  timeouts: initial fast advertising mode, slow advertising mode, and an optional
  delay to stop advertising entirely. Values can be set in multiples of timeout
  ticks (0.625ms per unit) or in ms (approximate since it gets converted to 0.625ms
  units). The optional timeout to stop advertising entire is set via the
  .start(timeout) parameter.
