# Notes:
# The miband4 does not (seem to) support different vibration intensities, rather the values sent (2-255)
# represent how long the vibration motor runs. A value of 30 roughly corresponds to 60ms of motor run time.
# Sending a value of 255 triggecd rs continuous vibration.
# Currently "continuous" mode doesn't work, as it doesn't turn off.
# This will be fixed shortly.
