Adafruit Android BLE UART
Example code for interacting with a Bluefruit Bluetooth LE UART in an Android application. Run the application and it will connect to the first available Bluetooth LE UART found to provide a simple console for sending and receiving data. Try testing with a Bluefruit LE configured to run the echoDemo!
This code requires the latest version of Android Studio (0.8 beta) to build. Download the repository and use the 'Import project...' option to load the directory as a project in Android Studio. The code will not work with the legacy Eclipse-based ADT build environment!
Warning: This is alpha/beta quality software and only serves as an example of how to use a Bluetooth LE UART in an Android application! Bluetooth LE support is somewhat flakey in Android so it is highly recommended that you upgrade to the absolute latest version of Android possible (ideally 4.4.4+) and use hardware that is known to be somewhat reliable like a Nexus device.
