Se connecter à plusieurs compteurs sur la même adresse IP et le même port.

Forums
Gurux.DLMS

Bonjour, j'ai 350 compteurs smartESOX de chez APATOR et 33 concentrateurs.
Cependant je n'arrive pas à me connecter à plusieurs compteurs sur la même adresse IP et le même port. J'ai donc crée un programme de test qui est composé de 3 compteurs qui partagent la même adresse ip et le même port.
Je réussi à me connecter au premier compteur mais les deux autres compteurs échouent au niveau de _reader.InitializeConnection(); .
Vous trouverez ci dessous le code de mon programme de test. j'utilise c#

FRMR frame reason

Forums
DLMSDirector

Hello Mikko,

I'm investigating meter behaviour in unstable low speed GSM channel condition.
To describe in short - a lot of ping loss situation.
Just a few moments after every 'Data send failed. Try to resend message x/y ' I've got an unacceptable frame even in case of restored data exchange.

Still can't decide is it a meter firmware problem or a DLMS Director problem - some of them unable handle temporary tcp/ip link availability problem.

Problem with Dedicated key on Release request

Forums
Gurux DLMS for ANSI C++

After updating to the latest version of gurux.cpp (I had a very old version), i'm having problems debuging because an assert.
The problem is that after AARQ, the m_DedicatedKey stored in the GXCipher has position advanced.
Then in GXAPDU:233->GXByteBuffer:406, when trying to set the dedicated key, an assert throws because pos is already it's max size.
I'm able to reproduce this behaviour every time. Can you fix it?

Query on RF Communication in Smart Meters

Forums
Gurux DLMS for Java

Hi Team,

I am working on implementing RF communication for smart meters and need some guidance on the following:

What are the initial steps required to establish RF communication with a meter (hardware setup, protocol, initialization process)?

What are the key variables/parameters that are transmitted during RF communication (e.g., addressing, payload structure, control fields)?

Any documentation or reference would be helpful.

Thanks.
