Hi everyone,
I tried to read a electrical meter with gurux python library buy I'm facing with an error below. I installed gurux dlms library on raspberry pi 5 and I connect the meter with probe to the raspberry and I'm not able to reach it. I have an Exception("Serial port is not selected.". can you please have an issue to my problem. Thank you

I am using Arduino client code on ESP32 to read meter in MR mode with LLS.
I downloaded the latest version of Arduino and using MR association with encryption. I get a message on terminal as

Hi, Mikko!

I fill Profile Generic class mydata (3 rows), but on read from Gurux DLMS Director shows two rows.

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);

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.).

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.

Hi, Mikko!

I have CGXDLMSVariant with octet string value date-time. Ho to convert it to CGXDateTime?
Is it possible to add function (or constructor) to CGXDateTime class for convert from/to CGXByteBuffer?

Thanks!

The device returns the correct value 522140, but after multiplying by scaler 0.01, returned the value 5221.40000000000005.

This does not happen with all data.

Below is a screenshot showing the code of file "GXDLMSProfileGeneric" with incorrect data conversion.

Please tell me, can this be fixed?

Thanks.

Hi Kurumi,

We are trying to understand what data is stored about the objects which we create using example
