How to Control a Sphero SPRK+ with a Raspberry Pi 3 and Node.js

I’m working on a demo that involves streaming Sphero data through the Azure IoT stack. I got my Sphero SPRK+ last week and quickly discovered that it only has Bluetooth Low Energy (BLE) enabled and not regular Bluetooth. So, I couldn’t get it to connect to my Windows or OSX machines because they don’t have a BLE chipset. I suspect that Sphero will push Bluetooth support via a firmware update later this fall. Until then, you can do the following to code against your SPRK+ using a Raspberry Pi 3, which ships with BLE.

Raspberry Pi 3

Get a Raspberry Pi 3 and plug it in. Monitor, keyboard, mouse, network cable.

Sphero SPRK+

Get a Sphero SPRK+ and plug it in.

Install Raspbian

Flash Raspbian Jessie onto a MicroSD card and boot up your RPI3. Use this blog post if you need help with this step.

Install TightVNC

This is helpful for accessing the RPI3 from your desktop. This step isn’t required if you want to control RPI3 using locally keyboard and mouse.

Install on Desktop: http://www.tightvnc.com/download.php

Install on RPI3: https://www.raspberrypi.org/documentation/remote-access/vnc/

Use the following to start VNC Server on your RPI3

vncserver :1

Use the following to get your RPI3 IP Address.

hostname -I

Then use that IP when connecting from your desktop

Pair the SPRK+

It will be named SK-XXXX.

You will need to click OK on your RPI3 here:

You might see this…ignore it.

Get SPRK+ BLE Address

Run this in Terminal

bluetoothctl

Copy the SPRK+ BLE Address. You will need it later.

Install Node.js on RPI3

Follow instructions in this blog post to get Node.js onto the RPI3

Install Sphero SDK

sudo npm install sphero
sudo npm install noble

You can ignore any errors you get with the noble install

Create Node.js File

cd ~
mkdir sphero
cd sphero
touch sphero.js
leafpad sphero.js

Copy Code to Node.js File

Change the BLE Address to your SPRK+ BLE Address

Open the sphero.js file and change the BLE Address to your SPRK+ BLE Address

Run and Watch with Delight!

sudo node sphero.js
