Reading objects in US Association

Hi Mikko

I have successfully established connection with PC and MR associations. Getting server to client did not match error after the arq request with US association. Do i need to make any changes in GXDLMS reader module?

Hello Mikko

I can successfully execute PC and MR associations of client example program without any errors. But when i try to establish connectivity in US mode, i am getting either the 'server to client does not match' error or an authentication failure error. Please let me know if there are any additional setttings or changes that needs to be done before executing in US type. I have revalidated the passwords and keys and they are as expected. I am pasting the trace below from cmd.

Hi Mikko

I have confirmed with the team and they are sure that the MR and US passwords are set different.

Hi Mikko

I have checked regarding challenge, there is no specific challenge that needs to be used while making connection. Is there anyway that i can check and validate challenge from meter?
