Garmin Forerunner 235 / 645 / 935 (older)
Not compatible on its ownWhy
This device can measure your heart rate for itself, but it can't share that live heart-rate data over Bluetooth with SENOS. This is a limit set by the manufacturer — it isn't something SENOS can change.
What to do
Pair a small Bluetooth heart-rate sensor (chest or arm strap, from around £25) directly with SENOS. You can keep wearing your device exactly as you do now.
Show me how
- Put on your heart-rate sensor.
- In SENOS, choose 'Connect heart rate' and select the sensor.
- Your watch or band carries on recording as normal.
Polar H10 chest strap (about £77, best), Coospo H808S (about £30, budget) or COROS arm band (about £69, most comfortable).
