Detecting trigger from selfie stick (Bluetooth keypress) on IOS and Android

Hardware (GPS, accelerometer, etc.)
#1

This post is archived, or I would have asked there: https://forums.coronalabs.com/topic/42289-identify-volume-button-pressed-on-ios-possible/

  • What we’d like to do is receive a keypress, any keypress.

  • One way to get a keypress is to pair a Bluetooth device.

  • Selected wireless selfie sticks send keypresses over Bluetooth to take the picture.

  • On IOS, that keypress is Volume Up, which may cause a problem.

  • We’d like to do this in Corona, not with native code.

Is there a spec of what keypresses are detected by Corona, or more information about these types of triggers and selfie stick support?

If you are trying to access volume button you may be able to hack together a solution with my volume control plugin. You should loop and check if the volume is changed (up or down) and then change it back and take photo

Great, Scott :slight_smile: Should actually work. We’ll try it and report back!

Is there a way to prevent the volume pop-up from showing - like in the built in camera app? 

#5

Is there a way to read a keypress on IOS without showing the keyboard, like on Android?

This could remove the need for my last question above.
