Pair MyHRM with a Garmin Edge

Field-validated on the Edge 840 and Edge 1050. Garmin discovery works when the iPhone is treated only as a Bluetooth heart-rate sensor during pairing — not as a phone — and when no other heart-rate sensor is connected to the Edge.

1. 1

   Disable the phone under Settings → Connected Features

   On the Edge, open Settings → Connected Features → Phone and turn it off (or choose Forget Phone). Testers found this step was required every time on the Edge 840 and 1050 — otherwise the Edge reconnects to the iPhone as a phone instead of as the sensor.

2. 2

   Remove any heart-rate strap already paired on the Edge

   Open Sensors, select the existing heart-rate monitor, and choose Remove — or simply power the strap off. The Edge will not add “MyHRM” while another heart-rate sensor is connected.

3. 3

   Fully quit Garmin Connect on the iPhone

   Swipe Garmin Connect away in the app switcher so it is not holding the Bluetooth link.

4. 4

   Open MyHRM and keep it foregrounded

   Launch MyHRM on the iPhone and leave it on screen.

5. 5

   Tap Start Broadcasting

   MyHRM begins advertising as a Bluetooth heart-rate sensor named “MyHRM”.

6. 6

   On the Edge: Sensors → Add Sensor → Heart Rate

   Let the Edge scan for heart-rate sensors.

7. 7

   Select “MyHRM”

   The Edge pairs it like any Bluetooth chest strap. Your Watch can stay paired to the iPhone.

If MyHRM was paired but won’t reconnect

MyHRM already retries in the background on its own — fast for the first 30 seconds after a drop, then every 30 seconds after that — and refreshes again whenever you bring the app to the foreground. If Garmin stays disconnected for 90 seconds, the app shows an on-screen warning; that is your cue to work through the checklist below.

1. 1

   Confirm the phone is still disabled in Connected Features

   Settings → Connected Features → Phone should be off. A live phone connection owns the iPhone Bluetooth link and blocks the sensor record.

2. 2

   Confirm no other heart-rate sensor is connected

   If a strap has reconnected to the Edge, remove or power it off before retrying.

3. 3

   Confirm Garmin Connect is fully quit on the iPhone

   Close it from the app switcher.

4. 4

   Open MyHRM and keep it foregrounded

   Bring the app to the front before retrying.

5. 5

   Tap Refresh Sensor

   This rebuilds the MyHRM Bluetooth advertisement and GATT service — the recommended response to the 90-second disconnect warning.

6. 6

   Reconnect “MyHRM” from the Garmin sensor list

   Re-select it under Sensors → Heart Rate.

Good to know

• An iPhone cannot expose a second, independent Bluetooth identity. If a head unit also has that iPhone saved as a phone, it may reconnect to the phone record instead of the “MyHRM” sensor record — hence disabling the phone under Connected Features.
• A Garmin Edge pairs one heart-rate sensor at a time. Any strap or monitor already connected takes priority, so remove or power it off before adding “MyHRM”.
• Refresh Sensor rebuilds the advertisement and service, but it cannot override a head-unit phone connection that already owns the iPhone Bluetooth link.
• Bluetooth heart-rate sensors normally connect to one head unit at a time. Disconnect “MyHRM” from Garmin, a scanner app, or another device before pairing it somewhere else.
• MyHRM does not broadcast ANT+. Devices that only accept ANT+ heart-rate sensors will not see it.
• Still stuck? MyHRM keeps a protected local diagnostic log of connection attempts on your iPhone. Send us the details through the Feedback page and, if useful, the relevant log entries from Files → On My iPhone → My Heart Rate Strap.
