DLMSDirector

Hi

I'm trying to connect to meter with LLS. It seems like DLMS Director sends a disconnect request after pasing the reply. What can cause this? See log below.

Hi,

Your meter is returning Authentication Failure. Your password is wrong.

Do you see any reason why the meter will not accept the request from Gurux?

Hi,
This is interesting. What meter you try to read?
Following values are different.
InformationReport : This is not used in LN referencing.
client.LNSettings.ActionBlockTransfer = true;

You can't set those bits by UI at the moment. We have to think something.
If you can modify code add this to GXDLMSCommunicator.

public GXDLMSCommunicator(GXDLMSDevice parent, Gurux.Common.IGXMedia media)
{
this.parent = parent;
this.media = media;
client = new GXDLMSSecureClient();
client.LNSettings.ActionBlockTransfer = true;
}

Please, let me know if you have more issues.

BR,

Mikko
