Hi Mikko,
SecuritySetup for High Association(0.0.43.0.3.255) Activated as AuthenticationEncryption policy.
But next time when i am connecting gurux through none mode it is connected successfully.
Similarly happening in MR Association also.
I am thinking that connection has occur through Security: AuthenticationEncryption instead of NONE.
Please help me where is the wrong.

Hi,

Have you checked this video?

This is not implemented to the meter if you can connect as normal. You need to ask the meter manufacturer to add it.

Hi,

Each association view should have its own security setup object. When you activate the security policy it will affect only that association view. IN ANSI C source code this is done in svr_isTarget.

Try to connect using GMAC authentication. Then change the security policy to Encrypted and you can't connect without authentication when you use GMAC. Ciphering is not required If you try to connect with Low authentication.

Mikko
