Hi all

may be you can help me to read itron sl7000
i already can connect to meter
but i can not get obis code, the information was invalid

Hii Mikko,
I want to implement GMAC authentication.

Below are my some queries:
1. Is it compulsory to exchange client-servers system title in AARQ and AARE before pass 3 and 4
2. if suppose i am not included server systems title in AARE then what will happen.
3. How to authenticate the GMAC at server side which is received from the client
4. Which IC (invocation counter) must be used at server side during calculating GMAC

Also can share the frame log along with pass 1 ,2 ,3 ,4 (HDLC)

BR,
AP

Hi,

I am trying to read data from the iskra MT880 with DLMS using python and serial port, but it has been impossible to extract the information.

When I run the code, I get the following response:

gurux_dlms version: 1.0.104
gurux_net version: 1.0.17
gurux_serial version: 1.0.15
Authentication: Authentication.NONE
ClientAddress: 0x10
ServerAddress: 0x4f

But then I get an error saying "Resource temporarily unavailable".

How can I fix this and be able to read the data from the meter?

https://www.gurux.fi is not accessible

"An error occurred during a connection to www.gurux.fi. PR_END_OF_FILE_ERROR"

And as a result the GXDLMSDirector cannot download manufacturer settings.

However Http is working. Is there a way to manually download and install the manufacturer settings?

Hi Mikko,
we are facing encrypted data parsing problem with latest gurux tool, with previous version we don't have any problem both request and responses are got parsed, but in current version only requests are parsed not the responses, the tool library version also attached. Plz check the below given traces ,here the block-cipher key is 1111111111111111 (in ascii),

I launched gurux.dlms.python/Gurux.DLMS.Client.Example.python
I have an Itron Actaris SL7000 meter connected via RS485 via an RS485-Net converter.
I connected, I read the registers, but the reading takes place from 8-12 attempts:

Tried to make Gurux.DLMS.cpp\GuruxDLMSClientExample

First the error appeared:

Hi,
whenever we are sending push encrypted data with GBT mechanism, the frame not parsed by the gurux tool ,may be there is a problem in frame, would you please suggest us, what are the bytes we are missing or what are the bytes we added additional. The Blockcipher key is :1111111111111111(In ASCII all ones).

Hello, can you explain the purpose of this lock in your Reader example?https://github.com/Gurux/Gurux.DLMS.Net/blob/3b6f2e34f7a386a7d78baf3617…
The problem is I have a deadlock in my application. So I`m analyzing all potential places in the code that could cause deadlock.

Hii,
Trying to communicate with meter in suite1 with following configurations but getting wrong decrypted data.

Security suite : 1
key agreement scheme: static unified model.
authentication : high

Following inputs are used to decrypt the received cypher data:
1. Encryption key : key derived from kdf function.
2. Authentication key : key derived from kdf function.
4. AAD (general cyphering: SC || AK || transaction id || orig. sys. title || Recp. sys. Title || date-time || other info
