Troubleshooting Heart Rate Monitor And Bluetooth Issues

If you own a heart rate monitor (HRM) with Bluetooth 4.0 (Smart) capacity, you can use it to record your heart rate while tracking with the Runtastic app. Instructions on how to connect your device can be found here.

As there are many devices on the market from various manufacturers with different specifications, we cannot always guarantee that your device will work flawlessly with the app. However, the following tips will resolve many of the most common connection issues:

Minimum Requirements:

  • Your phone: Android 5.0
  • Your heart rate monitor:  Bluetooth 4.0 capability (Smart)
  • Your Runtastic app: Latest version installed from the Google Play Store

Configure the following settings in your phone:

  • Make sure that bluetooth is turned on and that your phone screen is on
  • Close any background apps that may be using the sensor before connecting to the Runtastic app
  • Do not connect the HRM directly in your phone’s bluetooth settings. If it already is connected there, be sure to disconnect it: Settings > Bluetooth > tap the gear icon next to your HRM, and tap FORGET.
  • Connect the HRM in the Runtastic app via the Activity Setup icon next to the "Start" button followed by “Heart Rate”. More info here
  • If you cannot establish a Bluetooth connection between the HRM and your phone, please try the following: 
  1. Switch Bluetooth off and back on from your mobile device.
  2. Restart your mobile device. (Make sure you close out of all open apps before trying to reconnect)
  3. Disconnect and reconnect your HRM directly in the Runtastic app.

Make sure that the HRM itself is in good condition:

  • Check whether the battery of the device needs replacing
  • Make sure the device’s firmware is up-to-date
  • Wipe the sensor with a damp cloth and hand wash the belt well with soap and water as dirt can often cause connection errors.
  • Make sure the HRM is tight but comfortable around the chest to ensure a good connection; if the monitor moves or slips it may disrupt readings
  • Close the Runtastic app and remove the heart rate sensor from the strap. Wait 30 seconds, place the sensor back on the strap then reopen the app.
  • If this does not help, remove the battery and touch and hold both sensor points for at least 10 seconds. Wait 5 minutes then put the battery back in.

If your connection issues persist and the device’s LEDs are still working, it is possible that you’re experiencing a signal interference from a nearby app or device. In this case, please unpair your HRM from any previously paired apps or devices. Keep in mind that certain devices that transmit wireless signals could also be interfering with the connection, such as wireless headphones, wireless routers, or fitness machines, e.g. treadmills. You may need to move to a new environment away from any potential interferences.  

Note: You can also track your heart rate using wireless headphones with integrated HRM (Bluetooth Smart Technology). Use these same troubleshooting steps if you have any difficulties with the connection.
