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.

Hi, i'm using Gurux DLMS C.
I'm receiving APDU from the meter in binary format like below. I believe its simple APDU.
Please help me understand how to parse it with gurux C library.
Thank you.

Hello Gurux Community,

I have a meter that uses HDLC over DLMS/COSEM via optical or RS232 interface, working well with Gurux tools.

My backend HES sends and receives bare DLMS packets without HDLC framing or addressing. For example, a raw DLMS packet from HES looks like this:

How to prepare data to change the key after encryption. Found the C++ example in GlobalKeyTransfer(). Not sure how to convert it to C.
The expected DLMS translator output:

<MethodInvocationParameters>
<Array Qty="01" >
<Structure Qty="02" >
<Enum Value="02" />
<OctetString Value="24 bytes key" />
</Structure>
</Array>
</MethodInvocationParameters>

Thank you.

Using the API's provided, how to prepare the Profile General to look like in your example below? What need to be done before calling cl_write() to prepare array and structures.

Hi,

I am testing push message send using dlms C server example. I have configured the destination address and push object list. On the receiving side , python push listener client is used. How to manually activate the push message send from server side? Which function to be called to activate the push message send between the devices?

How to compile GuruxDLMSDataCollector with wirepas ? Im getting compilation error when I tried make command inside wirepas folder.

Hello,

I have a DLMS server running on a 32-bit MCU and a DLMS host also running on a 32-bit MCU, communicating via PLC. Both work correctly: I have created several objects on the server and can successfully connect, get the association view, perform read/write operations, and close the connection properly.
