Heart Rate Integration

Where can I purchase a Polar Wearlink+ Bluetooth heart rate device?

You can purchase the Polar Wearlink+ Bluetooth transmitter $79.95 from Amazon.com here.

Will the Zephyr HxM work with CardioTrainer?

Not currently. All of our attention has been focused on getting the integration for the Polar device to work, so there aren't any plans right now for Zephyr. In the future, we hope to expand our support of other devices.  

How do I pair my Android device with my Polar Wearlink+ Bluetooth transmitter?

On most phones, the following setup will work:
  1. Wet the contacts of your heart rate belt and put it on.
  2. Open CardioTrainer and select the green "Start Workout" button.
  3. Click "Heart Rate Setup" on the left side of the screen.
  4. If you don't have Bluetooth turned on, you'll see a dialog asking to you to turn it on. Select "Yes."
  5. CardioTrainer will automatically search for your Polar device.
  6. When it finds it, enter the pairing code "0000."
  7. You'll be taken back to the tracking 

What do I do if CardioTrainer can't connect to my Polar heart rate device?

In testing, we've found that many Android devices pair with Bluetooth devices differently. If you're not able to connect to your heart rate monitor through the CardioTrainer app, follow these instructions:
  1. First, you'll need to be wearing your heart rate strap (and the contacts should be moistened).
  2. Go to your phone's home screen, hit the Menu button.
  3. Select Settings > Wireless & networks > Bluetooth settings.
  4. Check the box to turn on Bluetooth, and then click "Scan for devices."
  5. Wait for your device to search for available Bluetooth devices, and the select "Polar iWL"
  6. The code for pairing to your heart rate strap is "0000."
Once you've paired to your heart rate device:
  1. Go back into CardioTrainer
  2. Hit the "Start Workout" button
  3. Click "Heart Rate Setup."
  4. Click "I already have one."
  5. After a few seconds, your heart rate will appear on the side.
If you're still having trouble, make sure you check that your heart rate device has fresh batteries.

Why does my heart rate recording look so erratic?

Erratic readings are usually caused by poor conductivity, dirty electrodes or electrical interference.  It is possible that the treadmill is too electrically noisy and causing interference to the wireless signal. 

Please make sure the electrodes on the strap are wet with water before wearing it. The electrodes are the grey mesh areas. 

The strap should be washed in soap and warm water after each use and every other week in the washing machine to remove the salt left behind by perspiration. Try washing the strap (using a washing pouch) in the washing machine. The vigorous movement of the machine helps get the electrodes clean.

Also, make sure that you completely disconnect the transmitter from the strap after each use otherwise corrosion can build up on the snaps if you leave the transmitter snapped together and this will cause erratic or zero readings. Also leaving it connected will drain the battery prematurely.

If you're having consistent problems, please visit our bug tracker. Search for the issue you're experiencing, and star the issue that's most akin to yours. If you don't see any pertinent issues, create your own bug report. Please be concise and include as much information as possible to help us reproduce the issue (remember to include your phone's make/model and the versions of Android and CardioTrainer).

What do I do if the Heart Rate drops out?

See answers to the questions above. Then try restarting your phone, detaching the bluetooth transmitter unit from the belt, and reconnecting everything.

Can I use a Bluetooth headset while I'm exercising with my Bluetooth heart rate device?

We've done tests and have bee able to make phone calls with Bluetooth headsets while using the Wearlink+ device. There weren't any connection problems, but if you do have trouble using both, there is a very good chance that this is a hardware limitation, related to something like bandwidth. We would to hear anymore details you have, and please feel free to share on the CardioTrainer User Group.
