(1)Google I/O 2015 Keynote 完整紀錄
(2)Brillo官網上的An Introduction to Brillo, the OS for IoT
根據TechOrange科技報橘 沈孟學 - 【年度祭典！Google I/O 現場報導】Google 物聯網平台 Brillo 來了，能讓物體「溝通」更智慧嗎？ 裏面, 也是摘錄自Google I/O的簡介, 說了, 使用Brillo作業系統裝置的三大特性.
·智慧：不管使用者是從辦公室回家、或是周末悠閒待在家裡，運行 Brillo 作業系統的裝置都能做出準確的反應，讓使用者享有便捷、智慧的使用體驗。此外，輕鬆分享讓使用者可以提供客人一個專用的暫時性無線網路，或是暫停已啟用的 Smart Lock。
·簡單：Brillo 的啟用設定相當簡單，而且每一台 Android 裝置都有內建自動偵測。「Android On」應用程式可以協助使用者將所有裝置連線，在一個地方功能即可輕鬆、簡單地管理所有的裝置。
·同步：使用者不會被限制於某一品牌的裝置，只要是搭載「Android On」應用未來在例如 Nest 或 Homekit 等其他平台的裝置也將能運作程式的裝置皆可順暢運作。
另外還有一個名詞要注意: Weave - 簡單說就是Brillo Device之間溝通的protocol.
在官方的說法, Brillo的硬體需求為32MB的記憶體, 128M的系統儲存空間, 老實講這樣子的需求對IoT裝置來說, 太高了吧!
因為Brillo已經Release出來了, 當然就要抓下來看看長的是圓是扁囉!
底下的過程我也是參考How to Build Brillo Operating System from Source Code and Run Brillo Emulator
步驟1:
下載Brillo Source Code, 這裏是針對branch brillo-m7-release下載
repo init -u https://android.googlesource.com/brillo/manifest -b brillo-m7-release
步驟2:
