Bluetooth GPS For Avare is a free AddOn for our free Avare app. This app can serve as the location sensor for one or more other devices running Avare. This enables pilots to place a secondary Android device with a built-in GPS receiver in the optimal location for satellite reception (for example, beneath the windshield with an unobstructed view of the sky). That device's GPS data is then sent via Bluetooth by this app, to one or more other Android devices running Avare (such as a tablet or phone attached to the aircraft control yoke, panel, or pilot's kneeboard).
