as my further comment got somehow "lost" or was "deleted" (as it was a comment to an old topic) I'm opening a new topic concerning my problem accessing in an authenticated way a L&G e650 meter via Gurux Python Example Client.
My problem is that all tries fail with "Authentication failure" when using Gurux Python Example Client. Non authenticated access works without any problems.
As I was able to test/access the meter via L&G map.110 Windows Software. Low.Authentication as well as High.Authentication worked like a charm. Therefore I'm 100% sure that the password itself is not the issue.
I'm using the following CLI command to access the meter (XYZXYZX is a placeholder to not provide the real password here).
python main.py -S /dev/ttyUSB0:300:7Even1 -r sn -i HdlcWithModeE -a Low -P XYZXYZX -c 32 -L LGZ
