BLE Beacon doesn't wake the app in background when screen is turned off

Question

I'm developing an application that communicates with a BLE device and for the purpose of the app, a Beacon (Eddystone) has been implemented in the BLE device.

In my application I implemented all the codes for Beacon recognition. Everything is working properly. When the application is terminated , iOS recognizes the Beacon and wakes up my application to execute code.

To verify that the code executes correctly I trigger local notifications at certain stages of the code executed by the wake up of the Beacon.

I receive all my notifications correctly and when I lock the screen and the screen turns off, it always works without problems. Notifications are for testing only, but in the Production environment there will be no notifications.

My Problem:

When I'm in Production mode (without local notifications)

1. App is terminated & screen is locked + turned ON = Code executes successfully
2. App is terminated & screen is locked + turned OFF = Beacon doesn't wake the app - nothing happens

What can be the reason? Are there any limits to using the Beacon? iOS does not listen to the Beacon when the screen is off?

NOTE:

1. Location permission is set to Always allow .
2. The Beacon used is Eddystone and not iBeacon - Can it be the reason?

Thank you very much! :)

尝试将CLbeaconRegion的notifyOnExit属性设置为true。
