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+

If you do not have a Bluetooth Heart-Rate monitor:

• You can use on android: "BLE Peripheral Simulator"
