iBeacon
DevCamp
iBeacon is a new technology that extends Location Services in iOS
iBeacons provide a way to create and monitor beacons that advertise certain identifying information using Bluetooth
low energy wireless technology
(ref iOS 7 Understanding Location Services - Apple)

Background mode
DevCamp
Background region monitoring
If a region boundary is crossed while an app isnrsquot running that app is relaunched into the background to handle the event
In iOS regions associated with your app are tracked at all times including when the app isnrsquot running
Similarly if the app is suspended when the event occurs itrsquos woken up and given a short amount of time (around 10 seconds) to handle the event
When necessary an app can request more background execution time using the beginBackgroundTaskWithExpirationHandler method of the UIApplication class
DevCamp
buthellip
Region monitoring in background takes very long time to notify the region change (up to 15min)
there is a little trick
Set the notifyEntryStateOnDisplay to YES
the location manager sends beacon notifications when the user turns on the display and the device is already inside the region These
notifications are sent even if your app is not running
DevCamp
Limitations
1 Signal interference2 Very small data packets3 Easy to sniff advertising packets 4 Easy to clone a beacon

Background region monitoring
If a region boundary is crossed while an app isnrsquot running that app is relaunched into the background to handle the event
In iOS regions associated with your app are tracked at all times including when the app isnrsquot running
Similarly if the app is suspended when the event occurs itrsquos woken up and given a short amount of time (around 10 seconds) to handle the event
When necessary an app can request more background execution time using the beginBackgroundTaskWithExpirationHandler method of the UIApplication class
DevCamp
buthellip
Region monitoring in background takes very long time to notify the region change (up to 15min)
there is a little trick
Set the notifyEntryStateOnDisplay to YES
the location manager sends beacon notifications when the user turns on the display and the device is already inside the region These
notifications are sent even if your app is not running

iBeacon is a new technology that extends Location Services in iOS
iBeacons provide a way to create and monitor beacons that advertise certain identifying information using Bluetooth
low energy wireless technology
(ref iOS 7 Understanding Location Services - Apple)

Background region monitoring
If a region boundary is crossed while an app isnrsquot running that app is relaunched into the background to handle the event
In iOS regions associated with your app are tracked at all times including when the app isnrsquot running
Similarly if the app is suspended when the event occurs itrsquos woken up and given a short amount of time (around 10 seconds) to handle the event
When necessary an app can request more background execution time using the beginBackgroundTaskWithExpirationHandler method of the UIApplication class
DevCamp
buthellip
Region monitoring in background takes very long time to notify the region change (up to 15min)
there is a little trick
Set the notifyEntryStateOnDisplay to YES
the location manager sends beacon notifications when the user turns on the display and the device is already inside the region These
notifications are sent even if your app is not running
DevCamp
Limitations
1 Signal interference2 Very small data packets3 Easy to sniff advertising packets 4 Easy to clone a beacon

Background region monitoring
If a region boundary is crossed while an app isnrsquot running that app is relaunched into the background to handle the event
In iOS regions associated with your app are tracked at all times including when the app isnrsquot running
Similarly if the app is suspended when the event occurs itrsquos woken up and given a short amount of time (around 10 seconds) to handle the event
When necessary an app can request more background execution time using the beginBackgroundTaskWithExpirationHandler method of the UIApplication class

buthellip
Region monitoring in background takes very long time to notify the region change (up to 15min)
there is a little trick
Set the notifyEntryStateOnDisplay to YES
the location manager sends beacon notifications when the user turns on the display and the device is already inside the region These
notifications are sent even if your app is not running

Background region monitoring
If a region boundary is crossed while an app isnrsquot running that app is relaunched into the background to handle the event
In iOS regions associated with your app are tracked at all times including when the app isnrsquot running
Similarly if the app is suspended when the event occurs itrsquos woken up and given a short amount of time (around 10 seconds) to handle the event
When necessary an app can request more background execution time using the beginBackgroundTaskWithExpirationHandler method of the UIApplication class

Region monitoring in background takes very long time to notify the region change (up to 15min)
