Hi,
We can't repeat this. It works without problems. Can you check your "Secured Connections" tab from the meter settings? What is the used security level?

Hi Mikko,
Hi Mikko,
Thank you for your reply,
there is newly securitysuite: GMAC showing.
Actually I am connecting PC Association I did not given any security related data at secured connections.
please find below screen shot.
similarly for remaining association also it showing as same like this.
Hi Mikko,
Hi Mikko,
but in code i am using security_suite as :DLMS_SECURITY_SUITE_V0
this option is not available in the secured connection tab in the meter settings.
Hi,
Hi,
DLMS_SECURITY_SUITE_V0 is GMac. You need to set authentication and block cipher keys if you want to use security suite 0. They must be the same on the client and server-side.

Hi Mikko,
Hi Mikko,
for US and MR I given authentication and block cipher keys and for PC association I given NONE.
In three Associations I am getting the problem. I am not able to read individually.and i given Security-suite as GMAC
Hi,
Hi,
Can you read anything? First, I have to say that you need to verify that the keys are the same on the client and the meter. This is usually the reason.

Hi,
Hi,
You have set access conformance for the meter side. Remove it from the meter side. Access is using a lot of memory and it's not implemented for the meter side for that reason. Using the access service you can read or write several objects with one command. It's a good idea, but some people try to read multiple profile generic buffers at the same time and it's using too much memory.
BR,
Mikko
