DLMSDirector

Hi Mr. Kurumi, I have problem with XML tab of the DXLMSdirector . The password is converted correctly but the cipher key and Authentication pass is not. The software translate differently the key that I write ( I choose HEX as I did in password). I send you the exact case to understand what I mean.

The password is converted correct in XML: <HexPassword>AZkWXGUtEnrZ0ht0Dm/0mw==</HexPassword>

but the Cipher key is not HEX as I choose : <BlockCipherKey>00000000000000000000000000000000</BlockCipherKey>

how can I write as HEX in XML the cipher Key and Authentication pass???

Hi,

GXDLMSDirector checks the length of the block cipher key and if it's 16 bytes long it's ASCII and if it's 32 bytes long it's hex. So GXDLMSDirector handles this automatically.

Hi Mr. Mikko, thank you for your reply.
I have written everything correctly in accordance with the codes given to me by the manufacturer and with your instructions (the length of the block cipher key to be as HEX), i don't have the ECDSA keys and I haven't activated this option in the "secured connections" .
The meter stops responding just before final approval. There is a chance that the meter need this option (ECDSA keys) to give me final approval for the HLS Gmac Level?
I send you the communication log:

Hi,

Check that your authentication level and keys are correct.
It's not possible to say what might be the reason because the meter doesn't reply anything. You need to verify the settings from the meter manufacturer.
I believe that one of them is different from what the meter expects.

Hi,

I don't know what application you are using to read the meter so I don't know where keys are saved. You can't read the keys from the meter. The keys usually come with the meter as a separate document. You need to ask this from the meter vendor.

BR,
Mikko
