Connecting Canon EOS R5 to the Intervalometer App

Step-by-step instructions for pairing your Canon EOS R5 with the Intervalometer for Canon app over Bluetooth.

App Store

Google Play

Before you start

When the Intervalometer app first starts, allow Bluetooth access so it can discover and connect to your EOS R5.
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 EOS R5 requires Wi-Fi settings and Bluetooth settings to be enabled separately before pairing is possible. Steps 1 and 2 below cover this. If these are already enabled on your camera, you can skip straight to step 3.

Pair the EOS R5 with the Intervalometer app

Enable Wi-Fi settings.
Press the MENU button and navigate to [Wireless features: Wi-Fi settings]. Select [Enable].
Enable Bluetooth settings.
Still in Wireless features, select [Bluetooth settings] and set it to [Enable].
Open the Wi-Fi/Bluetooth connection menu.
Select [Wi-Fi/Bluetooth connection].
Select Connect to smartphone.
Select [Connect to smartphone].
Add a new device.
Select [Add a device to connect to].
Skip the QR code.
A screen shows app installation options. Because you already have the Intervalometer app, select [Do not display] to skip the QR code.
Select Pair via Bluetooth and start pairing.
Select [Pair via Bluetooth], then press the SET button to begin pairing. The camera enters pairing mode.
Open the Intervalometer app on your phone.
Unlock your phone and start the Intervalometer app for Canon.
Tap "Add new camera" in the app.
In the main control screen, tap the camera icon in the top-right corner labelled Add new camera.

The app now scans for nearby Bluetooth devices and lists available cameras.
Select your EOS R5 from the list.
When your camera appears, tap the entry that matches your EOS R5 to start pairing.
Confirm Bluetooth pairing on the phone.
Your phone shows a Bluetooth pairing request. Confirm the request to allow the Intervalometer app to connect to the EOS R5.
Confirm pairing on the camera.
Select [OK] on the camera screen and press the SET button to complete pairing.
Start using the Intervalometer app.
Pairing is complete. Your EOS R5 is listed as the active camera in the Intervalometer app, and the main control screen is ready to trigger the shutter.

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 R5

Press MENU and navigate to [Wi-Fi/Bluetooth connection] → [Connect to smartphone].
Select [Edit/delete device].
Choose the smartphone you no longer want to use.
Select [Delete connection information] and confirm with [OK].

On the smartphone

Open your phone's Bluetooth settings.
Find the entry for your EOS R5 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 in pairing mode (after selecting [Pair via Bluetooth] and pressing SET) and that both Wi-Fi settings and Bluetooth settings are set to [Enable].
Check that Bluetooth is enabled on your smartphone.
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, navigate to [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 R5 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 and set it up again from scratch.

Camera shows "Connection target not found"

On the camera, remove the existing phone entry under [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 R5 entry.
Start the pairing process again from the beginning and, in the Intervalometer app, use Add new camera to scan for the EOS R5 and add it as a new device.
