Pair Bluefruit with Google Glass

By default the Google Glass can only act as a slave device that be paired to your tablet or phones as an accessory. But it can also behave as a master device that search and connect to other devices.

This method is first revealed in Voiding Your Warranty: Hacking Glass session at Google I/O. If you want to go straight to see how it works, you can use this link.

In order to access to settings panel, first you need a working Android SDK, you can refer to this GDK tutorial.

Then you need to install two apps by typing following command to install them:

  • adb install Settings.apk
  • adb install Launcher2.apk

However Google did not release the two apks officially. But Jeff did some research on it and compiled these two apks and released them on his blog. You can either download from his site or download the following zip file.
After your installation of Settings and Launcher2. you can swipe all the way left to settings.
Tap your trackpad you will see the Launcher option. Do not check "Use default for this action"or you can not access the other option until you uninstall Launcher2.apk
In Launcher you will see the classic Android home screen. Click the All Apps button.
In All apps screen, you will see three Apps. "Glass Home" will take you back to Google Glass home screen. "Launcher" will show the Android home screen again and "Settings" will lead to settings panel.
In settings panel you can choose "Bluetooth" to pair Bluefruit. You can also go to "Display"->"Sleep" to keep screen on longer without interaction.
Then you can search and pair devices just like you are using a regular Android device.
