Troubleshoot Your Bluetooth Low Energy Heart Rate Monitor (BLE HRM)

Fitdigits is compatible with Bluetooth Compatible sensors as long as your device is compatible. If you are having issues pairing or are getting inaccurate readings, try the following troubleshooting steps:

      • Is Your Device Compatible: View our Compatible Devices for more details.
      • Have you upgraded your app: You must have upgraded your app in order to use heart rate training and tracking features.
      • Wet the Electrodes: Make sure the contact strips (electrodes) on either side of the heartbeat pod / transmitter are wet with water, saliva, or gel to increase connectivity.
      • Clean your HRM: It is recommended to clean your HRM strap after every use. Rinse the strap under running water after every use and hang to dry. Clean the strap gently with a mild soap and water solution when needed. Do not use moisturizing soaps, because they can leave residue on the strap. Failure to do so will resort in inaccurate readings.
      • Reset Bluetooth: Try going to your Settings->Bluetooth, turn Bluetooth OFF, wait for about 30 seconds, and turn it back on.
      • Trash and Re-Pair SensorIf the app cannot acquire your sensor when beginning a workout, Trash and Re-Pair the Sensor
      • Manually Close Your App: Exit the app and then double tap the iPhone home button. Look for the Fitdigits app and swipe up. Your app has now been manually closed. Relaunch the app and try pairing again.
      • Discharge Your SensorIf you cannot pair the sensor, try discharging the sensor
      • Change Batteries: Make sure your belt’s battery level is not low. If in doubt, try changing the battery to see if it fixes the problem.
      • Is Your HRM Paired With Another Device : Make sure no other Device is currently connected and communicating with your BLE heart rate monitor. If your heart rate monitor is paired with another device, you may not be able to use the HRM
      • Close All Other Apps Paired With Your HRM: If there are any other apps on your device that is communicating with your BLE heart rate monitor, terminate them. The HRM may only be able to pair with one fitness app at a time.
      • Power Down Your Device: If none of the above steps resolve your issue, power down your device and then turn it back on.

If you still cannot pair with your Bluetooth 4.0 (BLE) HRM, contact Fitdigits Customer Support.

    Regarding the “Is Your HRM Paired With Another iPhone,” I have found you can pair a Wahoo HR Blue with more than one phone and the Blue HR works seamlessly with both. Keep in mind, I’m talking about using one iPhone 4S at a time.

    For example, my wife and I shared one for a few days while we made sure it was something we wanted to buy two of and it worked interchangeably with both of our phones.

    EXTRA NOTE (pairing a second Blue HR to same phone)
    After buying a second Blue HR, I found that I had to press and hold the “Bluetooth 4.0” text that was a bright blue color (like “Location” is in the screenshot above) in order to bring up some type of bluetooth ID window in Digifit. I think I was able to trashcan/delete my 1st Blue HR which enabled me to pair the new Blue HR. (On my wife’s phone, remove my Blue so I could pair her new one.) I had a heck of a time pairing the new Blue HR until I did this step. Odd stuff. I was able to get the Wahoo app to pair within seconds. (To be fair, I had freshly installed it to see if it could pair after having issues with the new Blue HR in digifit.) Probably a fairly rare issue… but it wasn’t apparent to me that I could click on the text and it might help someone. It took a fair amount of fiddling (turn sensor off/on, turn phone BT off/on, reboot phone, click around like crazy, try airplane mode off/on… then happened upon clicking the blue text.)

  2. Hi all,

    We also found this on the Polar forum and have suggested it as an additional troubleshooting step:

    Delete the app and discharge the sensor:

    1. Make note of your Digifit username and password. You can find your username under Settings -> My Profile, under Email.
    2. Perform a cloud sync.
    3. Hold app icon until “x” shows in left corner. Tap x to delete. (NOTE: if you have an Apple iOS below 5.0 for your device, this option will not work for you as you will not be able to re-download the app).
    4. Go to app store and download the Digifit free app.
    5. Choose existing user, enter user name and password, tap login and perform sync.

    Once you reinstall, please remove the peanut from the strap of your Polar H7/Wahoo Blue and remove the battery. Then, mount the peanut (without the battery inserted) onto the strap and try to pair with the app (this won't work, of course, because there is no battery). As soon as the app responds with "No sensors detected," go ahead and remove the peanut and reinsert the battery, reset your bluetooth (turn off and then turn back on), hard-close the app and then reopen it. Then try to pair.

    I struggled for two days trying to establish why my HR7 had ceased connecting to,the iphone. I even bought. A new battery, still no working. T

  4. My H7 connected without a glitch when it first came out the box. I used it 3 times before it lost sync with my iphone5.
    I tried all suggestions made above, none of which worked. I finally got my H7 working yesterday… The remedial action was quite simple. I removed the battery, connected the sensor to the strap and then wore the strap for ~5 mins. This was enough to completely discharge the sensor.
    Upon reinserting the battery, the sensor synced with my phone instantly.

    Seems the H7 has a pretty annoying bug… It would certainly benefit from a hard reset button!

  5. Tony Gibson says:

    I have the Wahoo Blue HR, with the same symptoms – unable to pair, even after replacing the battery. I then used the advice of 'discharging' by wearing the device without a battery installed, and then putting the battery back in. Then paired right away without issues.

  6. Paul Willis says:

    Tried this trick of wearing the monitor without a batery and it worked for me, now pairs fine.

  7. Jim Greene says:

    I tried to pair for 3 days using many suggestions on the internet, this one worked!

    I've tried all of these with a new battery and none have worked for me 🙁 Even lost all of my previous training history on polar beat – not very happy now 🙁

  10. Graeme Clark says:

    taking battery out and wearing without battery did the trick, just a pity I had to lose all my history in the process

  11. Dirk Buikema says:

    This worked for me. Had to go through all these steps

  12. Tom Vale says:

    has anyone had luck using the instructions below after updating to iOS 7.1.1? I upgraded and now it won't or can't find the sensor.
    I can't believe how bad the support is from Polar and Digifit.

    Same for me; i wasted significantly more time again and it still doesn't link the sensor.
    My iPhone bluetooth can't find the HRM

  14. Traci Adams says:

    H7 stopped working yesterday in the middle of a bike ride. Read your responses ~ taking the battery out, wearing the HR without a battery in for 5 mins and reinstalling the battery did the trick! Thanks!!!

  15. Linda A. Bishop says:

    I have a Garmin HRM chest strap (brand new) and iPhone 4S. I am unable to get the phone to recognize the Garmin. In My Settings, My Sensors – I get a pop-up reads" No response from ANT+ accessory. Would taking battery out and reinserting help maybe?

  16. I have this app for 8 months now on my iPhone 5 with a H7. It worked perfectly until 4 weeks ago. Following your suggestions – including this somewhat funny 'unmounting'/discharging I was able to re-pair. But three days ago the same happened and I tried everything of the above, all routines. Nothing works. Are there more people with the same problem?

  17. Mark Davison says:

    My H7 failed to connect via bluetooth on its second outing, however it did connect to my cycle computer using the normal gym mode. I tried everything but it would not connect. I then saw some posts on this site. The answer is put the strap on make sure the sensors are damp, as usual. Remove the H7 unit by and unclipping it. Remove the battery. Re clip the H7 unit to the strap whilst you are still wearing it. Leave the unit on for about 30 seconds. Remove the H7 unit and insert battery, close unit and reconnect H7 unit to the strap. You should now find the bluetooth is functioning correctly. Normally removing the battery from a unit is the equivalent to giving it a hard reset however on this unit it appears that you need to do this extra drill to get the unit to completely reset. Hope this is helpful and works for you as it did for me.

  18. I have found that I need to go to "my sensors", delete the paired device and re – pair my H7.

  23. Had same problem. Found the issue was a conflict witht he Apple Health app. If the Update Health Date was on then the strap wouldn't connect to Polar Beat. Shut it off and everything is back working.

  24. I have 3 H7 polar units now. they all have a 6 digit ID code. i notice the newer ones are 8 digits long.
    now the 6 digit coded H& units are no longer working for no reason. i have clients who are noticing this too. i use the polar team and polar club apps for our facilitys. anyone else having this issue?
