Hi,

Why when sending from client to server Receive Ready incrementing receive number sequence? In DLMS GreenBook 8.4.3.3 writed:
The Receive ready, RR, frame shall be used by a data station to:
a) indicate that it is ready to receive an ***I frame(s)***; and
b) acknowledge previously received ***I frames*** numbered up to N(R) - 1 inclusive.
When transmitted, the RR frame shall indicate the clearance of any busy condition that was initiated by the earlier transmission of an RNR frame by the same data station.

Hi Mikko,

I am using this version "Gurux.DLMS.cpp-master_20201208.1" for my client application.

The scenario is that I have a DCU and 2 or more energy meters are connected to DCU. I have created different logical servers (17, 18, 19, 20...) in the configuration of DCU for each meter. The DCU is able to fetch data from each meters at its level.

Is it possible to fetch data from each logical-server with single connection but different logical id?

Thanks,
Pradson

Hello,

i want to ask, just to clarify. What is the difference between a Push Message and Serial Message.
My understanding is that a Push message via RS485 line is something like this:

/AUX5905000681

Hello and happy new year,

When sending the SNRM trace using GXDLMSDirector it works and the communication with the meter is perfect. But in the C# library, we are not able to send it with the following configuration:

* Max payload size in transmit = 228
* Max payload size in receive = 228
* Window size in transmit = 1
* Window size in receive = 1

So we end up sending this:

Hi, I have a question. I want to get data from this OBIS - 1.0.15.6.0.255 class 4.

Command:
python main.py -h 153.121.114.08 -p 5 -a Low -P 31323435 -t Verbose -r ln -c 20 -s 255 -g 1.0.15.6.0.255:4

It seems the command printed all the data. Is that the right command to use?

Thank you in advance.

Hello!

I have a problem with Gurux.DLMS for python on Raspberry PI 4.
I'd like to read data from meter Landis Gyr E650 using optical interface with USB. I connected USB to raspberry and I've done step by step your instructions for python Gurux.DLMS.

I check a connection meter Landis Gyr E650 and optical interface with USB on GXDLMSDriector (Windows10) and It works. I can read data.

My output of console is below.

Thank you in advance for your kind assistance.

Hi Mikko,

I am using latest version (20201208.1) of Gurux.DLMS.cpp-master. I have two sample application. Both sample application are running in same machine and showing different time format.

Ideally machine time format should be shown by the both application?

Kindly find the attached screenshot for the same.

Thanks,

Hi, I'm having a problem when I use an xml file with several OBIS codes to perform readouts with the xmlClient. Sometimes the responses get mixed up.
These are the OBIS codes I'm reading
