ChromeBluetooth
Demo to show how to use Chrome to connect to a heart rate monitor, as well as a Bluetooth smart bulb. The ultimate goal creates a "Stress Display" that uses the heart rate value, to display a "traffic light" stress meter. This consists of various shades of green, yellow or red depending on the heart rate value.
This will demonstrate how to use Chromes' bluetooth capabilities to:
- Read battery status
- Read heart rate information
- Hacking into a smart bulb (Sharper Image LED Bulb Bluetooth Speaker - SBT5007)
Runs on Chrome browsers on:
- Mac
- PC
- Smartphones
- Android
- IPhone (Not working currently)
- Windows (Not tested)
Requirements:
- Chrome version 56+
To try it out! (Live Demo):
If you do not have a Bluetooth Heart-Rate monitor:
- You can use on android: "BLE Peripheral Simulator"
