Hi zz_zhang,
The "bluetooth-central" keyword gives the application the right to handle
Bluetooth specific events while in the background. It does not give the app a
generic permission to run in the background. Meaning, NSTimers will not work
when the app is in the background.
Thanks,
Joakim
Hi,
How to scan BLE device in
background?
I schedule a NSTimer to
call scan function. But the timer event is not called when app in the
background.
I have added the "bluetooth-central" to UIBackgroundModes in the app's info.plist. And my app
run well in background when receives a notificaion form
peripheral.
Thanks advance.
