Networking was once an expensive technology for connecting large computers systems. But as costs have dropped, networking has become an integral aspect of most embedded systems. Wired Ethernet, WiFi, and Bluetooth have become the primary interface port for even the smallest processors. This technology shift has been dubbed Internet of Things (or IoT). But like most tongue-in-cheek labels, this carries negative connotations of toasters with webpages. The networking revolution has been developing for many years long before it reached the popular press.
In truth, adding a network port to an embedded device is often a cost-effective approach to provide communications and control. The bonus is that networking often can have unexpected benefits by enabling integration options.
