Ticket #350 (closed enhancement: invalid)

gps - deferred shutdown

Reported by: vanous Owned by: daniel
Priority: minor Milestone: milestone5.5
Component: framework/ogpsd Version:
Keywords: Cc:


When process requests GPS device via frameworkd, after release it is mediately released (AFAIK). Would it be possible to introduce a delay when the device would be still held say for several seconds (perhaps as global setting available via framwork).

Why: If user closes one gps app and starts another (or needs an app restart), gps looses fix and it is necessary to wait for a new fix and if this happens during high speed or in another unfavorable conditions getting new fix might be quite hard...

As a workaround you could open the second app and only then close the old one.

To improve TTFF we need to either fix uploading ephemeris or use FixNOW (see #47).

I'm not sure whether we really want that. We should not introduce multiple methods to deal with resources. I'd rather see you explicitly setting the resource policy to 'Enabled', if you plan to work with multiple GPS apps.

On a related note, on the Neo we now have superfast fixes again, so it shouldn't be a problem.

I'm closing this as INVALID for now, but lets revisit if we see fit.
