We integrate with a lot of different devices and sensors, some Bluetooth and others ANT+. Bluetooth sensor and device connections are only available for iPhone 4S and above, as well as any Android phone with at least OS 4.3 and Bluetooth Smart capabilities. For general instructions on pairing a heart rate monitor or device see our How to Connect Bluetooth Sensors help article.
If you're having trouble connecting your device, the best option would be to follow the instructions below. This should help you reconnect any sensors or workout devices (especially Bluetooth) including heart rate monitors, stride sensors, speed & cadence sensors, and power meters.
- Ensure your device has Bluetooth turned on.
- If a sensor will not connect after confirming Bluetooth is on, navigate to the applicable sensor in your "Connect Apps and Devices" section of the MapMy app menu and tap "Forget Paired Sensor" (if the device has never been paired, or is not listed here, disregard this step for now).
- Next, visit your iOS or Android Bluetooth settings and forget the same Bluetooth device from your phone's settings as well.
- Make sure your sensor is in pairing mode. Usually this can be done by turning the device completely off, then turning it on and holding the power button until (usually) a light on the device or some other audio or visual prompt will indicate it's in pairing mode. Note, there usually isn't an indication of entering pairing mode for chest-strap heart rate monitors.
- Attempt to pair your sensor again, but directly from the MapMy app. It could take a minute or two.
- If this doesn't work, restart your phone (and the sensor itself if possible) and retry the above steps. Often this step should fix any problems with your phone itself miscommunicating with the Bluetooth frequency and allow the sensor to be picked up.
- Finally, delete and reinstall the app from the app store, which will both ensure you're using the latest version and should clear any temporary files and cache that may have caused this problem.
Additionally, if using a heart rate chest strap, ensure the coin cell battery isn't low or dead. CR2032 coin cell batteries tend to last between three and six months of normal use (1hr per day), but the battery can be drained more quickly if the strap is accidentally turned on (via contact with metal or water) and searching for HR when it's not in use.
A final note, if your activity does not record full heart rate data on an iPhone, you may need to ensure MapMy has access to your location and background functionality. If this is turned off you will also have incorrect GPS recordings most likely.
