Before you start

  • When the Intervalometer app first starts, allow Bluetooth access so it can discover and connect to your G7 X Mark III.
  • Allow the app to use location / localisation services when prompted. On many phones this permission is required by the operating system to scan for nearby Bluetooth devices, even though the app does not use your location for tracking.
  • The G7 X Mark III uses a combined Wi-Fi/Bluetooth connection flow. Bluetooth pairing is set up through the Wi-Fi/Bluetooth connection menu accessed by pressing the dedicated wireless button.
