DJI Bridge	Plugin to bridge native android DJI SDK and Cordova

dji-bridge

This plugin acts as a bridge between a cordova app and the android DJI SDK. It handles the connection to the SDK, keeps an updated telemetry list, and provides a test suite to aid in development.

Installation

Clone the repository from github

From a directory inside the cordova project run:

$ cordova plugin add {path_to_repository}
$ cordova prepare

Make sure the Android platform is already added to your cordova project Copy build-extras.gradle from the dji-bridge/hooks directory to the platforms/android directory of your cordova project

$ cp {path_to_repository}/hooks/build-extas.gradle {path_to_cordova_project}/platforms/android/

Add the required items to Manifest.xml in the platforms/android directory. See DJI documentation for reference: http://developer.dbeta.me/mobile-sdk/documentation/application-development-workflow/workflow-integrate.html#android-studio-project-integration

Supported Cordova Platforms

• Android 4.0.0 or above

Operation

DJI Bridge automatically connects to the DJI SDK service. Once the USB connection to the remote controller is connected, it automatically negotiates and begins capturing telemetry. Telemetry can be accessed from inside the cordova web page by polling the plugin.

//Check if drone is attached
plugin.attachToDevice(callback)

//Retrieve telemetry
plugin.getAttitude(callback)
plugin.getLocation(callback)
plugin.getStatus(callback)

//Turn sythentic data on or off
plugin.setTestMode(mode, cb)
