I am trying to connect indian standard meter but it is throwing one exception ServiceError Write Exception: Service Unsupported. Earlier it is connected once and I am able to access every objects but now not able to connect .Below is the hex traces

We failed to set the rtc clock of meter using Gurux UI, may be due to some limitation of ms in timing of the meter ,
Is there is any Gurux python library is available so that i can try using the script?

Also i want to go the all the configuration of meter using Gurux python library, Can you help for the same.

Hello, please help me,

When I try to load my collectionObject file using the method, GXDLMSObjectCollection.load from the gurux library for python, I get the error: can only concatenate str (not "GXDLMSData") to str.

The file is saved in .xml format and the structure seems correct. Below is an extract from my code:

Hi

I want to connect Wasion iMeter318 using a serial port what is the configuration to connect it?

How to add the kW, kVA in scalar units as there is no value defined in the DLMS blue book.

How is DLMS meter reading possible using MQTT protocol, what is the advantage of using MQTT over dlms wrapper to read meters?

Newbie here, "Hello"

In HDLC Mode protocol disconnect from meter looks something like this:

HDLC Flag: 7E Frame format: A0 Frame length: 07 Dest and Source addresses: 0303 Control field: 53 HCS: 80D7
HDLC Info.: FCS: Flag: 7E
SEND: 7E A0 07 03 03 53 80 D7 7E
RECV: 7E A0 20 03 03 73 F0 2E 81 80 14 05 02 00 F8 06
RECV: 02 00 F8 07 04 00 00 00 01 08 04 00 00 00 01 58
RECV: 71 7E

How do you protocol disconnect in IP mode from meter? (not TCP disconnect)

Thxs,

Hi!

If encryption and authentication is used in DLMS, we need an encryption key (EK) and authentication key (AK).

The authentication tag is created using the AES-GCM algorithm, using the EK. From my point of view, the packet is then already authenticated by the owner of the EK because AES-GCM provides authenticated encryption.

I wonder, what is the purpose of adding an AK to the additional data of the crypto protection?

Thanks for any comments.
