Bluetooth LE/Ant+ devices

First, ensure that the bluetooth device is known and paired with your smartphone or tablet. In order to get Coxswain to work with the Bluetooth device, the option "Bluetooth LE/Ant+" must be set within the settings.

1. Go to Settings
2. Scroll to the section "Hardware"
3. Click on "Sensors" which will open a select window
4. Choose "Bluetooth"
5. Ensure Bluetooth and Position is enabled (Position is needed as bluetooth won't work without it see here for more details Bluetooth spec for Android )

Now if you connect your Waterrower and open Coxswain, a window should appear which will allow you to select your bluetooth heart rate monitor. On the bottom of this window you will have two additional options

• only bluetooth heart device ==> this option only shows bluetooth devices which are heart rate monitors
• remember selection ==> if set you current heart rate monitor is used all the time if detected. No need to choose it again.
