Firmware Update : Unavailable Object Error Response

Hi Mikko,

I am trying to update firmware into IS15992 standard meter.

In firmware update, all blocks (Total 625 blocks) were transmitted successfully.

After completion checked for all block transferred status. In that getting 589 were successfully updated out of 624 blocks.

Again started firmware update and it starts from 589 and again all blocks were updated successfully.
Then checked for all block transferred status and again got 589 from the meter.

I have checked from DLMS translator and in that show "<Result Value="UnavailableObject" />" error.
