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

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