Hi!
I am trying to connect to a meter (which is in server mode, as I understand it should be) using DMLS director. And whatever I try, I keep getting rejected.
What I send:

What am I doing wrong, here?
The diagnostic info from the meter is not very helpful.
Thank you!

Hi,
What meter did you try to read? Returned Associate-source-diagnostic is invalid and it is not in the standard.
You should ask this from the meter manufacturer and ask them to fix this. Reason for the failure might be anything.

The meter is a Ningbo Sanxing Electric Co.,Ltd SX5A2-SELS-04. It has a DMLS User Association Certification number 1248.
I also suspected they are not according to standard since Gurux and also Wireshark dissector are failing to read any of their responses.
Weird they have this certification that they passed DLMS/Cosem Conformance test.
Thank you for helping!

Hi,
One thing what you can try to do is change server address 1 and client address 10. Now it is 11 (0xB).

Unfortunately the result is the same:

I tried several combinations of client and server address, without success.
I think only the manufacturer can help, if they are willing.
Thank you for your support!

Hi,
I checked meter reply and it's not correct. ResultSourceDiagnostic is 0xFF. This value is not correct. Standard defines values from 0 to 14. So there is an issue on the meter.
