How it happened

For the second time of the autumn season, the team @Microsoft Belux partnered with us to co-organize a Coding Battle. This time, the topic was IoT.

The Microsoft Belux team had already run several IoT events in the past. Lucky us, they had some interesting left overs to play with: 25 RapsberryPi3 with built in sensors. How cool is that ?!


Coding Battles take place in teams of 2. This means we could have a maximum capacity of 50 participants.

The tickets went like hot cakes and we rapidly had to setup waitlist. Apologies to those who eventually didn’t get a spot.
Even if in the beginning it felt a bit cramped, after rearranging the room, everyone manage to have enough space to let the hacking begin.

To help the participants get going with the challenges, Jan gave a thorough presentation on what can be done with Windows10 IoT Core. How you can setup an IoT Hub. How to send data to it…


Windows10 IoT Core is powerful and provides so many possibilities it’s not always easy to tame.

Time to count the points

After 2 hours and a half of intensive hacking, documentation reading and debugging, it was evaluation time. Most teams managed to at least get the first challenge that required them to run a “Hello World” app on their rapsberryPi3. That would get them 30 points.

A couple of teams managed to get over 100 pts by complete two or three challenges of the list.

The top 3 teams managed to pass the bar of 200 points. But the Coding Battle’s winners went a step further. Xavier & Nick almost completed all the challenges. Only the last challenge ‘Create a stream analytics job that is connected to the IoT HUB’ was missing. Impressive!

Experience sharing

Like for the first Coding Battle ‘Browser Wars’. Xavier has well-documented all the lessons learned of the evening.

Big thanks to him for sharing this with us. In case you want to try Windows10 IoT Core, this might prove very handy.
