Out of Memory Error occurred when billing profile is queried by DLMS agent to server in L&T TCP Wrapper Meter. But it works when queried through GuruxDLMSDirector. Below are the access rights used:

Hello Mikko Sir,

As I discussed with you regarding communicating with smart meter via BLE (Bluetooth Low Energy) in this forum: https://gurux.fi/node/34855, you gave a reference for studying : https://gurux.fi/GXDLMSDirector.Media.

As I studied it, I was unable to find any help regarding the android app Gurux.DLMS.Android. I need to implement Bluetooth media in this app.

Is there a way to do so? Please guide.

Thanks,
Kshitiz

Hi kurmi,

we have implemented the Gurux server in esp32 and it is working fine, but the issue is with the push. I couldn't able to send the push with security. Can you please guide me through it.

Hi, Mikko!
In file gxsetmalloc.c i found duplicate if(). Row: 8426, function: cosem_setSFSKReportingSystemList().
if (value->vt == DLMS_DATA_TYPE_ARRAY)
{
if (value->vt == DLMS_DATA_TYPE_ARRAY) //duplicate if()
{
//.....
}
}

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.
