Support for fastboot and adb

fastboot is the preferred method of communicating with a bootloader. Brillo will use fastboot for all devices. ADB is the standard Debug Bridge used for debugging Android Devices and now Brillo devices.

Push updates to a device via the Cloud (OTA)

The Brillo OTA (over-the-air) update feature makes it easy for product developers to securely, reliably update products in the field. It enables the following scenarios:

  • Quickly address a serious bug or security problem.
  • Simplify your marketing and support by having nearly all products on the latest software.
  • Continue to add features to a product post-launch, keeping your users happy.

This page describes the entire update cycle for Brillo devices, from the developer creating an updated image to the product running updated software.

Basic audio support and an Audio HAL

Audio in and out support via a hardware abstraction layer (HAL) for all supported boards. We’ve added the Audio HAL tests to the Platform Test Suite (PTS).

Weave supported on devices

Weave is a communications platform for IoT devices that enables device setup, phone-to-device-to-cloud communication, and user interaction from mobile devices and the web.

Brillo’s support for Weave involves wrapping libWeave in a daemon (weaved)

Platform Test Suite will be the means of certifying a board. While the current suite of tests is growing, there is still a lot of work happening on the test framework. Stay tuned for future releases.

Open Sourced with Apache2 license

Using the default Android Open Source Project (AOSP) licenses for Brillo, we’ve decided to move all development to the open. Only certain aspects of Weave and new board bring-up will be developed within Google.
