In this chapter, you've been shown how application-layer standards can help you in your development by providing third-party infrastructure software you can use, as well as enabling them to interact with others without having to customize your code.
As you've seen, tightly-coupled interfaces are straightforward to implement. However, if you want to do something that goes beyond the interfaces that have already been established, it all becomes a bit tricky. All of the software interacting with your devices needs to be updated to take into consideration the new interfaces you create. If you want your interfaces standardized, it becomes even harder.
In this chapter, you've learned also learned the basics of CoRE, the LWM2M object model and IPSO Smart Objects. You've been introduced to the Leshan project and used it to publish sensor data and actuator control parameters using LWM2M. In the coming chapters, you will learn more about XMPP and how its loosely coupled IoT interfaces can be...
