iBeacon region monitoring unreliable

Number:rdar://29265623 Date Originated:2016/11/15
Status:Closed Resolved:
Product:iOS Product Version:10.1.1
Classification:Bug Reproducible:Sometimes

We are using iBeacon for our app to trigger events when entering or leaving the region of a specific iBeacon.

Steps to Reproduce:
App registers for monitoring iBeacon region with specific UUID, major and minor values.

Expected Results:
Every event of entering or leaving the region of the configured iBeacon should be fired and trigger the app.

Actual Results:
Sometimes it works as expected for some time but after some hours no events are triggered anymore.

iOS 10.1.1

When iBeacon monitoring stops working as expected it sometimes helps to do one of the following:
- Turn Wireless Networking Off/On
- Turn Bluetooth Off/On
- Reboot Device

Sometimes we get inside/outside region notifications when doing a phone call or when disconnecting from the car bluetooth connection - even when we were inside the iBeacon region the whole time.

iPhone 7
