Hi Kurumi,

I have worked on basic PC association by adding different objects, read and write attributes value with GuruxServer in ESP32.
Now we are trying to work on US Association with encryption and authentication. Could you please share any basic example for US Association from ESP32 GuruxServer

Thank you

Hi, Mikko,

For single metering manufacturing company should same logical device name for all meters or different. as stated in blue book in clause no. 4.1.8.2 that

Each COSEM logical device can be identified by its unique COSEM LDN. The LDN is defined. as a string of up to 16 octets.
i am mentioning example in both way that which one is correct.

condition 1:-

METER METER SR. NO. LOGICAL DEVICE NAME

Hi,

I read the association.
Object 0.0.96.1.19.255 has access

"<Access>13</Access>".

Director display in filed Access - "NoAccess".
Before read this attribute I use a condition

if (_client.CanRead(obj, index))

that returns - true.

Feld "Access" of this attribute has a value "ReadWrite"
Feld "Access3" of this attribute has a value "NoAccess" and this is correct.

Please tell me how to make it return the value "NoAccess"?

Thanks.

Hello Sir,

I am working with the following HDLC frame:
byte[] frame = GXCommon.HexToBytes("7E 16 38 04 7E A0 1F 21 03 96 DB D6 E6 E7 00 C4 01 C1 00 09 0D 41 4C 4C 49 45 44 2D 44 4C 4D 53 30 33 D6 B5 7E");

Using the GXDLMSTranslator, I am able to successfully convert this frame into a readable XML format:

GXDLMSTranslator t = new GXDLMSTranslator();
string xml = t.MessageToXml(frame );

However, when I use the GXDLMSSecureClient to process the same frame, the result is false:

I am unable to generator the simulator template file. Its taking lots of time.

Hi,

I was looking at the following file:
https://github.com/Gurux/Gurux.DLMS.Python/blob/c6738ce24bd56a265264131…

I noticed that the list of object types isn’t complete.
For example, if I want to read a Compact Data object (DLMS_OBJECT_TYPE_COMPACT_DATA, IC=62) or LTE Monitoring data (DLMS_OBJECT_TYPE_LTE_MONITORING, IC=151), these object types aren’t mapped in _GXObjectFactory.py.

Unable to read attribute =3 (1.0.94.91.0.255) IC=7 for Indian Metering, while I'm able to read attribute 3 for other Profile generic class

I'm using python lib.

Code:
inst_obj = GXDLMSProfileGeneric("1.0.94.91.0.255")
read_inst_profile = b''.join(secure_client.read(inst_obj, 3))
print("\n→ Read inst buffer:", read_inst_profile.hex())
ser.write(read_inst_profile)

Hi All,

I’ve implemented decryption logic using Gurux DLMS in both Python and C# for handling secured DLMS/COSEM communication. Below is a summary of the work done along with current observations and questions.

Python Implementation:

Incorrect current values ​​for Landis Gyr E570 meter

Hi,
I wrote a function that should return current values, but instead of correct values ​​I get incorrect values, e.g. 0 values, or negative values.

What am I doing wrong?

Here is the function:

@app.route('/read/<int:meter_id>/<string:obis>', methods=["GET"])
def read_value(meter_id, obis):
print(f"DEBUG: Proba odczytu OBIS {obis} dla licznika {meter_id}")

reader = None
connection_key = None
