Before you start

  • When the Intervalometer app first starts, allow Bluetooth access so it can discover and connect to your EOS R100.
  • 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.

    Press the MENU button and navigate to [Wireless settings: Wi-Fi/Bluetooth connection].

After pairing

Once the connection is established, you can start and stop exposures from your phone without touching the camera.

  • Set exposure time and interval directly in the app.
  • Use BULB mode on the camera and let the app control how long each exposure runs.
  • Run an open-ended sequence or stop automatically after a chosen number of images.
  • Use the Bluetooth link to minimise camera shake when starting and stopping exposures.

Cancel pairing and start again

If you change phones or run into connection problems, delete the existing pairing and set it up again.

On the EOS R100

  1. Press MENU and navigate to [Wireless settings: Wi-Fi/Bluetooth connection] → [Connect to smartphone].
  2. Select [Edit/delete device].
  3. Choose the smartphone to remove.
  4. Select [Delete connection information] and confirm with [OK].

On the smartphone

  1. Open your phone's Bluetooth settings.
  2. Find the entry for your EOS R100 and remove or forget the device.

After removing the pairing on both camera and phone, follow the steps in the pairing section above to connect the Intervalometer app again from scratch.

Troubleshooting

Phone cannot find the camera

  • Make sure the camera is on the pairing screen after selecting [Pair via Bluetooth] and pressing the Quick Control/Set button.
  • Check that Bluetooth is enabled on your smartphone and that the EOS R100 Bluetooth setting is set to [Enable].
  • If the camera still does not appear, cancel pairing on both camera and phone, restart both devices, and try again.

Camera shows a different smartphone name or will not pair

  • On the camera, open [Wireless settings: Wi-Fi/Bluetooth connection] → [Connect to smartphone] and use [Edit/delete device] to delete any smartphones you no longer use.
  • On your phone, remove old EOS R100 entries from the Bluetooth device list.
  • Repeat the full pairing process, including tapping Add new camera in the Intervalometer app.

Intervalometer app does not connect, but the camera shows a paired phone

  • Ensure no other app is trying to control the camera in the background. If you use Canon's own remote control app, close it completely before using the Intervalometer app.
  • In the Intervalometer app, tap your camera entry or use the reconnect option to establish the Bluetooth link again.
  • If the problem persists, delete the pairing on both camera and smartphone (as described above) and set it up again from scratch.

Camera shows "Connection target not found"

  • On the camera, remove the existing phone entry under [Wireless settings: Wi-Fi/Bluetooth connection] → [Connect to smartphone] → [Edit/delete device] by selecting your phone and choosing [Delete connection information].
  • On your phone, open Bluetooth settings and remove / forget the EOS R100 entry.
  • Start the pairing process again from the beginning and, in the Intervalometer app, use Add new camera to scan for the EOS R100 and add it as a new device instead of tapping connect on an old entry.
