Mastering Internet of Things

Aggregating capabilities

Since we're going to communicate with our Arduino using a USB serial port, we must make a declaration in the Package.appxmanifest file stating this. If we don't do this, the runtime environment will not allow the app to do it. Since this option is not available in the GUI by default, you need to edit the file using the XML editor. Make sure the serialCommunication device capability is added, as follows:

<Capabilities> 
   <Capability Name="internetClient" /> 
   <DeviceCapability Name="serialcommunication"> 
         <Device Id="any"> 
               <Function Type="name:serialPort" /> 
         </Device> 
   </DeviceCapability> 
</Capabilities>
