One thing about bluetooth and phones that I really wish that apple/google/bluetooth group could resolve is a way for a device to advertise that it needs attention and then bubble that up to the nearest phone that is registered for that Service UUID.

The blog illustrates the feature of scanning bluetooth devices around you and pushing data to the cloud when needed, but right now that background scan is really not optimal for both ios and android. Android requires a manual scan process every 15 minutes or so based on background task intervals, and iOS only alerts you to ble scans when you turn on the screen of your phone. Android will cause you to burn battery constantly checking on devices, but iOS will cause you to miss them entirely unless you unlock your phone alot.

Right now we have a simple use case of updating the clocks on our devices that would be a whole lot easier if the devices could simply advertise they need attention after XX hours, and that ran a background service for our app to do it when needed, and avoid the whole periodic scanning.
