I am using Gurux DLMS C library.

Hi,

Your meter is using four bytes, but it's possible to use logical and server addresses with two bytes.

Can you communicate without problems with the meter?

With DLMS director I can communicate with device, but I can't reach my device with Gurux DLMS C library. Is it possible to solve this issue by myself (without patches)?

Probably there is no support for DLMS protocol version 2?

Hi,

ANSI C client is improved so it can handle this. Get the latest version.

hi, I updated to latest version and now when I want to disconnect, i am sending multiple disconnect payloads. Is this intended?
