Hi,

Are you using Java ME or did you just select that group?

2. DLMS is not that simple protocol. You need to establish the connection to the meter and then you can read data from the meter. DLMS is standard and it's described in multiple documents.

Hi,

I did get the latest version from the server and client from GitHub and ran tests and everything worked without problems.

I noticed that you tried to read 0.0.66.0.1.255. So you have added new objects. You need to check your code and make sure that you are handling profile generic objects correctly on the server side.
