Image Transfer-Data Block Unavailable

Hi, Mikko,

I'm developing a Java program to make image transfer, the meter is DLMS/COSEM conformed. During the upgrading process, the meter fw upgrading has been enabled, the image transfer has been initiated, but when the first image block is sent, I got an datablock unavailable error message. I continued to transfer all the blocks,and always get the above same error message. After all the blocks have been sent, I read the block status, all of them are 0. I searched here, and didn't find any clear illustration of datablock unavailable. By the way, the 1st transferred block is numbered 000000.

BR,
Jimmy

Verify that you write the correct firmware. Check the Image transfer initiate message and that your image size and identifier are correct.
