Heartbeat Authentication

Base files added. Currently some of the hearbeat data seems to increase continuously as per the plots. Better samples needed

pip install matplotlib

Increased Precision of Accelerometer

Too increase the precision from the accelerometer please replace the original contiki driver with the modified driver mpu-9250-sensor.c. It returns the raw sensor value. It can be converted to G with the following formula:

(raw_data * 1.0) / (32768 / 2);

You find the file in contiki-git/platform/srf06-cc26xx/sensortag

To use that file please make sure to run make clean before building the source code. (FYI: The sensor is per default in 2G range configured that has the highest possible precision.)
