Read Arduino Serial with bluetooth 4.0 using Evothings

I'm developing an application, where I want my iPhone to touch information with the Arduino from bluetooth 4.0. I was able to connect to bluetooth and I can also send data through Serial, but I can not read Serial data. I used the example of evothings arduino-ble as a base, I changed the linha 166 of the app.js file as shown below:

startReading: function(deviceHandle)
{
   console.log('Enabling notifications');

   // Turn notifications on.
   app.write(
      'writeDescriptor',
      deviceHandle,
      app.descriptorNotification,
      new Uint8Array([1,0]));

   // Start reading notifications.
   evothings.ble.enableNotification(
      deviceHandle,
      app.characteristicRead,
      function(data)
      {
         //document.getElementById('dados').innerHTML = data;
         app.drawLines([new DataView(data).getUint8(0, true)]);
      },
      function(errorCode)
      {
         console.log('enableNotification error: ' + errorCode);
      });
},

And I also changed the values of caracteristic to the specific values of my bluetooth in linha 230 of app.js

getServices: function(deviceHandle)
{
   console.log('Reading services...');

   evothings.ble.readAllServiceData(deviceHandle, function(services)
   {
      // Find handles for characteristics and descriptor needed.
      for (var si in services)
      {
         var service = services[si];

         for (var ci in service.characteristics)
         {
            var characteristic = service.characteristics[ci];
            var resultado="";
                for (propriedade in characteristic) {
                  resultado += propriedade + ": " + characteristic[propriedade] + "\n"; 
                };
                document.getElementById('carac').innerHTML = resultado;

            if (characteristic.uuid == '0000ffe1-0000-1000-8000-00805f9b34fb')  // This line changed for HM10
            {   document.getElementById('funcao').innerHTML = "entrei 1 if uuid carac";             
               app.characteristicRead = characteristic.handle;
            }
            else if (characteristic.uuid == '0000ffe1-0000-1000-8000-00805f9b34fb')  // This line changed for HM10
            {
                document.getElementById('funcao').innerHTML = "entrei 2 if uuid carac";
               app.characteristicWrite = characteristic.handle;
            }

            for (var di in characteristic.descriptors)
            {
               var descriptor = characteristic.descriptors[di];

               if (characteristic.uuid == '0000ffe1-0000-1000-8000-00805f9b34fb' &&  // This line changed for HM10
                  descriptor.uuid == '00002902-0000-1000-8000-00805F9B34FB')
               {
                  app.descriptorNotification = descriptor.handle;
               }
            }
         }
      }

      if (app.characteristicRead && app.characteristicWrite && app.descriptorNotification)
      {
         console.log('RX/TX services found.');
         app.startReading(deviceHandle);
      }
      else
      {
         console.log('ERROR: RX/TX services not found!');
      }
   },
   function(errorCode)
   {
      console.log('readAllServiceData error: ' + errorCode);
   });
},

But it did not work and returns me Disconect in the "Status" field of the application. Can anyone help me solve this problem?
