Alright, I'm tired of googling. So I am working on a project which utilizes Windows Remote Arduino. I'm just starting so I am in the "just hack it together stage." The arduino is running standard firmata and I'm calling a sysex function which returns some data from some sensors.
I've subscribed to the StringMessageReceived Event, but what I'm finding is that event is not always firing. I 'should' be receiving data each time I send the sysex command. I did find a closed issue on the git hub site for remote-wiring that says to call the flush() on the firmata object, which I'm doing, but I'm not getting a 1 for 1 response.
Here's a sample output I'm getting.
Device Ready Event Fired

{\"temp1\":21.50,\"pH\":0.000}

I know the arduino is getting my commands, because I can see the LED's on one of my sensors processing the command.
Here's my UWP code.
public sealed partial class MainPage : Page
{
IStream connection;
RemoteDevice arduino;
UwpFirmata firmata;
DispatcherTimer timer;
public MainPage()
{
this.InitializeComponent();
}
private void btnConnect_Click(object sender, RoutedEventArgs e)
{
connection = new UsbSerial("VID_0403", "PID_6001");
firmata = new UwpFirmata();
arduino = new RemoteDevice(firmata);
timer = new DispatcherTimer();
firmata.begin(connection);
connection.begin(57600, SerialConfig.SERIAL_8N1);
arduino.DeviceReady += Setup;
arduino.DeviceConnectionFailed += ConnectFailed;
arduino.StringMessageReceived += StringRecieved;
timer.Interval = new TimeSpan(0, 0, 5);
timer.Tick += timerTick;
timer.Start();
}
private void timerTick(object sender, object e)
{
Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, ()
=>
{
lblPhData.Text += "Timer Tick!\n";
}
);
byte PH_QUERY = 0x44;
firmata.sendSysex(PH_QUERY, new byte[] { }.AsBuffer());
firmata.flush();
}
private void StringRecieved(string message)
{
Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, ()
=>
{
lblPhData.Text += message + "\n";
}
);
}
public void ConnectFailed(String message)
{
Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, ()
=>
{
lblPhData.Text += message;
}
);
}
public void Setup()
{
Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, ()
=>
{
lblPhData.Text += "Device Ready Event Fired\n";
}
);
}
private void btnGetData_Click(object sender, RoutedEventArgs e)
{
byte PH_QUERY = 0x44;
firmata.sendSysex(PH_QUERY, new byte[] { }.AsBuffer());
firmata.flush();
}
}
I've got to be missing something really really simple.
