Using the MBED BLE library and Nordic Puck library this is a simple scoring application using Bluetooth LE. It monitors three analog inputs and triggers on reception of a pulse on any one recording data for a short period on all three. This is then published via BLE characteristics. It's a demonstrator for a new UI dev toolkit that is under development.
