Hi,

I use Gurux.c library and when i tested it with gxdlmsdirector ctt test
The Communication is ok between this two (Device and Software)
But when software was sent only this :

7e a0 2f 00 02 0e d3 03 10 5e 66 e6 e6 00 c8 1e
30 00 00 00 0c 63 a9 c6 fe 56 8e 96 a8 9f fe ed

Hi,

I’ve been working with the GURUX library for ANSI C and ran into an issue.

When I try to set the value of an object class_id = 1 and an attribute of type OCTET_STRING, I’ve noticed the following:

If I read the object first and then set it, inside svr_postWrite(dlmsSettings* settings, gxValueEventCollection* args) I get args->size == 1.

If I don’t read first and I write directly, then in the same function args->size == 0, which means no post-processing happens after the write.

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.

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'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

Hii,

I integrated dlms-client to one of micro controller using the reference of "GuruxDLMSDataCollector" and i am able to read Name plate and instantaneous profiles. But i tried to read billing and daily Load profiles but not able to reading . what i observed is the TX packet is not generating correct packet. But other two Profile generic data types Name plate and Instantaneous i got the correct data from meter.
So could you please help to overcome to read this daily load and billing profile.

Thanks & Regards

Hi,
i notice that: #define GX_ENUM(X) GX_UNION(&X, cVal, DLMS_DATA_TYPE_ENUM), in https://github.com/Gurux/GuruxDLMS.c/blob/master/development/include/va…
I think that should be: #define GX_ENUM(X) GX_UNION(&X, bVal, DLMS_DATA_TYPE_ENUM), (like in https://github.com/Gurux/GuruxDLMS.c/blob/master/development/src/varian…).

Hello,

I’ve successfully developed a DLMS host in C using the Gurux ANSI C library. It runs on a microcontroller with limited resources.

In the provided examples, the library uses dynamic memory (malloc()/free()). As you probably know, is not ideal on a microcontroller because memory fragmentation can happen.

To make the host more robust, I uncommented #DLMS_IGNORE_MALLOC in gxignore.h.
My problem is that I still need several functions declared in client.h, and those prototypes are only available when DLMS_IGNORE_MALLOC is not defined.

Hi,

Is this C library DLMS certified?
I understand that the user implementation based on this library can have issues due to verity of reasons, but this query is specifically for the library part.
