autoClose
Boolean
Specifies whether LINE should disconnect from the device after any scenario in the scenario set finishes running. If false
, the connection is maintained. Pay careful attention to the values you use for these parameters. See also Important notes related to using automatic communication in the LINE Things documentation.
suppressionInterval
Number
If autoClose = true
, this specifies the time (in milliseconds) before LINE should try to reconnect to the device after automatic disconnection. Reconnecting after the specified interval is not guaranteed to work. Depending on the environment in which LINE is running, the reconnection time may vary significantly. If
autoClose = false
, set this to 0
.
