Figure 8 The AOAA Board Network Interfaces
A number of very powerful applications open up when the Accessory no longer is an isolated system,
but instead a gateway to a networked system. The Android system no longer controls and interacts
with just a single device, but a complete network!
4.1.1 Industrial Use Case
Consider an industrial plant with a network of sensors diagnosing important components. It can for
example be vibration and temperature monitoring of electrical motors. By being able to correctly
diagnose and predict future failure of bearings and the motors in general, scheduled maintenance and
service can be performed. Scheduled maintenance can prevent costly production stops.
