Before you start

  • When the Intervalometer app first starts, allow Bluetooth access so it can discover and connect to your G5 X Mark II.
  • 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 G5 X Mark II uses a Bluetooth pairing flow through the Wireless communication settings menu, accessed via the Set-up tab.
