Setting up your Thunderboard Sense Kit

Requirements

  • Thunderboard Sense 2
  • Coin cell battery or Micro-USB cable (not included)
  • Android or iOS mobile phone

Unleash the power of Thunderboard Sense. Let's start with unboxing, downloading the app, and exploring the sensors and basic features.

Note: Refer to the BLE Demo User's Guide for more detailed information on the Thunderboard Sense BLE demo

Step 1: Unbox Thunderboard Sense

  1. Purchase a Thunderboard Sense 2 if you don't already have one.
  2. Remove Thunderboard Sense from the box.
  3. Supply power to your Thunderboard Sense: place a battery in the coin cell battery holder on the bottom of the board, or plugin a micro-USB cable.

Note: The air quality sensor and RGB LEDs require external power. You will need to power the board via USB to test these.

Step 2: Use the Thunderboard Mobile App

  1. Download the Thunderboard mobile app
  2. Enable Bluetooth on your mobile phone

Launch the app to discover your Thunderboard Sense.

Press the Reset button on the Thunderboard Sense to restart advertising.    

After connecting with the Thunderboard Sense you will be taken to the app dashboard.    

Step 3: Try the Sensors

When you have successfully connected the Thunderboard Sense we are ready to test the board features.

  • Select the motion and calibrate the board and test the accelerometer and gyroscope.
  • Select "Environment" to test a number of environmental sensors
    • Humidity and Temperature: Blow or cover the temp. sensor with your finger
    • Light: Cover or shine a light on the board
    • UV: Measure UV index from the sun or a UV light
    • Sound: Talk, whistle, sing or clap to record audio levels
    • Pressure: Move the board from floor to ceiling to test the barometric pressure sensor
    • Magnetic Field and Door State: Move a magnet near the Hall Effect sensor and observe the effects
  • Select "I/O" to test a buttons and LEDs.
    • Switches: Press the two push buttons on the board    
    • LEDs: The app switches will turn on/off the small LEDs on the board
    • RGB LEDs: Control the color and brightness of the RGB LEDs  


Developing with your Thunderboard Sense Kit

Requirements

  • Thunderboard Sense
  • Micro-USB cable
  • Simplicity Studio
  • Bluetooth SDK

Step 1: Get Simplicity Studio

Download Simplicity Studio and run the installer. If you already have Simplicity Studio installed, you can skip to Step 5.

Step 2: Connect to your computer

Connect the Thunderboard Sense to your computer using a micro-USB B cable. A blue LED should turn on next to the USB connector to verify connectivity.

Step 3: Install drivers

Follow the Installation Wizard so it can install the basic drivers.

Step 4: Log-in

By logging in, you will get access to the required wireless stacks and SDKs for Thunderboard Sense. You do not need to register your Thunderboard Sense at this time.

Step 5: Install the latest software

5a. If this is your first time to install Simplicity Studio, simply follow the Install Wizard recommendations based on the detected “Connected Devices”.

5b. If you already had Simplicity Studio installed, click on the “Update Software” button and choose the “Install Wizard” from the bottom of the dialog box.

5c. Insure that latest version of the "Bluetooth SDK" (version 2.6 or later) is installed.

5d. In the Launcher window, click to change the preferred SDK, and choose the Gecko SDK Suite featuring the latest Bluetooth SDK.

Step 6: Cloning a Project

In the Launcher perspective, with your Sense kit selected in the Devices window, select the desired project from the available “Software Examples”. This action will clone the pre-tested project. From here you can explore and modify and source code, compile, and debug.
