Bluetooth LE Device scan in background from iOS

Question

I am working on to scan BLE in Background mode.

Issue is not working in Background scan. Its working very fine in Foreground mode.

Below is

Answer 1

You cannot scan for nil services in the background - you must specify the service(s) that you are interested in. From the documentation

Apps that have specified the bluetooth-central background mode are allowed to scan while in the background. That said, they must explicitly scan for one or more services by specifying them in the serviceUUIDs parameter.

Answer 2

For your app to continue to receive Bluetooth updates in the background, you need to add a UIBackgroundModes entry to your Info.plist and include the value bluetooth-central in the list.
