Once it is installed you can go ahead and open the Netduino project (from the previous section) again, then follow these steps: 1. We could create the phone project in the same solution as the Netduino project, but in terms of debugging, it's easier to have them in separate instances of Visual Studio. So open up another copy of Visual Studio and click on File | New | Project. Find the Windows Phone App template by navigating to Installed | Templates | Visual C# | Windows Phone. Name the project and then click on OK to create it.

Any Windows Phone 8 device can be used, as they all have Bluetooth. The project setup The setup for this project is extremely basic because we are just connecting the Bluetooth module and nothing else. Once our phone is connected we will use it to control the onboard LED, however, you can expand this to control anything else too. The Bluetooth module you buy may look slightly different to the diagram, but not to worry, just make sure you match up the labels on the Bluetooth module (GND, 3-3V or VCC, TX, and RX) to the diagram.

The second last method you need to add is the one that will wait for the data to be received. It is an asynchronous method, which means that it can have a line within it that blocks execution (for instance, in the following code the line that waits for data will block the thread), but the rest of the app will carry on fine. ReadAsync(bytes. Substring(str. Show("There was a problem"); } finally { WaitForData(socket); } } Yes, this code looks complicated, but it is simple enough to understand. First we create a new byte array (the size of the array isn't too important, and you can change it to suit your application), then wait for data to come from the Netduino.
