WHOOP – Broadcast your Heart Rate over ANT+

Can’t use WHOOP‘s heart rate on your old bike computer? Read on…

In your WHOOP app, you probably already know how to enable the WHOOP band to broadcast your heart rate over Bluetooth (BLE). That’s normally enough to handle most people’s needs. However, some of you might have an old Garmin bike computer, an old Garmin Forerunner or an old piece of gym equipment that only links to fitness sensors using ANT+. Here’s what you need to do to convert WHOOP’s Bluetooth signal to ANT+.

NPE WYUR

You’ll need to buy WYUR which is a converter made by a company called North Pole Engineering (NPE). It’s a moderately priced item and looks like a footpod or bike speed/cadence sensor. As well as re-broadcasting WHOOP HR over ANT+ it can also act as a bike pod for accurate speed/cadence plus do lots of clever things with Apple TVs, Zwift and RUNN, the most advanced smart treadmill sensor.

One-Time setup

First up, double-check check you have enabled HR Broadcast in the Whoop app. [ More> Device Settings> Broadcast Heart Rate=On ].

Use NPE’s Configurez app to find WYUR and then search for Whoop. Once found, you’ll need to double-check the app’s settings to ensure that ANT+ re-broadcast is on. Don’t forget to save Whoop’s info into the WYUR’s settings and you are done.

You don’t need the Configurez app anymore.

Pairing

to prove to myself that this all worked, I paired the WYUR to an old Garmin Edge 820 which only accepts ANT+ sensors. Note that by pairing the Edge 820 to WYUR you are using WHOOP’s HR data as the WYUR converts it to ANT+ during a workout.

In Use

You will need to take the WYUR sensor with you when you exercise.

As an added bonus, WYUR can also act as a speed or cadence sensor when riding and attached to either your wheel or pedal (crank)

 

when Not In Use

If you use WYUR with an indoor bike trainer that is left switched on the WYUR will also stay switched on. Similarly, if you have Whoop continually broadcasting its HR then WYUR will stay on. To save WYUR’s battery you will need to turn it off or turn off one of the sources so that it can go to sleep.

 

WYUR More

WYUR comes with various brackets/clasps. You can fasten these to your shoes or bike. You could probably also fasten it over the WHOOP strap itself but that doesn’t look great 😉

WYUR also broadcasts WHOOP’s HR over the old Polar 5KHz format called Gymlink

Alternatives

NPE make another product called STIC. This has pretty much the exact same re-broadcasting functionality as WYUR except it is designed solely for indoor use and takes its power from a USB socket. It has no battery.

Take Out

NPE creates smart and unique items that fix uncommon issues related to integrating older technologies with newer ones. WYUR and STIC are likely the best solutions for this type of problem until the demand for them decreases as ever more products support both ANT+ and BLE. However, even now, some products lack sufficient simultaneous BLE channels, and NPE has solutions for that too.

The main drawback of WYUR is that you need to carry it, and you must be mindful of its battery life by making sure to turn off sensors when not in use.

WUYR is available now directly from NPE for £75, $90, STIC/CORD RRPs at £41, $50,

  1. It’s kind of fascinating that a device to rebroadcast ANT+ as BTLE exists and there is a market to sustain it. This particular use case doesn’t make a ton of sense to me though.

    The WYUR gizmo costs the same as just buying a Polar H10 chest strap kit. The Polar H10 just directly provides ANT+ support as well as a more accurate HRM than any optical sensor without introducing the complexity or latency of rebroadcasting.

    The H10 also supports Gymlink.

    1. some people wont want to wear more sensors
      guy uses whoop 95% of the time for gym/run and occasionally rides for fun for the other 5%, he has an old Garmin.

      not a huge market but these people exist.

  2. What’s even more fascinating is that the sales and pricing of this small niche product seem to be able to pay for ANT+ licensing fees. Something major sports watch companies can’t seem to afford.

    1. quite!
      i think the licnce fee is very low and perhaps only one of the reason why the companies you are thinking of dont support ant+, as support will also require additional software fetures to be developed and maintained
