One possible conversion logic is: the data transmission device 100 puts the data received each time (downloaded data or delivered data) into a corresponding memory block, divides the data by adding a start address and an end address on the interface (or setting a divider or defining a separation mode by a user using a script language) to obtain a field identifier in the data, and then corresponds the field identifier to a target field supported by a target electronic scale according to a field mapping table, thereby realizing conversion.
For example, assuming that the delimiter is 3, when hexadecimal data of a fixed length is received: 010231323334350d0a, this data can be parsed into a tag header 0102 (corresponding to the field tag), a tail 0d0a, and 12345.
Converts the data into a corresponding memory block and copies the data into the corresponding memory block with the structure of
Head:Uint16
Text:Byte[5]
