Hi Mikko,

I am trying to read Profile entries for Block Load with all options. In which reading by range & All, are working as expected. However, reading by range and last entry reading will not work with the error of "Invalid Data Checksum".

Please do the needful.

Thanks & Regards,

Hi,

"Invalid Data Checksum" means that the meter is sending an invalid HDLC frame. I can verify it if you add the last frame here.

Hi,

Is the meter answering at all after this or do you need to boot it?
This seems like a meter issue.

Hi,

There is no "Invalid Data Checksum" error in your trace. When you are receiving it?

Hi Mikko,

I found that error on UI only.
