Receiving and displaying data from Arduino

[Jaybird2203]

I have a slight problem getting my app to display a numeric value that is being sent by bluetooth from my arduino using the serial.print() command.

I can send data to another android that is running the exact same app and display that info properly, just having an issue with external information and I figure I'm missing something simple. Once I send the information from the Arduino, it causes the app to stop responding and crashes. Any help would be greatly appreciated.

On the Android I have

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("all_buttons_on")
   If AStream.IsInitialized = False Then
      AStream.InitializePrefix(Main.serial1.InputStream, True, Main.serial1.OutputStream, "AStream")
   End If
   
End Sub

and

Sub AStream_NewData (Buffer() As Byte)
   Dim received As String
   received = BytesToString(Buffer, 0, Buffer.Length, "UTF8")
   TemperatureLabel.text = received
End Sub

On the Arduino I have

float tempC;

Serial.println(tempC, 1);

As you can guess I'm attempting to have a temperature sensor send data to be displayed on the app.

You should not use InitializePrefix. You can only use this mode if both sides of the connection implement the "prefix" protocol.
