My Bluetooth sensor is not connecting or not showing data, what do I do?

The most common reason for a Bluetooth sensor not connecting to Cadence is because it’s already connected to another device or app. Please make sure you’ve removed your sensor from any other devices and apps before connecting in Cadence, unless otherwise noted below.

If you’ve followed the steps below and are still having trouble, please don’t hesitate to email support@getcadence.app.

Depending on the manufacturer, Bluetooth devices can take awhile to wake up and connect. After waking them up (by putting a heart rate monitor on, spinning a wheel or pedal, etc.) please give them at least 30 seconds to connect.

For Garmin speed and cadence sensors in particular: please try connecting your Bluetooth sensor in the Garmin Connect app before connecting it in Cadence.

If your heart rate monitor, speed and cadence sensor, power meter, or other supported device isn’t connecting or being recognized, please try the following:

If the sensor isn’t showing up when scanning to add it to Cadence:

1. Remove the sensor in any other apps or devices you may have connected it in.
   • Once removed, try adding it again in Cadence. If it still doesn’t show up, continue…
2. Verify Cadence has permission to access Bluetooth.
   1. iOS: open the main Settings app, tap Cadence, make sure Bluetooth is turned on.
   2. Android: tap and hold the Cadence app icon, choose App Info, tap Permissions, make sure Bluetooth or Nearby Devices is allowed.
3. Make sure the sensor isn’t connected to your phone in the main Settings or Bluetooth apps. It should only be connected inside Cadence.
4. If possible remove the battery in the sensor for a couple minutes to ensure it resets.
5. Turn Bluetooth off and back on on your phone.
6. Reinstall the battery in the sensor and move it around so that it starts sending data and trying to connect again
7. Go to “Add new sensor” in Cadence and see if it shows up to connect. If it doesn’t, cancel the scan and tap “Add New Sensor” again a couple times just to be sure.
8. If you’ve followed these steps and are still having trouble, please don’t hesitate to email support@getcadence.app.

If the sensor is connecting in Cadence but not showing any data on the sensors screen or during an activity:

1. Trying disconnecting and reconnecting the sensor in Cadence.
2. Try connecting sensors in a different order, ie the one you’re having trouble with, try connecting first, and then add the other sensors.
3. If the data field never switches from “N/A” to a real value while you’re moving the sensor, try resetting your Bluetooth settings:
   1. Remove sensors from the Cadence app.
   2. Quit the Cadence app.
   3. Open the main Settings app on your phone and find the option to “Reset Network Settings”.
   4. Open Cadence and add the sensor again.
4. Make sure the data field that’s showing values on the Bluetooth Sensors screen is set as “Selected”.
   
5. Go back to the Computer screen to verify data values begin showing up.
6. If you’re still having trouble, please don’t hesitate to email support@getcadence.app.
