Listen to keypress in HTML/JavaScript on iOS/Safari with Bluetooth Scanner/Keyboard without having to focus a field

I have the following setup:

  • iPad with Safari browser running a webb-application.
  • Bluetooth barcode-scanner connected/paired with the iPad.

My web-application listens to keypress events globally which gives me the possibility to trigger scan functions without having the user to focus a textfield in the webb-application.

  • File transfer between android and iPhone via bluetooth?
  • Keep bluetooth sound when initializing AVAudioSession
  • where is example of iOS Bluetooth LE peripheralManager didReceiveWriteRequests
  • Gimbal beacon discovery
  • Bluetooth LE app, how to build it cross-plaftorm (iOS-Android)?
  • GameKit keeping connection going while device screen off or in background
  • The above works fine when running the application on a desktop with an USB-scanner.

    My problem is that the application doesn’t trigger keydown(press/up) events until a textfield is focused on the iPad when the bluetooth-scanner is connected.

    Is it possible to achieve?

    A related question from a while ago:
    How can I add a Javascript listener to capture input from bluetooth barcode scanner to iPad?

    Thanks /E

    I believe that with mobile Safari (and most other iOS mobile browsers), keypresses are only detectable by the web app when a form input is infocus. Your device (without an external keyboard) can’t take keypress input without a form input being selected simply because the keyboard would not be up.
