I am willing to be able to make my UP3 vibrate at will. I cannot find in the API documentation how to achieve it.

A workaround that comes to my mind is eventually adding a task schedule from the apps for the minute after, well, a nicer solution might exist.

Thanks!

The Developer APIs for UP do not expose a way to trigger band vibration.

There are several reasons to keep this feature private. Here are a few examples:

  1. Band vibration can reduce battery life if triggered too frequently.
  2. App-triggered band vibration would require a data sync from the phone to the band, and the band is not always guaranteed to have a bluetooth connection (e.g., the phone could be out of range).
  3. Developer application events are not necessarily occurring in real time, so a band vibration in response to an event could occur much later than the event and create a disjointed user experience.
