Serial Number Data Type

Forums
Gurux.DLMS

Good Morning Sir,

I am using Arduino client code on ESP32 to read meter in MR mode with LLS. I am able to read the Manufacturer name and Active Energy successfully. But when I read Serial Number with obis code 0.0.96.1.0.255 I get the ASCII string on HPL meter but a Octet String on Secure Meter.
I use the code as under
cosem_init(BASE(ldn), DLMS_OBJECT_TYPE_DATA, "0.0.96.1.0.255"); // OBis for Serial No
com_read(BASE(ldn),2); // Read
obj_toString(BASE(ldn), &data);

DLMS Short Name parsing issue: object 1.0.15.8.0.255 assigned SN = 0

Forums
Gurux.DLMS

Hello,

I'm using the following versions of the Gurux Python libraries:

gurux-dlms==1.0.181

gurux-common==1.0.13

gurux-net==1.0.22

gurux-serial==1.0.2

My DLMS meter only supports Short Name (SN) referencing, and I use the Python SDK (GXDLMSClient) to read register values.

During association view parsing (getAssociationView() → parseSNObjects()), I observed that the object with OBIS code 1.0.15.8.0.255 is returned with short name = 0, while all other similar objects are assigned valid short names (24, 48, etc.).

Accessing data from simulated meter

Forums
Gurux DLMS for ANSI C

Hii ...
I have successfully compiled the client and server source code from dlms c libraries. I am using server source code as simulated smart meter in my PC (I'm not using real smart meter). How to setup the tcp port (both client and server side) and access the data from simulated smart meter ?

DLMS Server in ESP32, Register object value save and load issue.

Forums
Gurux.DLMS

Hi Kurumi,

I am trying to write data in value attribute in register object and load using Serializer_Save and Serializer_Load. But I am facing issue with writing the data. Using GXDLMSDirectore when write some data and click on WRITE button, 0 is reflecting and in ESP32 server code, reference value is not reflecting the same. Its always 0.
