How to read multiple meters(uses SN referencing) from a physical device?

Forums
General discussion

I came across a set up of few DLMS meters (Landis Gyr) which uses SN referencing where they have been configured within the same host.
In a single IP, we could see multiple meters are configured. Can anyone direct us on how to get the server addresses of configured meters so that I can read the objects of the same using below command.?

GuruxDlmsSample -r SN -c 16 -s [serverAddressOfMeter] -h [IP Address] -p [Port No]

HLS WITH GMAC

Forums
General discussion

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)

I cannot read data from iskra MT880 with DLMS, python and serial ports.

General discussion

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?
