Firmware Upgrade is pending at Verification Stage

DLMSDirector

Hi,

I am trying to upgrade firmware to a TCP wrapper meter using GXDLMSDirector.

During the process, Gurux application is retrying image verification stage indefinitely until the disconnection request or power off.

GXDLMSDirector Application Version:- 9.0.2409.2004

I have attached log for your reference.

Hi Murali, Your data is…

Hi Murali,

Your data is encrypted, so it doesn't help because you didn't give the block cipher key.

The meter might reply temporary failure error, which means the image verification is still in progress, and the client should try again in a while. That is done until the meter returns success.
