Hi,

DLMS standard says that the Image Block Size must be smaller than the PDU size. Your image block size of 256 is too high. Can you give a higher PDU Size when you connect the meter? What size do you use for "Max PDU size" in the meter's Advanced tab? If your value is 65535 then you need to change the image block size to smaller.

BR,
Mikko
