1. Building IoT devices
for fun and profit
Jan Jongboom Developer Evangelist ARM

2. @janjongboom

Internet of Things

3. Developers

4. Limited world view
World is bigger than your pocket!
Interact with the physical world

5. From the internet of humans to
the internet of devices

11. Three problems
How to build smart devices?
How to discover devices?
How to interact with devices?

12. Discovering devices

13. Physical Web
Walk up and use anything

15. BLE beacons
31 bytes per packet
1 packet per second
7 years on an AA battery

16. Eddystone protocol

17. Movie poster
http://cinema/3281

20. Retail $4, Chipset $2

21. Interactivity

22. BLE is more than beacons
Battery service Heartrate service
Percentage
Capacity
Current HR
Max. detectable HR

23. Flying service
Direction and height characteristics

24. nRF Master Control Panel

29. Programming devices

30. Unstreamlined
Single-platform tools
No code sharing
Lack of libraries, documentation

31. (since 2009)
mbed

32. Online IDE
Code sharing
Single way of building for all targets

33. 91 boards supported
~200 staff working on it
170,000+ developers

34. Open source embedded platform
Operating system for microcontrollers
Rock-solid HAL and libraries (e.g. Bluetooth)

36. nRF51822
Nordic Semiconductors

38. Developing for mbed
C / C++ (not as scary as it sounds)
Large set of libraries
Solid Bluetooth stack

39. One year on AA battery 0.137 mA
0.020 mAmbed OS beacon
Eddystone, 1s interval, lowest power mode

42. Let's build some demo's!

43. Get hacking!

44. Thank you!
