Windows 10, IoT, Sphero 2 and Raspberry PI 2

Our last Windows 10 Theme Week post, we turn to Friend of the Blog, Mike Taulty and his two recent posts about Windows 10, Sphero 2 and Raspberry PI 2 (and Windows 8.1 Lib, WinPhone and PC)
It’s been a while since I played with my Sphero device and so I thought I’d see if I could get some code up and running on Windows 10 UWP to talk to it.
It turned out to be a little more of a ‘journey’ than I’d hoped for but, nonetheless it was fun
I last did any work with Sphero in this blog post where I wrote a Windows 8.1 application in HTML/JS on top of a C# library which itself wrapped a Sphero control library into a custom WinRT component such that it could be used from JS.
I thought I’d revisit something similar in Windows 10 but use C# and XAML for everything rather than bring in HTML/JS.
I went to look for a Sphero control library and ended up back here;
where I have to admit that it’s a bit sad to see that the WinRT library for talking to Sphero;
is still in a 0.9.0-preview variant built specifically for Windows 8.1 and it doesn’t look like anything much has changed with that library for around 2 years.
Bummer. I’d hope that perhaps this will change in the light
Putting the Basics Together on the PC
I paired my Sphero with my PC over bluetooth and I then took the RobotKit library that Sphero has on github and I build a quick Sphero control service out of it;
Moving to the Phone
Up until this point, all the bits that I’ve played with for Windows 10 Mobile I’ve done in an emulator but I didn’t think that was quite going to cut it here and so I went and dug out an old Lumia 920 which has a broken proximity sensor (making it very hard to end a phone call!) and I set about installing the Windows 10 Preview on it.
I’d say that it took around 1 day to get to the point where I had build 10512 installed onto this device. I had a number of problems including;
- Running out of storage space.
- Having updates repeatedly fail to install.
- Getting stuck in a loop where my phone would reboot, show cogs, fail with an unhappy face and then repeat.
In the end, I had to resort to the Windows Phone Recovery Tool in order to re-flash the phone, start the update process over again (without restoring any backup to the phone) and get it updated to Windows 10.
Actually driving the ball;
Moving to Windows IoT Core
In terms of moving this to Windows IoT Core, I hit a really interesting scenario which I thought I’d share. Firstly, I powered up my Raspberry PI 2 and went to its web admin UI in order to pair the device with the Sphero;
This has been a long post – what has it covered so far?
- Taking a Windows 8.1 library and using it in a Windows 10 project.
- Making that Windows 10 project work across PC, Phone and Raspberry PI 2.
- Dealing with a few hiccups along the way!
I’ll follow up the post with another where I’ll see if I can control the Sphero from the PI without having to use the UI and a mouse – I’ll add some buttons onto a breadboard and see how that works out.
In the meantime, all the code for this post is here for download if you want to do something with it.

Following on from that previous post, I wanted to see if I could gain some control over my Sphero device without having to plug a mouse into the Raspberry PI and control the UI.
I had a search through my Sunfounder kit of components and came up with this interesting looking gadget which is a Rotary Encoder with a switch built into it;
It serves 2 purposes – the pole in the middle can be rotated and the device can report the direction of that rotation. That pole can also be depressed to act as a switch.
I figured that this would give me enough to at least rotate the Raspberry PI and provide some kind of speed control and so I went with it.
