The sensor can be connected to compatible devices via Bluetooth Low Energy (BLE), which basically also includes the Apple Watch. Pairing takes place via Bluetooth, and the sensor supports the connection with fitness apps and devices that use BLE. A connection with the Apple Watch is therefore possible as it supports BLE.
Experience reports and tests also confirm that pairing the sensor with the Apple Watch is simple and functional, enabling reliable heart rate measurement.
It is important to switch on the sensor in heart rate mode and pair the Apple Watch via Bluetooth in order to receive the heart rate values in real time.
