iPad/Apple Watch/iphone/heartcast connection not working

I’m running heartcast on my Apple Watch and iPhone. Running TR on my iPad.

I had it working for one workout last week.

I can’t get it to work again. My iPhone is showing up on my TR devices screen, but when I hit pair, it says “pairing” for a minute and then it doesn’t connect. The iPhone stays on the devices screen.

Hey there and welcome to the TR community!

Sorry to hear about the connectivity trouble – there are a few things we can try to fix this, though.

First, if it’s been a while, we’d recommend restarting all of your devices involved in this process – so, in this case, your Apple Watch, iPhone, and iPad.

Once that’s done, make sure that your Bluetooth devices aren’t connecting to something like another laptop/tablet that may be on, but that you’re not using for your workouts. Bluetooth can only connect to one device at a time, so if it’s connecting to another electronic device that you have turned on nearby, your Apple Watch/iPhone won’t be able to connect to TR on your iPad.

Similarly, we’d recommend checking the Settings > Bluetooth page on your iPad itself. Your Apple Watch/iPhone may be connecting to your iPad directly before it can get the chance to connect to the TR app running on your iPad. If that’s the case, disconnect your Apple Watch/iPhone from your iPad’s Bluetooth Settings page, then try connecting to the TR app.

Those should be some good first steps to try out – give them a shot and let me know how it goes! Feel free to ask any additional questions you may have.

Thanks so much for the reply.

I tried all of those things, but it didn’t work. Frustrating since I got it to work one time.

I turned all 3 devices off and on.

On my watch, nothing shows up as connected.
On my phone, the watch is the only thing connected.
On my ipad, nothing shows up as connected.

In TR devices,
my Wahoo KICKR shows up as paired.
My phone shows up as a box with “Pair Device”. When I click “Pair Device”, it switches to “Pairing Device” for a few seconds and then it flips back to “Pair Device”.
My husband’s Polar HR monitor is showing up as available as well. It also says “Pair Device”.

Any other ideas?

Sorry to hear those steps didn’t solve the issue – I’m going to check in with the rest of our Support Team here to get some additional suggestions.

Hey @JaneSherman :slight_smile: Circling back for Zack.

I found this forum thread where the workaround listed below worked for an athlete:

When using 3rd party-apps, you’ll likely need to use TrainerRoad on another device (such as your iPad), if you have HeartCast on your phone.

The app used wasn’t HeartCast, however, athletes have had success sending heart rate data from their apple watch to TrainerRoad using the third-party app called BlueHeart. Once you have the BlueHeart app, here’s how you can broadcast your HR from your Apple Watch into TrainerRoad:

  • Open BlueHeart on your Apple Watch.
  • Pick the ‘Spin’ activity type.
  • In the Devices tab of TrainerRoad, select ‘BlueHeart’ or ‘’ to connect it.
  • Keep in mind that you won’t be able to connect BlueHeart (or HeartCast, I assume) to TrainerRoad if you’re running TrainerRoad on your phone.

Let me know if you have any questions about this!
