Hello, GuruX!

I have some issues with authentication and writing to ActivityCalendar. Let me elaborate on my problems.

1. Authentication problem

After upgrading version of library gurux_dlms from version 1.0.91 to 1.0.94 I can't connect with the meter. My code to connect looks like:

Hi everyone,
I'm an electronic engineering student and I'm working on a smart meter reading project. I am testing the provided example code in python to implement it on a raspberry Pi. I am looking to have connection to the meter as shown in the example of the python code with serial communication. However, I get an error sending data "Data send failed. Try to resend 1/2". After two attempts, the disconnection request is sent automatically. How can I solve this problem?

Hi Mikko,

I am reading Block load profile from IS15959-2 meter having TCP Interface.

Some time all entries were read successfully while sometimes getting an error as below :

"Invalid Block number. It is 3 and it should be 4."

Can you please provide an update on this

Hi Mikko,

I am testing IS15959 -2 meter.

I have written the local time into the meter. And also getting the same date and time and shown properly in GXDMSDirector.

Now, I have changed my local system time to UTC time. And directly read the time from the meter and is shows UTC time instead of time set previously,

Even also I have tried with the option given in the Advanced tab in GXDLMSDirector.

Can you please check and provide an update.

Hi Mikko,

I have integrated "Gurux.DLMS.cpp-master/GuruxDLMSClientExample" in my project. This application reads information periodically (interval basis like every 1 second or 2 seconds) from the meter. I want to test this client application with 1000+ actual devices but I have only 2 devices. Can I use "Gurux.DLMS.cpp-master/GuruxDLMSServerExample" application instead of actual device without any challenges?

Kindly suggest me asap.

Thanks & Regards,
Pradson

Hello,

I am reading rows of a profile generic object by range

dlmsClient.ReadRowsByRange(
profileGeneric,
new DateTime(2020, 10, 15, 0, 0, 0),
new DateTime(2020, 10, 16, 0, 0, 0)
)

And receiving 8 frames in response with 974 bytes of data.

I can see that response contains the real data, but unable to parse it:
dlmsClient.UpdateValue(profileGeneric, 2, replyData.Value);
always gives empty buffer.

Hi, I have a quick question regarding DLMS standard itself.

I was reading (with java) an Itron meter and I found out, that association gave me multiple objects with same LN name.

I made a quick check for removing any duplicities, but then I discovered, that some of those objects have different Object type. (You can see it below)

I always assumed, that meter can only contain only one object with same LN name. Is it true, or DLMS allows this or only when objects have different object type?
