What?

This repo provides the bases to explore room-level positioning (using RSSI) and motion sensing for activity analysis.

It uses an accelerometer, gyroscope (BMI160) and a BLE powered microcontroller (nRF51), all squeezed on a coin cell battery sized board:

The software provided is a simple Web BLE test using serial-like communication.

How?

Firmware and Hardware

1. Get the hardware here (if the link dies this archive should help to find a similare device).

2. Documentation/tuto: see the firmware and hardware folders.

Software (web app)

It was tested on Chrome/Chromium for now, and works on almost any OS (android too).

• Win/Linux, you might have to go to chrome://flags/#enable-experimental-web-platform-features, enable the highlighted flag, and restart Chrome for now.

• Ubuntu 16.04 users must update Bluez, this tutorial should help.

• Other platforms: see the Implementation Status.

If everything works, you should be able to see a second counter once connected to your BLE device with this interface:
