■BMI Mode

While the scale is used in BMI mode, the output data will vary depending on the form of the received data.

aWhen receiving 4 bytes of data, as indicated in 1-1, the scale will calculate your BMI using the currently input height figure, and 26 bytes

of data will be output, as indicated in 2-1 or 2-2, depending on the measurement unit.

bWhen receiving 11 bytes of data, including measurement units and height figures, in the form indicated in 1-2 or 1-3, the scale will calculate your BMI using these figures, and 26 bytes of data will be output, as indicated in 2-1 or 2-2, depending on the measurement unit.
