Bluetooth Extension

The Bluetooth Extension is an optional feature that improves Wi-Fi performance by automatically disabling Bluetooth when Shutter connects to your camera.

Why It Helps

iPhone shares a single antenna for Bluetooth and 2.4 GHz Wi-Fi. When both are active at the same time, they interfere with each other. Disabling Bluetooth while connected to your camera results in:

  • Faster live view streaming
  • Less lag when adjusting controls
  • Even 3x faster photo imports

How to Set It Up

  1. Open Shutter.
  2. Tap Set up Bluetooth Extension at the top of the screen, or go to Support tab > Bluetooth Extension.
  3. Follow the prompts to set up the Apple Shortcuts automation.

When Bluetooth Extension is not installed, the set up instructions will appear on the home screen.

Once configured, Shutter will automatically disable Bluetooth when it connects to your camera and re-enable it when you disconnect.

Important Notes

  • While Bluetooth is off, your Apple Watch won’t be connected. If you want to use the Watch app as a remote, don’t use the Bluetooth Extension. See the Apple Watch section for details.
  • AirPods and other Bluetooth accessories will disconnect while the shortcut is active. They reconnect automatically when Shutter disconnects from the camera.
