Ensure Location Services are on
Bluetooth connections on Android currently require Location Services to be enabled. Please check your system settings.
Ensure all app permissions are granted
Bluetooth connections on Android require the location permissions to be granted to the Wahoo app. Please ensure all permissions are granted in the system settings (Android Settings > Apps > Fitness > All permissions enabled).
Ensure battery optimizations are disabled for the app
Android phones running Android 6.0 or later will kill background apps automatically in certain circumstances. This may affect workout recording and/or device and sensor connectivity. Please ensure the Wahoo app is excluded from Android's "battery optimization" list. Note that some Android devices refer to this as "unmonitored apps" under battery settings.
Pair with the app, not the Android Bluetooth Manager
Wahoo devices should be paired with the Wahoo app, not the Android Bluetooth manager in the system settings. Make sure the device is not paired with the Android Bluetooth settings, then retry pairing from the Wahoo app.
Important: This does not apply to the TIMEX watch series devices as these devices must be paired with the system to function.
Ensure an exclusive connection
Wahoo devices are only able to maintain one Bluetooth connection at a time. Ensure other apps (including apps on other phones) are disconnected from your Wahoo device. Disable Bluetooth on any previously paired phone and force close any background apps which have previously paired to guarantee they are not maintaining a connection.
Forget and re-discover
Please try ‘forgetting’ the saved device in the Wahoo app and re-discovering.
Check for interference
Wifi can sometimes interfere with Bluetooth connections. Try disabling WiFi and connecting to the Wahoo device again. Move away from WiFi, Bluetooth, and other signals/devices which can cause interference like Chromecasts, GoPros, and power lines. For further potential sources of interference, see Signal Dropouts on the KICKR or Snap.
Check for background Bluetooth sync features from other apps
It has been observed that apps that have background Bluetooth sync features such as FitBit and Pebble can interfere with a stable Bluetooth connection, please disable all background Bluetooth features on apps like these.
Toggle Bluetooth
Turn off Bluetooth in the Android system settings for 30 seconds, then turn it back on. If Bluetooth does not switch off and on properly, reboot your mobile device.
Reboot
Try rebooting your Android device and, if possible, the Wahoo device. For Wahoo Smart Trainers ensure you disconnecting the power for 30 seconds.
Reset Android Bluetooth app
In the Android system settings, go to the Apps section and tap the 3 dots in the top right corner to select "Show system" and find the "Bluetooth" or "Bluetooth Share" app. Tap "Storage" and "Clear Data" on these apps to reset them, then reboot.
Try to connect with other Bluetooth apps
You can test your Bluetooth connection using the nRF Connect and SweetBlue Toolbox apps, available on the Google Play Store. If you cannot connect using these apps, the problem is likely with your phone, rather than the Wahoo app. We recommend raising a support ticket with your phone manufacturer.
