Do I need to turn on Bluetooth to connect Cor all the time?
No, you don’t need to turn on Bluetooth on your phone all the time.
Turn on Bluetooth when you need to sync data, receive phone call alerts or app notifications, update firmware, and set alarms.
Turn off Bluetooth, Cor will still track your steps, sleep, heart rate and vibrate for alarms.
You can turn on Bluetooth to sync your device to the mobile phone when you need to view the data through Amazfit App.
