Image transfer

Hi,

This is not defined in the DLMS standard and there are differences in how meters implement image update.

Image update is implemented to GXDLMSDirector as our customers have implemented the image update.

Hi, Mikko,

Finally search out this topic regarding verification with temporary failure. I'm using Director to upgrade firmware of the meter. The block has been transferred successfully into the meter. But during image verification process, since it will take some time to verify, the meter responded with "temporary failure" asking Director to wait and get image_transfer_status again until the verification process finished(Fig.11 in Blue Book). But Director prompts the "temporary failure" and then activation later cannot be taken effect, so the process finally failed. It is suggested to make a update on Director to accept the "temporary failure" response and proceed with process to succeed in the process finally. Thank you!

Best Regards,
Jimmy

Hi,

As per – Image transfer process flow chart - in the DLMS Blue Book, client should check Image Transfer Status in Loop upon receiving temporary failure.

I can not attach image here but it is on Page No. 126 of ed 17- part 2.
