The document discusses the challenges of developing Internet of Things (IoT) applications, emphasizing the slow iterations of hardware deployment and the difficulties associated with firmware and testing. It introduces MQTT as a lightweight messaging protocol for IoT devices, supporting various communication needs and highlighting the importance of a reliable app platform for managing data and connectivity. The author concludes by stating that the IoT is still in the early stages of development.

3. IoWTF

4. Electronic Frontiers
Sensors Everywhere

6. Free standing / embedded sensors
Battery Powered
Run on unreliable networks
Be mobile
Be small
Be secure

7. when you come from software
Hardware is Hard

8. Hardware
Iterations are very slow
“Deployment” of a PCB design takes 2-3 weeks
Component availability is often uncertain
Pricing is based on volume

9. Firmware
Tooling is expensive, proprietary, primitive
There is no Filesystem
Delivery of new releases is difficult / impossible
Testing has to happen in-device

10. OMG!

11. What about …?

12. Connecting

13. Ubiquitous WiFi?
Chips remain comparatively expensive
Power consumption isn’t low enough
SSL Support is a rarity
Wearables and automotive aren’t in your WiFi
range

15. MQTT
Lightweight messaging protocol
Low bandwidth == Low power
Publish / Subscribe
security through SSL

16. Publish Subscribe Device API

17. What we do on the Platform
Routing
Conditional logic (filtering)
Stateful rules engine
Autonomous event handling

18. Working with the data app APIs
RESTful API for discovering device state
Realtime feeds for “noisy sensors”
Notifications for slow feeds
Device description lookups (apicommons)

19. Hardware is not the new Software
The Internet of Things
isn’t here yet.
