  2. Activate Firmware : Inconsistent Class

Activate Firmware : Inconsistent Class

Hi Mikko,

I am testing the Image Transfer feature.

All blocks were transferred successfully, and also verified the image.

When I am going to execute the method to activate the new image, I am getting the "Inconsistent class" error response.
Payload: c701c10900

Can you please provide your valuable suggestion, when this erro will come and how
to resolve that ?

Hi, Was the verification…

Hi,

Was the verification successful? Is your meter restarting after you call Verify? Some meters return an error for activate because it's not implemented. Some meters return an error and restart when you call the Activate.

DLMS standard is quite open for firmware update and meter manufacturers have implenent that differently.

BR,
Mikko
