Hi,

We are developing a standalone tizen wearable web app for Samsung Gear S2.

We need to incorporate Host Card Emulation functionality in it.

We have followed the link

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

https://developer.tizen.org/development/guides/web-application/tizen-features/communication/nfc

When we deployed the application to Gear S2, the control does not come to addHCEEventListener() function.

JS code

( function () {
  
	var hceListenerId = 0;
	var adapter = tizen.nfc.getDefaultAdapter();
	try {
		adapter.cardEmulationMode = "ALWAYS_ON";
	}
	catch(e)
	{
		console.log(e.name + ":  " + e.message);
	}
	
	try {
			hceListenerId = adapter.addHCEEventListener(function(event_data)
			{
			   if (event_data.eventType =="ACTIVATED")
			   {				  
				   window.alert("HCE activated");
			   }
			   else if (event_data.eventType =="DEACTIVATED")
			   {				   
				   window.alert("HCE deactivated");
			   }
			   else if (event_data.eventType =="APDU_RECEIVED")
			   {				  
				   window.alert("APDU received");				  	 
			   }
			});	
	}
	catch (error)
	{
		console.log("AddHCE Exception - " + error.name + ":" + error.message);
	}
} () );

config.xml

</widget>

Is wallet.xml needed for this. We have given this but we do not know the significance of this. Can anybody help on this?

Is HCE supported in wearable web?

Or is there any steps that we missed.

Thanks in Advance
