A Biometric Sensor is an external hardware device that connects to the Strava Android app to provide additional performance data for the Strava activity recording process
- Compatible Sensors
- How to pair a sensor
The Strava Android app version 4.9 and later supports heart rate monitors, cadence sensors, and power meters.
- Bluetooth Low Energy: your phone must be running Android version 4.3 or greater and must be equipped with BLE sensors. We do not support Bluetooth 2.0.
- ANT+: your phone must be equipped with ANT+ technology or be able to use an ANT+ adaptor. In order to use an ANT+ USB adapter, your phone must be compatible with USB OTG (On The Go).
- We officially support Wahoo sensors, however, most other Bluetooth LE and ANT+ sensors should work.
How to Pair a Sensor
- Navigate to the Record screen, tap 'Settings' and select Sensors. You'll see the app "Searching for Bluetooth and ANT+ Sensors."
- If you pairing an ANT+ sensor you'll see the option: (x) Sensors Nearby
- Tap that option and follow the prompts.
- If you are required to install additional ANT+ services, you will need to do so in order to use ANT+ sensors. If you disabled your phone's pre-installed ANT+ services, they must be re-enabled in order to use ANT+ sensors.
- If you are using the USB adapter, make sure to check the box next to the "Use by default" message or else you will see this prompt every time you try to connect a sensor.
- Once your device has installed the software packages and you've proceeded through the prompts, you'll see the app "Searching for Bluetooth and ANT+ Sensors."
- When your sensor appears, tap the + icon to add the sensor.
- If you're pairing a Bluetooth LE sensor when your sensor appears, tap the + icon to add the sensor.
Searching for Sensors
The Strava Android app will search for new sensors any time the New Activity tab is selected, for up to 2 minutes. The app will first search for sensors it has already connected to (if there are any), then for any other sensors.
- The app prefers previously-connected sensors to new sensors. To forget old sensors, tap the (-) button next to the sensor you'd like to remove.
- The app will also initiate sensor searches when you visit the Biometric Sensors setting page. If it is already connected to a particular type of sensor it will not connect to new sensors of that type. In order to force searching for a particular sensor type, you can toggle that particular sensor off and on in the settings.
- When the Strava Android app is connected to sensors but does not receive data for several minutes it will indicate so by showing the sensor icons on a red background. This error state will persist until you reconnect to new sensors, for example by toggling individual sensors in the Biometric Sensors settings page, or when you start recording an activity.
Troubleshooting Connection Issues
- Try toggling Bluetooth off then on in your phone's settings.
- Check that the battery in your sensor is charged.
- Be careful that your Bluetooth device has not paired with another sensor that's within range. Bluetooth only allows you to pair with one device.
- It helps to generate data while paring the sensor, for example, wear your heart rate monitor.
Do you support speed and/or cadence data gathered from power meters?
The Strava Android app does not gather speed or cadence data gathered from power meters at this time.
Do you use the speed data gathered from speed sensors?
The Strava Android app does not use speed data gathered from speed sensors. Please see article: How Distance Is Calculated for more details.
How can I ensure I have a strong connection between my Android device and my Biometric Sensors?
The best way to ensure a strong connection is to provide an unobstructed path between your Android device and the Biometric Sensors to which you are connecting. Consider;
- Mounting your device where it will have an unobstructed path to your Biometric Sensors
- Putting your device in a jersey side pocket (rather than the center pocket).
Will Strava collect data from my footpod?
If you enable your phone's internal step detector and use a footpod, we’ll only use the data coming from the footpod. Samsung S5 users should note that their phone does not report step rate unless the screen is unlocked—this will significantly decrease battery life.
Where can I buy Biometric Sensors and/or adaptors that work with Strava?
Strava currently supports peripheral connectivity through the devices produced by Wahoo Fitness. iPhone models 4S and newer can leverage Wahoo's Bluetooth LE peripherals. This includes the Wahoo TICKR, the Wahoo RPM Cadence Sensor, and the ANT+ Key. Wahoo's ANT+ adapters will enable Strava to communicate with most 3rd party ANT+ heart rate monitors, cadence sensors, and power meters - including the Gamin Summit Heart Rate Monitor. Keep in mind that because it doesn't use Bluetooth LE, the ANT+ key will work with the iPhone 4 as well as the 4S.
The Polar H7 heart rate sensor and the Polar Stride Sensor footpod work when paired with an iPhone 4S or newer.
The Stages Bluetooth Power Meter is supported for use on Strava.
