5 months ago Hi @blood-romantic, can you share the whole class component? I want to know:
From what I checked, if you change permissions when the app is on the background this listener won't trigger the event - it will only work if the app is in the foreground.

If I disallow the blue tooth permission on the app, the onstatechange will never be triggered whatever the blue tooth on iPhone is toggled to PowerOn or PowerOff

export default connect(mapStateToProps, mapDispatchToProps)(ScanningScreen);As I mentioned, while you are in settings, your app is in background. It’s not possible to handle events in background as the app execution is stopped. If you want to handle this case you could use AppState and manually read the state when app enters the foreground
