This utility app allows owners of GemTot bluetooth beacons to easily configure, test and demonstrate them. Distance demonstration: Demonstrates how an app is aware of a beacon's relative proximity when moving closer or further away from a beacon source and how the RSSI and power calibration of the beacon can be used to calculate a crude distance to the beacon source. Proximity demonstration: Demonstrates how the device's proximity to the beacon can trigger 3 different states (immediate, near and far), also shows how an app can respond to the event of no longer being able to see a beacon. Lock screen demonstration: Demonstrates how entering or exiting a beacon region can trigger a local notification and how a notification could be used to deliver content to Apple Wallet. This demo requires that background location monitoring and local notifications are enabled. Please note that continued use of GPS running in the background can dramatically decrease battery life. This app acts as a tool to demonstrate the capabilities of iBeacon. To save battery life, location permissions should be disabled when the app is not in use.
