I am trying to make a new installation of the python DLSM/COSEM application. Testing the standard listener application gives the following feed back. What is the reason?

Hi Mikko, good day.

I have with me an Itron SL7000 meter. Using correct parameters I can connect to it and read some data using Gurux DLMS Director. I managed to read the daily load profile by range. Then i try to read using ESP32. I can connect to it using ESP32, but when i try to read load profile by range, the code throws some errors. Here's the code that i use:

Hello,

I have two variants of energy meters. I have taken the GuruxDLMSDataCollector example for dlms client integration in my MCU. One of the meter is working fine reading obis profiles without "update Invocation counter". But another meter needs Invocation counter this i verified with Gurux director so it needs "Invocation counter". So can you provide a piece of code for my micro controller for to read "Update Invocation counter".
It's urgent if possible can you provide me ASAP.

Regards,
Srikanth Jogi.

Hello.

Im triying to create a COSEM object class_id = 1 (DLMS_OBJECT_TYPE_DATA) of type structure. This structure will contain 4 different values. First 2 of them will be uint32 and last 2 will be int32.

The way i'm creating this object is the following:

gxData myMEASURES;
static dlmsVARIANT vUA, vIA, vPA, vQA;
uint32_t g_rmsUA, g_rmsIA;
int32_t g_rmsPA, g_rmsQA;
#define MAX_MEASURES 4
static dlmsVARIANT arrElements[MAX_MEASURES];
static variantArray arrBuf;

Hello,

I am working on a smart energy meter project and would like to establish a secure TLS communication using Gurux DLMS Director.

I have a few questions regarding the configuration:

How can I add or configure the CA certificate, client certificate, and private key in the Gurux DLMS Director tool?

Where should these certificates be placed — under Integration settings or Device credentials?

Is there any documentation or example available for setting up TLS/SSL (Port 4059) communication with a DLMS meter using Gurux tools?

Hi Mr. Mikko, I would like to ask you about the blockCipher and Authentication keys . I try to find the keys inside meters the main 4mb eeprom memory where the security keys is stored. The meter saves the most data(not all) ciphered in the main eeprom memory and I can’t locate the address with the saved keys. I have read with programmer the eeprom.
Is there some software to “translate” the ciphered hex dump of the eeprom memory?? Is it possible to help me?
I have been trying for months to do that with no success.

Regards Lambros

is there a way to read/write PushSetup.PortReference in DLMSDirector?

Hello, I'm very sorry to disturb you. I'm currently encountering a lot of problems when porting zephyr using your C source code. I would like to ask if your company has sample documents for porting zephyr projects that you can refer to me.Thank you very much
