Run iPhone as an iBeacon in the background

Question

Is it possible to run an iOS 7 device as a Bluetooth LE peripheral (iBeacon) and have it advertise in the background? I have been able to get it to advertise in the foregro

Answer 1

I am also hoping to be able to set up my (test) app to advertise an iBeacon from the background. The docs on the UIBackgroundModes info.plist key suggest that the bluetooth-peripheral key might work, but it seems that it doesn't. (I just tested it a few minutes ago.)

What I'm doing for now is setting the idle timer to disabled, as RawMean suggests, and then setting the screen brightness to 0. Finally, when my test app is acting as an iBeacon, I add a shake event handler that lights the screen up again for 30 seconds. Dimming the screen as low as it will go helps reduce battery drain somewhat.
