Hello Mikko,

I'm getting an error dialog box of "Invalid Authentication Key", while adding device in GuruX software.
I want to test meter according to "Indian standard" for "Meter Reader Association". The procedure I followed is as below,

1) Selected Indian Standard as manufacturer.
2) Start protocol as DLMS, Logical name referencing is selected.
3) Authentication is low, client address is (32 in decimal format), 20 (hexadecimal format).
4) Added password and other relevant information.
5) In secured connections tab i selected security as "Encryption".
6) Added System title and Block ciphering Key.

When I clicked on OK i was getting error dialog box as invalid authentication key. As my security is Encryption only, then there is any need to add authentication key?

Have a good day..!!!

Thank you and Regards,
Anudeep

Hi Anudeep,

Hi Anudeep,

I believe that you are right. There is no need for authentication key if you are using only encryption.
Set the 16-byte value to the authentication key. It's not used if you are using Encryption only. This is fixed to the next release.

Mikko
