The project from git contains only the Cordova code. The BLE plugin and iOS or Android platform needs to be installed into the project before running.
$ cd cordova
$ cordova plugin add com.megster.cordova.ble
$ cordova plugin add org.apache.cordova.console
$ cordova platform add android
$ cordova run android --device
$ cordova platform add ios
$ open platforms/ios/BLE\ Lock.xcodeproj
Plug in your iPhone. Choose the target device in Xcode. Build and deploy through Xcode.
You can modify the application by editing the files in $PROJECT_HOME/cordova/www.
Make sure you run cordova prepare before redeploying the app through Xcode.
