btn1.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				
                // get Internet status
                isInternetPresent = cd.isConnectingToInternet();
 
		                // check for Internet status
		                if (isInternetPresent) {
		                    // Internet Connection is Present
		                    // make HTTP requests

								 if( SW1_flag == 0 ){
									 	DataCommand = "SW1onPackage";

								 }
								 else if(SW1_flag > 1){
										SW1_flag = 0;
										DataCommand = "SW1onPackage";
								 }
								 
								 SW1_flag++;
								 
								 Thread t = new Thread(new UDP_DataSend());
								 t.start();
