AARQ with General block transfer - Encrytion missing in Get

Hi,
I connect to a meter with authentication=HLS, services=get,set,getblocktransfer,serblocktransfer etc, I can connect successfully and read all parameters. But, if I add Generalblocktransfer to the services, I can still connect successfully; but when I try to read any parameter, Gurux sends plain text to the meter, without encrypting it.

Thank You

Hi,

You need to set correct settings fo the "Secured Connections" tab when you create a new device.

You need to change following settings:
Set Security to AuthenticationEncryption.
Set system title, authentication key, and block cipher key.

Hi,

Hi,
I have already set correct settings and I am able to connect and read with authentication and encryption. But, the problem comes when I add General block transfer in the services. After that when I connect it shows connected. But when I read clock object it sends plain text to meter instead of encrypted. But, if I remove the General block transfer service, it sends ciphered text and gets the correct response.

Hi,

I just verify this and you are right. We have broken this at some point. We'll fix this ASAP.
Testing will take a few days, but we'll try to release the next version during this week.

BR,
Mikko
