Does the HR strap transmit in Bluetooth 4.0 or LE?
I want the strap to be able to communicate with my iphone 6 as well as the wrist piece. Does the strap use Bluetooth 4.0 or Bluetooth LE?
That strap only connects with the watch it comes with. It does not have Bluetooth so it would not sync with your smartphone unless you buy one that states that it's Bluetooth, such as the Bluetooth H7 Polar Smart Heart Rate Sensor.
