Hi,

I believe that you are not allowed to establish the connection for your meter without authentication. You need to ask what authentication level you need to use to read your meter from the meter manufacturer or vendor.

Hello, Thanks for response, I also, tried with Low Authentication Level with client ID 17 with password, but same issue occurs.

Hi,

You didn't tell what meter you try to read, but I believe that your client address is wrong or then your meter doesn't support Low authentication at all. Some gas meters support only High or HighMac authentication levels.

Hi,

It looks like you should be able to connect without authentication. Try to propose only following conformances:

BlockTransferWithGetOrRead, Get, SelectiveAccess

Some meters can't handle if client proposes conformances that it doesn't use.

Data is correct, there is only settings that meter doesn't accept. Can you read the meter with other application so I can get the correct setings for you?

BR,
