# Enhanced MikroTik CAPsMAN Auto-Provision Script
# This script is created to address a bug in MikroTik CAPsMAN (version 7.16.2) where
# the 'reselect interval' for automatic channel selection does not function as expected.
# The script ensures access points (CAPs) reselect channels at different intervals to 
# avoid overlapping channel selection due to simultaneous scanning at startup.

# Define scheduler name and intervals
:local schedulerName "auto_provision"
:local shortInterval "00:01:15"
:local mediumInterval "00:11:15"
:local longInterval "01:11:15"
