Apple App Store Requirements

If you build an app for any Infinite Peripherals device and are going to distribute your app on the App Store, you will need to register the app with Infinite Peripherals in order to obtain MFi Authorization.

You can do so through the Infinite Peripherals website. Infinite Peripherals will provide you with an identification number (PPID) that you have to include in review notes when submitting your app. Select "Yes" for the "Bluetooth feature" option when registering your app as some of the supported devices use Bluetooth with a non-standard profile for communication. This should be performed only once for all LineaInfinea devices.

App Developer Key

• Create an account at Infinite Peripherals developer portal
• After you account is approved you can create an app developer key in your main profile page
• Bundle ID Name for your generated key has to be the same as the bundle id of your app
• Before you use any Linea or Infinea device you have to first call:
  Gonector_Set("appDevKey" ; "LineaInfinea" ; "<your app dev key>")
