1. The data is returned as a list of numbers separated by carriage returns.
•accuracy
is a number that represents a distance in meters. The default value for accuracy
is 100 meters.
•timeout
is a number that represents the longest time (in seconds) it will take to get the data. The default value for timeout
is 10; the maximum value is 600.
•The default value for forPastSeconds
is the number of seconds since midnight.
•FileMaker Go returns an empty string if the sensor is not available for the device.
•The values for location
are the same as for the Location function.
•The values for locationValues
are the same as for the LocationValues function.
GetSensor ( "stepCount"; 3600 )
returns 8000 if the user has taken 8000 steps in the past hour.
