Firmware for wearable ECG and Android app

Project Description

We have developed a firmware for provided ECG (electrocardiogram) device based on nRF51 along with the Android application. This software complex allows transferring data (ECG, accelerometer, sound and temperature) from wearable ECG device to an Android smartphone via Bluetooth 4.0 in a real time. An internal flash memory was used as a temporary buffer for a situation when an ECG device loses connection with a smartphone.
