App note: Bluetooth low energy digital pedometer demo design

An application note (PDF!) from Microchip: A Bluetooth low energy digital pedometer demo design

A digital pedometer is a portable electronic device that counts each step a person takes by detecting the motion of the person’s body with an accelerometer.
This application note demonstrates the implementation of a Bluetooth Low Energy Digital Pedometer using the Microchip PIC16LF1718, a cost effective 8-bit microcontroller with extreme low power (XLP), the Microchip RN4020 Bluetooth 4.1 Low Energy Module, and the Bosch Sensortec BMA250E digital triaxial accelerometer.
The Microchip Pedometer Demo can be worn on the wrist like a bracelet/watch. The on-board RN4020 BLE module allows the pedometer demo to communicate with a smartphone or tablet on which the user’s exercise progress can be tracked. The pedometer demo is powered by a single 3V coin lithium battery (CR2032).
