How to Connect Your Garmin to FivePointFive

Summary

To connect your Garmin watch to FivePointFive, you must do three things:

Turn on Broadcast HR on your watch (ensuring you can see your heart rate appear)
Make sure Bluetooth is enabled for FivePointFive on your phone
Connect to class heart rate in the FivePointFive app

Step 1 — Start Heart Rate Broadcast on Your Garmin

Find your model family below and follow the instructions:

Fenix / epix / Enduro / Descent / MARQ / quatix / tactix

From the Heart Rate widget, press and hold MENU
Open Heart Rate Options
Select Broadcast Heart Rate
Press START to begin broadcasting

Forerunner

Tap UP/MENU and scroll until you find the Heart Rate graph
Tap Start/Stop — the watch will start measuring your HR
Tap Start/Stop and choose Broadcast HR
Tap Start/Stop for a third time to actually start broadcasting HR

Instinct (incl. Solar / Crossover)

From the Heart Rate widget, press and hold MENU
Open Heart Rate Options
Select Broadcast Heart Rate
Press START to begin broadcasting

Venu / vívoactive / vívosmart

Open Settings on your watch
Navigate to Watch Sensors
Choose Wrist Heart Rate
Select Broadcast Heart Rate
Press Start to begin broadcasting

Alternative method (works on many Garmin models)

Press and hold LIGHT/CTRL to open Controls
Select Broadcast Heart Rate

If the option is missing from Controls:

Press and hold MENU
Open Controls
Tap Add
Select Broadcast Heart Rate

Step 2 — Check Bluetooth Permissions on Your Phone

Open Settings on your phone
Open Privacy & Security
Open Bluetooth
Find FivePointFive
Ensure the toggle is ON

Step 3 — Connect to Class Heart Rate in the FivePointFive App

Open the FivePointFive app
Select your class card
Tap the class heart rate button
Tap Record HR with other wearable
Under Bluetooth Devices, tap your Garmin model
When the heart rate circle button appears with digits on it (this may take a few seconds), tap Join class

Step 4 — Stop Broadcast & End Class

On your Garmin: press any button → choose Stop Broadcast
In FivePointFive: end your class after you receive AI Coach feedback and HR performance results

Important Tips

Garmin uses Bluetooth only — ANT+ is not supported by FivePointFive.
You must enable Broadcast HR on the watch every time you join a class.
If you don’t see your device, take a screenshot of the Bluetooth wearable list in the app and share it with us via Instabug, or contact support@fivepointfive.com.

Troubleshooting

1. The watch isn’t in Broadcast Mode

By default, the watch only uses Bluetooth to talk to the Garmin Connect app. To let FivePointFive see it, you must manually start a broadcast.

How to fix: On the watch, hold UP → Health & Wellness → Wrist Heart Rate → Broadcast Heart Rate → Press Start.

Result: The watch will now appear in your app’s Bluetooth device list as a heart rate monitor.

2. The Bluetooth channel is busy

Some Garmin models (e.g. Forerunner 255) can only maintain one Bluetooth sensor connection at a time.

The problem: If the watch is already connected to another app (like Zwift or Peloton) on a different device via Bluetooth, it will be invisible to FivePointFive.

How to fix: Ensure no other training apps are open and actively paired to the watch’s Bluetooth signal.

3. Permission and pairing conflicts

If the watch is paired directly in the phone’s system Bluetooth settings, FivePointFive might not be able to access the data stream.

How to fix:

Permissions: Ensure FivePointFive has “Nearby Devices” or “Bluetooth” permissions enabled in your phone’s settings.
Don’t pair via Phone menu: Do not pair the watch in the phone’s main Bluetooth menu. Only pair it within the FivePointFive app or Garmin Connect.
Battery Saver: Ensure Battery Saver mode is off on the watch, as it can disable Bluetooth to save power.
