objects listed:

Hi everyone,
I tried to read a electrical meter with gurux python library buy I'm facing with an error below. I installed gurux dlms library on raspberry pi 5 and I connect the meter with probe to the raspberry and I'm not able to reach it. I have an Exception("Serial port is not selected.". can you please have an issue to my problem. Thank you

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.

I have a problem reading the Iskraemeco meter MT880. Here is my setup:
- manufacturer: Iskraemeco
- Interface: HDLC
- authentication: low

- Address Type: Default
- Logical server: 1
- Media: Net
- Logical Name Referancing - check
- Client Address: 1
- Resend count: 3
- Physical Server: 39 (Serial number: 76959423)
- Media: Net
- Host name: 10.249.11.4
- Port: 4003
- Protocol: TCP

I tried to connect E650 via RS845 port, use HDLC, low, 00000000, client address 32, serial number 95798354. After save the configuration and read from meter, it seems that DLMSDirector can read some data from meter, but maybe error make it stop. But the tree display is OK. I tried to connect and read the tree parameter, it can't work.
Can you help me fix this issue?

Hii,
I'm running DLMS python client code. Why the below prints appears on the screen? Does it cause error while saving the output to xml file?

Unknown object : 77 0.0.24.9.0.255
Unknown object : 76 0.0.24.8.0.255

Hi Mr. Mikko, I would like to ask you about the blockCipher , Authentication keys . I would like to know how the GXDirector Translate the digits of blockCipherKey and AuthenticationKey (example 2222222222222222 ASCII) when communicate with the meter with secured connection. What will the code be after the modification/translation that GXDirector will do?? What format will it have the 2222222222222222 key?

I am using Arduino client code on ESP32 to read meter in MR mode with LLS.
I downloaded the latest version of Arduino and using MR association with encryption. I get a message on terminal as
