Device Details

• Device: Taylor Smart
• Model: Taylor Smart Scale
• Firmware: 3.8
• Technology: Bluetooth LE

Custom Data Types

The Taylor Smart Scale defines its custom data types in the following unit:

• Iot.Device.TaylorSmartScaleTypes

Taylor Smart Scale Response

The TTaylorSmartScaleResponse type returns the response to the request data, received from the Taylor Smart Scale.

• Value: Raw array of bytes received from the device.

Taylor Smart Scale Command

The TTaylorSmartScaleCommand type contains the command data to send to the Taylor Smart Scale.

• Value: Raw array of bytes to be sent to the device.

Taylor Smart Scale Measurement

The TTaylorSmartScaleMeasurement type returns the user measurements from the device.

• Value: Raw array of bytes received from the device.
• PresentProperties: Set of properties in the measurement.
  • Possible values are: Impedance1, Impedance2, MeasurementStatus, Timestamp, UnitSystem, UserNumber, Weight
• UnitSystem: Preferred user unit system:
  • 0: Kilograms.
  • 1: Pounds.
  • 2: Stones.
• Weight: Weight measurement returned from the device, in the selected UnitSystem.
• Timestamp: UTC Timestamp value when the measurement was taken.
• Impedance1: First feet impedance value from the Taylor Smart device measurement.
• Impedance2: Feet impedance value from the Taylor Smart device measurement.
• UserNumber: User profile number of the measurement.
• MeasurementStatus: Measurement reliability status.

Taylor Smart Scale Append Measurement

The TTaylorSmartScaleAppendMeasurement type returns the estimated body composition measurements from the device.

• Value: Raw array of bytes received from the device.
• PresentProperties: Set of properties in the measurement.
  • Possible values are: BasalMeta, Battery, BodyFat, BodyWater, BoneDensity, MuscleMass, Timestamp, UserNumber, VisceralFat
• Timestamp: UTC Timestamp value when the append measurement was taken.
• UserNumber: User profile number of the measurement.
• BasalMeta: The estimated calories of the measurement.
• BodyFat: Percentage body fat value.
• BodyWater: Percentage of the total body water in the body.
• VisceralFat: Percentage of the visceral fat.
• MuscleMass: Total muscle mass percentage estimation.
• BoneDensity: Percentage of the total bone density calculated from the measurement.
• Battery: Battery level of the device.

Device Specific Information

• Pairing: Press and hold the button on the back of the scale to start Bluetooth and initiate the pairing mode. This mode allows you to retrieve information (serial number, hardware revision etc.) and to set a personalized broadcast name. If you define the BroadCastName const, pairing is optional.
• Measuring: Press SEL on the scale, select a user and weigh yourself to start Bluetooth.
• Be sure BroadCastName const has a correct value. To get the BroadCastName and DeviceName, run a Bluetooth scanner. You can deploy the BLEScanner demo project found in the Samples directory (\Samples\Object Pascal\Multi-Device Samples\Device Sensors and Services\Bluetooth\BLEScanner).

Here is an example of what you are looking for:

Mode	BLEScanner	Const
PAIR	113193	DeviceName: string = '13193'; BroadCastName: Does not apply
MEASUREMENT	013193C39C74D1	DeviceName: string = '13193'; BroadCastName: TBytes = [$C3, $9C, $74, $D1]
