DLMS Java vs. GXDLMSDirector

Forums
General discussion

When I am using GXDLMSDirector and Server meter simulator everything looks good.
When I am using java package, request 0.0.40.0.0.255 is generated too before my own request defined. ( this.readObjects.add(new GXSimpleEntry<String, Integer>("1.0.1.8.0.255", 2));)
Why?

com_read: return 258 Invalid parameter

Forums
General discussion

Hello,

I try to read profile generic on SL7000 using ANSI C.
I read using "com_read" for "1.1.98.128.4.255", and attributeOrdinal value is 2. the return code is: 258 Invalid parameter

here it's the code:
cosem_init(&profile1.base, DLMS_OBJECT_TYPE_PROFILE_GENERIC, "1.1.98.128.4.255");
ret = com_read(&profile1.base, 2);

Heap Memory usage growth cause overflow

Forums
General discussion

Hello,
I used GuruxDLMS.c running on ESP32 microcontroller, to read data from SL7000 meter.
I have success to read meter clock & serial number, for testing I read it every one second.
after run for several minutes, the microcontroller is crash. when I monitor the Free Heap, it show the heap used several bytes after we call "com_read" function, so the available heap decreased every we call it, and causes system reset when it reach the lower point.

How to delete System Title from get/set frame

Forums
General discussion

Hi all,

I'm using an italian standard meter and our meters don't need system title during get/set request:

(example:
7E A0 36 02 21 03 32 6C C0 E6 E6 00 DB 08 00 00 00 00 00 00 00 00 1E 30 80 00 00 55 0E 89 E1 E4 0C A5 EB BB 00 5C AF D9 A5 F3 B8 B1 E1 7D AF E0 23 37 B9 85 10 71 2C 7E ,
08 00 00 00 00 00 00 00 00 is my system title (08 is the lenght) and if I delete this and set 00 as substitute, I can decrypt this frame correctly.)

There is a method to not add system title?

Thanks
