Hi Mikko,
I'm trying to connect our meter (based on gurux.dlms.java library) via our contractee's client program (based on Gurux.DLMS.Net library).
This client only support secured connections with ECDSA certificate, and it works well with other meters.
But when I try to connect our meter using this program, it always shows 'Unknown tag' error like below and connection failed.

When I asked contract…
When I asked contract company, they said it use an ephemeral key using ecdsa certificate and private key.
I think I need to check this and ask again later with a new post.
Thanks and regards.
