Respected Sir

For the Arduino how can we get integer or float values of Voltage , Current etc.
The data is returned in the example as a structure

Secondly My code is
gxRegister reg1;
cosem_init(BASE(reg1), DLMS_OBJECT_TYPE_REGISTER, "1.0.12.7.0.255");
com_read(BASE(reg1), 3);
com_read(BASE(reg1), 2);
obj_toString(BASE(reg1), &data);
GXTRACE(PSTR("Voltage"), data);
obj_clear(BASE(reg1));
free(data)

Hello,
This is my first post here, you're doing a great job with this project, I found many useful information here :)

Anyway I'd like to ask you about a problem with reading the data from Landis E550. I've managed to set the communication with the meter but I got stuck when I try to force a read command. Here is what I get:

-> /?!
<- /LGZ5\2ZMG410000b.P07 //(device responds correctly)
-> <ACK>001 //(I've decided to stay with 300bps)
<- P0.(BE00B600) //(device responds correctly)

Dear DLMS Experts,

I try to compile DLMS source code with Arduino Mega 2560. I already copy the src and include folder from development folder into the Arduino_IDE server folder. I click the compile button then Arduino IDE displays an error. Please see my attachments.
Is there any file to edit ? Hope my attachment could help you to find the problem. Thank you.

Hi,
I am using GuruxDLMS.c to try reading object logical name 0.0.0.2.1.255, attribute 2, HLS using GMAC, connects ok.

Following the http://gurux.fi/Gurux.DLMS.Client readObject example.

The call to cl_updateValue causes a hard fault due to an impossible pointer value.
I could track it to file variant.c, line 373, data->Arr is not NULL but data->Arr->data has a value that is not reachable.
See the picture below.

I want to suggest rewriting the (because i can't make deepcopy GXDateTime: missing Offset)
class GXTimeZone:
def __new__(cls, offset):
local_time_delta = datetime.timedelta(minutes=offset)
if offset == 0:
name = "Z"
else:
if offset > 0:
name = "+"
else:
name = "-"
name += str(int(offset / 60)).zfill(2)
name += ":"

Hi,

I have been using Gurux for DLMS test developments. One of my customer wants to check if my app is compatible with DLMS standards.

Is there a tool in Gurux that accredits data exchange standards in DLMS reading to check compliance? Or if there is a solution that we can use as a third party for this process, can you share it?

Thank you,

Hasan

Hi Mikko. I want set GXDateTime type in default: FF:FF....(for activate_passive_
calendar_time in id20 ActivityCalendar). How can do it?
ps: and in director too

Hi,

i am working on electric meter. I upload Gurux.DLMS.c arduino code to NodeMCU(ESP8266) to read the meter throught Optical Port. The uploading is successfully done, but it cannot access the meter.

The output (also it is shown on the image attached):
---------------------------------
Start reading:
SnrmRequest
data length : 10

Hi Mikko,

I am testing IS15959-2 meter.

Following is the AARQ and AARE payloads.

AARQ:

In AARE validation got "ServiceError Initiate Error exception. ApplicationReference ApplicationContextUnsupported" Error Message.
