temporary suspending providers

[Stefan Kost]

hi,

is there a way for clients to tell that they don't need position updates
for a while? If there is no active client the providers could suspend
/be suspended to save energy.

Apps could use that mechanism when they are in the background or when
they detect from an accelerometer that we are not moving.

Or is the idea that smart sources would adjust there signal interval
based on speed. Like if a GPS does not get a new position
(delta<epsilon) it would increase the update interval.
