Note:

The last two bytes in a command shown as “nn 00” specify the 16-bit data size in the order of “LowByte HighByte.” For example a two-byte data size

would be specified as “02 00.” The sensor will not provide more bytes than the number requested in the command, but it will only supply up to a

maximum of 8 bytes at a time. The sensor will re-send the last packet if the transfer is not acknowledged properly.
