ios - swift :信标测距在打电话时返回空数组

Question

我们有一个使用 CLLocationManager 进行信标测距的应用程序 - Swift 4 下的核心位置。测距功能通常工作正常，返回范围内的任何信标。但是，如果蓝牙耳机连接到手机，并且接听或调用电话，仍然会调用信标测距函数，但会返回一个空数组。我们的应用程序在前台时会发生这种情况。

尝试了 Apple 商店的信标扫描仪 (Beacon Scan) 应用程序。它还会在通话时停止检测信标。

我们期待信标测距在蓝牙耳机通话时继续返回检测到的信标。关于为什么没有的任何想法？退出区域事件也会被触发。当电话结束时，信标测距再次开始工作。这在 Android 上不是问题。

Answer 1

这是 Apple 的回应。显然，在使用蓝牙耳机通话时无法进行信标检测。

PLATFORM AND VERSION iOS We've tested with iPhones 6s (OS 12.3.1), 6s Plus (12.4), and 10r (12.4) using AirPods, Jabra and Plantronics headsets so far. All have this issue.

DESCRIPTION OF PROBLEM We have an app that does beacon ranging using CLLocationManager - Core Location under Swift 4. The ranging functions works fine, returning any beacons in range. However, if a Bluetooth headset is connected to the phone, and a phone call is either received or made, the beacon ranging function is still called, but returns an empty array. This happens with our app in the foreground.

Tried a beacon scanner (Beacon Scan) app from Apple store. It also stops detecting beacons when on a phone call.

We're expecting beacon ranging to continue returning detected beacons while on a Bluetooth headset phone call. Any ideas as to why it doesn't? The exit region event also gets triggered. When the phone call ends, the beacon ranging starts working again.

STEPS TO REPRODUCE Implement a beacon detection solution using Core Location. Or, install a beacon scanner app. Connect phone to a Bluetooth headset. While ranging beacons with a beacon on, make or receive a phone call via the Bluetooth headset. Beacon detection fails while on the call. As soon as the call is over, beacon ranging once again returns the filled array.
