MyColor

This is an app demonstrating an open BLE gateway and Accessors, two projects from http://lab11.eecs.umich.edu/. Check out the code for the app at https://github.com/lab11/accessors/tree/master/android .

At a high level:

This app will update the nearest hue light (with a bit of extra hardware attached to it) to the color you choose.

At a low level:

This app decodes URLs present in overloaded BLE advertisements. It then gets color data from the user and forwards that data to the received URL. The URL accesses the light through an Accessor runtime and updates the light to the received color.

Side note:

The acceptable colors for voice recognition are Blue, Red, White, Purple, Green, Mauve, Yellow and Orange.
Additionally, you can say off. Also, you can also specify a hex value with your voice by starting the 6 digit hex with either Ox or 0x.
