Project Brillo is the codename for a developer preview of an
Android-based
embedded operating system platform by Google, announced at
Google I/O 2015. It is aimed to be used with low-power and memory constrained
IoT devices. It will support
Bluetooth low energy and
Wi-Fi. Along with Brillo, Google also introduced the Weave protocol [https://developers.google.com/brillo/?hl=en], which Brillo devices will use to communicate with other devices and which it hopes will be adopted by other IoT operating systems.
