Shazron Abdullah edited comment on CB-12846 at 6/3/17 1:32 AM: --------------------------------------------------------------- The core itself does not continue executing endlessly (there is no event polling) - it is triggered to pull in commands by JavaScript sending a gap:// url when a command is sent back. There is one timer here that gets cleared: https://github.com/apache/cordova-ios/blob/master/CordovaLib/cordova.js#L1016-L1031 I couldn't possibly repro this exactly - You could try profiling your app in Safari Web Inspector to see what's going on. was (Author: shazron): The core itself does not continue executing endlessly (there is no event polling) - it is triggered to pull in commands by JavaScript sending a gap:// url.

As expected, my app is allowed > to run for 10 seconds in the background with the [bluetooth-central > UIBackgroundMode|https://developer.apple.com/library/content/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html]. > Once the necessary processing is completed, the JS event loop runs until the > 10-second window closes. Because beacon sightings happen as frequently as > several per second, the app runs in the background constantly, killing the > user's battery. I can setInterval() in JS with a 1000ms interval and it runs > successfully every time; my Angular app runs $digest cycles in the background > which are unnecessary and quite expensive. > I think I need a way for the native plugin code to relinquish execution and > return the app to the background. > StackOverflow: > [https://stackoverflow.com/questions/44145031/stopping-background-javascript-activity-on-location-triggered-bluetooth-central] -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@cordova.apache.org For additional commands, e-mail: issues-h...@cordova.apache.org
