Dear kurumi,

Hope you are doing well.

Excited to become on forum after long time it's around 2.5 years.

I am developing indian standard and for that i have implemented firmware upgrade association but gurux gives error on object list downlow.

Error : Index was out of range. Must be non-negative and less than the size of the collection. Parameter Name: Index

Data Log:
12:10:50 Collecting objects

it has only one object to download.

I have analyzed the received data from meter it looks just fine.

also, frame is decoded by gurux "DLMS Translator"

also i have tested the same with kalkitech where object list get downloaded successfully with same log.

could you please help to fix this issue.

Best Regards,
Aoudumbar Pawar

Hi, You are returning…

Hi,

You are returning ImageTransfer without the AssociationLogicalName, which is mandatory. Without that AssociationLogicalName version information is missing, and the client thinks that you are using AssociationLogicalName version 2, but I can see that you are using version 1.

After you add AssociationLogicalName to the association view, it works as expected.

BR,
Mikko
