Hi,

I have managed to get the Push packet with Data Notification Service packed under general global service and got following output at G-Director Notification Viewer :

Is there any setting by which Notification Viewer interpret the final APDU and show us the data encoded in frame same as we do manually by DLMS Transalator provided all ciphering information is fed via settings tab.

Thanks in Advance

Hi,

Select "Settings" from "Tools" menu and set system title and block cipher key.

Hi Mikko,

Thanks,

Keys and System Title already given still tool not decoding(decryting and interpreting) the PDU.

Do notification listener check invocation counter validity(IC shall be once more than last IC)?
From where does it uses Authentication Key as even for Encryption only mode we need to to have Authentication key as AAD input to AESGCM Alogorithm.

Thanks in advance

Hi,
Notification listener don't check the IV validity because there might be several counters and it also requires that there is a connection to the meter.

Authentication key is added to the new version, but it's not released yet. We try to release it begin on next week.

Thanks for the Update Mikko,

But then what is going wrong so that Notification are not interpreted. Is there any link with Push setup objects and their values?

Your questions and Hints will help me get to the root cause.

Thanks in advance.

Hi,

You should see the decrypted response if the keys are correct. Check your keys.

hi,

If i copy all the hex bytes received at Notification log in DLMS translator, I can see completely decoded and interpreted data and I have checked that Key(only Encryption) and SysT I mentioned in DLMS Translator matches with that of Device->Properties->Security Connections.

Thanks in Advance
