Tizen Developers

Hello,

1)

This guide would be helpful for NFC read/write you want to perform:

NFC: Managing an NFC Device and Detecting NFC Tags and Peers

https://developer.tizen.org/development/tutorials/web-application/tizen-features/network/nfc

Additionally, I am just giving you a summary of how to do a read/write operation between NFC devices.Please go through the document for more details level implementation or to implement other available features.

At first make the NFC on.

Samsung GearS2 ->Settings->Connections-> NFC->On

/*Add privileges in config.xml  */

<tizen:privilege name="http://tizen.org/privilege/nfc.p2p"/>

/*.....
  Similary all the required privileges*/

/* NFC peer connect example*/

var adapter = tizen.nfc.getDefaultAdapter();

 var onSuccessCB = {onattach : function(nfcPeer) {
     console.log("NFC Target is detected");
   }, ondetach : function() {
     console.log("NFC Target is detached");
   }};
   
 adapter.setPeerListener(onSuccessCB);
 
/* Build & send Message example*/

var newMessage = new tizen.NDEFMessage();

var newRecord = new tizen.NDEFRecordText(“Hello Tizen”, en-US);
newMessage = new tizen.NDEFMessage(); 
newMessage.records[0] = newRecord;

Peer.sendNDEF(newMessage);


/* Recieve Message example*/

function readMessage(message)
{
    console.log("Record Count is " + message.recordCount );
}
Peer.setReceiveNDEFListener(readMessage);

To connect directly to a WiFi network:  

Firstly make the WiFi on.
