Overview

Session objects control the FIT recording state machine.

Example:

Format for setting up a Session object

using Toybox.ActivityRecording;
var session = ActivityRecording.createSession({  // set up recording session
    :name=>"Generic",                            // set session name
    :sport=>Activity.SPORT_GENERIC,              // set sport type
    :subSport=>Activity.SUB_SPORT_GENERIC        // set sub sport type
});

Instance Method Details

addLap() as Lang.Boolean

Add a lap to the current recording.

Returns:

  • Lang.Boolean —

    true if a lap was successfully created, otherwise false

Since:

API Level 1.0.0

createField(name as Lang.String, fieldId as Lang.Number, type as FitContributor.DataType, options as { :count as Lang.Number, :mesgType as Lang.Number, :units as Lang.String, :nativeNum as Lang.Number }) as FitContributor.Field

Create a new Field.

Field objects allow developers to store information in FIT developer fields. This information can be displayed in Garmin Connect as a per-second graph, as lap information, or as workout summary information.

Parameters:

  • name — (Lang.String) —

    The name of the Field as a String

    • The maximum length may vary between products

    • At least 64 bytes are available

  • fieldId — (Lang.Number) —

    The unique Field Identifier for the Field

  • type — (FitContributor.DataType) —

    The type definition for the Field from the DATA_TYPE_* enumerator in the FitContributor module

  • options — (Lang.Dictionary) —

    Optional parameters that can be specified for Field creation

    • :count — (Lang.Number) —

      The number of elements to add to the Field if it is an Array

      • This is also the maximum combined size of strings plus null terminators if the type is DATA_TYPE_STRING (Default 1)

      • Apps are limited to 256 total bytes per message

      • Data fields are limited to 32 bytes per message

      • Messages larger than the limit will result in a "New Field out of memory for FIT data" error.

    • :mesgType — (Lang.Number) —

      The message type that this Field should be added to

    • :units — (Lang.String) —

      The display units as a String

      • This should use the current device language

      • The maximum length may vary between products

      • At least 16 bytes are available

    • :nativeNum — (Lang.Number) —

      If this Field can be treated equivalently to a Field that is included in the FIT SDK use this to indicate the Field Number that is specified by the FIT Profile.

discard() as Lang.Boolean

Complete the Session by discarding the recorded data.

Returns:

  • Lang.Boolean —

    true if the Session was successfully discarded, otherwise false

isRecording() as Lang.Boolean

Check if recording is active for this Session.

Returns:

  • Lang.Boolean —

    true if recording is active, otherwise false

save() as Lang.Boolean

Complete the session by storing the FIT file on the file system.

Returns:

  • Lang.Boolean —

    true if the session was successfully saved, otherwise false

Since:

setTimerEventListener(listener as Lang.Method(eventType as ActivityRecording.TimerEventType, eventData as Lang.Dictionary) as Void) as Void

Set the listener for Session timer events

The listener method is called whenever a new timer event occurs.

The keys in the Dictionary passed to the listener callback depend on the the value of the eventType parameter.

Parameters:

  • listener — (Lang.Method) —

    A reference to a callback which must accept two arguments.

    • eventType: A TIMER_EVENT_* enum that describes the event that occurred.

    • eventData: A Dictionary containing data relevant to the timer event or null. If eventType is TIMER_EVENT_LAP, the following are provided if available:

      • :elapsedDistance Float (meters)

      • :averageSpeed Float (meters/second)

      • :maxSpeed Float (meters/second)

      • :startTime Moment (Moment)

      • :elapsedTime Number (milliseconds)

      • :timerTime Number (milliseconds)

API Level 3.0.10

start() as Lang.Boolean

Begin recording a FIT file on the system.

Returns:

  • Lang.Boolean —

    true if recording was successfully started, otherwise false

Since:

API Level 1.0.0

stop() as Lang.Boolean
