Longer sampling rate does not save that much energy as expected. Also refer to this [1].
Omgps uses fixed 1Hz send rate for now, but ever tested a lot (even FIXNOW) before release. Incoming version will support configuring sampling rate which is implemented by sleep(). During my last trip (mountain climbing), we were told at hotel that the mountain is difficult to climb, almost no way. I did a quick hacking: To help find back way upon get lost, current position is displayed on track replay; To save a bit energy, sampling rate was increased to 5 seconds For next mountain climbing, I bought two Nokia BL-5C batteries yesterday :) [1] http://n2.nabble.com/test-result-of-battery-current-against-display-brightness-and-GPS--power-mode-tp2541178p2541178.html jeremy jozwik wrote: > > omgps does it. and tracks well too > > On Fri, Jul 10, 2009 at 1:13 PM, Petr Vanek<van...@penguin.cz> wrote: >> the wiki mentions ]1[ how to increase the sampling rate of gps, is >> there a way to lower it to save energy during gps tracking that >> doesn't require such precision? >> >> Petr >> >> >> ]1[ >> http://wiki.openmoko.org/wiki/Neo_FreeRunner_GPS#Configuration_for_a_higher_sampling_rate >> >> >> _______________________________________________ >> Openmoko community mailing list >> community@lists.openmoko.org >> http://lists.openmoko.org/mailman/listinfo/community >> > > _______________________________________________ > Openmoko community mailing list > community@lists.openmoko.org > http://lists.openmoko.org/mailman/listinfo/community > > -- View this message in context: http://n2.nabble.com/lowering-gps-sampling-rate-tp3240723p3241085.html Sent from the Openmoko Community mailing list archive at Nabble.com. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
