WiFiRS9110 on a G120E Dev Board

NETMF & Gadgeteer

The only way I have found to use the WiFiRS9110 is to set it up in MAIN() .

I have tried using 4.3.7.10 and 4.3.8.0 and the exception is the same when moving out of Main()

If I move my code outside of main I always receive a hardware timeout exception.

(Not blaming the G120E Dev Board because I seem to recall having this problem using other boards in the past)

Is there a way around this exception? I would like to use the WiFiRS9110 much later in the application.

If nothing else… I would like to know why the code must be in Main()

Thanks!

I have the WiFiRS9110 module being setup in a thread on a G120 and it works fine.

I have a global for it but the actual assignment is done in the thread,

@ willgeorge - Can you post a small example just to be sure?

@ John -

Here you go!

This will run if in Main

This would not be the final code. For now it is just minimum code to see if I can get it to run outside of Main()
I can receive the time for awhile but at some point it stops. (I can fix this issue later)



if (usingWifi)
{
	try
	{
		wifi = new WiFiRS9110(SPI.SPI_module.SPI2, myWiFi.SPI_CS, myWiFi.SPI_INTR, myWiFi.WIFI_RESET);

		if (!wifi.Opened)
		{
			wifi.Open();
		}

		if (!wifi.NetworkInterface.IsDhcpEnabled)
		{
			wifi.NetworkInterface.EnableDhcp();
		}

		if (!wifi.NetworkInterface.IsDynamicDnsEnabled)
		{
			wifi.NetworkInterface.EnableDynamicDns();
		}

		wifi.Join(mySSID, myPassword);
	}
	catch (Exception e)
	{
		Debug.Print("wifi " + e.Message);
	}
	//

Methods outside of main()


private static void Program_OnInterrupt_LEFT(uint data1, uint data2, DateTime time)
{
	Thread TesterThread = new Thread(Tester);
	TesterThread.Start();
}
//

public static void Tester()
{
	if (wifi == null)
	{
		wifi = new WiFiRS9110(SPI.SPI_module.SPI2, myWiFi.SPI_CS, myWiFi.SPI_INTR, myWiFi.WIFI_RESET);

		wifi.Open();   // FAILS ON OPEN with hardware timeout exception

		wifi.NetworkInterface.EnableDhcp();
		wifi.NetworkInterface.EnableDynamicDns();
		wifi.Join(mySSID, myPassword);
	}
}
//

@ willgeorge - The following program worked fine for me. (Rename Main1 and Main2 as appropriate.)


using GHI.Networking;
using GHI.Pins;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using System.Threading;

public class Program {
	public static void Main1() {
		using (var netif = new WiFiRS9110(G120E.SpiBus.Spi2, G120E.Gpio.P3_30, G120E.Gpio.P2_30, G120E.Gpio.P4_31)) {
			netif.Open();
			Debug.Print("Passed.");
		}
	}

	public static void Main2() {
		var input = new InterruptPort(G120E.Gpio.P2_21, true, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeLow);

		input.OnInterrupt += OnInterrupt;

		Thread.Sleep(-1);
	}

	public static void OnInterrupt(uint data1, uint data2, System.DateTime time) {
		new Thread(Tester).Start();
	}

	public static void Tester() {
		using (var netif = new WiFiRS9110(G120E.SpiBus.Spi2, G120E.Gpio.P3_30, G120E.Gpio.P2_30, G120E.Gpio.P4_31)) {
			netif.Open();
			Debug.Print("Passed.");
		}
	}
}

@ John -

Thank You …

I will try it ASAP (Baby sitting at the moment)

As a note only. I used my code on my G400-D Dev Board and it worked fine.
