Cordovarduino

Cordovarduino is a Cordova/Phonegap plugin that enable you to use serial communication from an Android device to a serial over USB capable one.

It's a work in progress : Android to Arduino works, Arduino to Android now works.

Change log

2014.03: Ed. Lafargue Implemented read(). The success callback returns a Javascript ArrayBuffer which is the best way to handle binary data in Javascript. It is straightforward to convert this to a string if required - a utility function could be implemented in this plugin.

2013.11: Xavier Seignard First implementation

Install it

From the root folder of your cordova project, run :

cordova plugin add https://github.com/stereolux/cordovarduino.git
cp plugins/org.stereolux.cordova.serial/lib/usbseriallibrary.jar platforms/android/libs

How to use it

Thanks to usb-serial-for-android library, you can communicate with CDC, FTDI, Arduino and other devices. Here is the Cordova plugin API.

Because you're polite, first request the permission to use the serial port to the system:

serial.requestPermission(function success(), function error());

You can now open the serial port:

serial.open(opts, function success(), function error());

opts is a JSON object with the following properties:

• baudRate: defaults to 9600
• dataBits: defaults to 8
• stopBits: defaults to 1
• parity: defaults to 0

You're now able to read and write:

serial.write(data, function success(), function error());
serial.read(function success(buffer), function error());

data is the string representation to be written to the serial port. buffer is a JavaScript ArrayBuffer containing the data that was just read.

And finally close the port:

serial.close(function success(), function error())

Example

A callback-ish example.

var errorCallback = function(message) {
    alert('Error: ' + message);
};

serial.requestPermission(
	function(successMessage) {
    	serial.open(
        	{baudRate: 9600},
            function(successMessage) {
        		serial.write(
                	'1',
                    function(successMessage) {
                    	alert(successMessage);
                    },
                    errorCallback
        		);
        	},
        	errorCallback
    	);
    },
    errorCallback
);
