WiFi RedPine Exception when trying to run the demo

Im trying to run the WiFi Demo:

http://www.ghielectronics.com/downloads/NETMF/Library%20Documentation/html/7481f4d9-b4bc-f53d-e6bb-3a1ae861c9ef.htm

IM getting this output:

There is a known issue with this component. Search the forum and you’ll find plenty of details. A new SDK is supposedly close to release to resolve this.


#3

When will the SDK be ? anyway of resovling this issue ?


#4

You and me both (+ others) want to know the answer to the first question. GHI is waiting on an impending firmware update from RedPines. The answer to the second question is wait for the update.


#5

Wait… man im in the middle of making my thesis the deadline is to january, and I have the WiFi, and other stuff but the WiFi is crucial for the communication :/. Hurry up with that SDK guys ;(


#6

The exception you are getting is not related to the bugs we are fixing. Please let me see the code you are using in your project and take a picture of how you connected the wifi module to your board. It is FEZ Cobra isn’t it?

    }
}

And i made a board which is consistant with the atached schema. (Plus i have two capacitors of course :slight_smile: 220uF electrolyte + .47 uF).

I checked the board like couple of times - it seems ok + i get a green LED put on and off when the debug is caught.

With an error Code 2 - then Then catches the exception ( when moving into )

HELP ME OUT PLZ

Yes its Fez Cobra + I attached a photo but you will get more out of it from the schematic I added earlier
I’m Waiting for any helpy


#10

Common Guys …

Any ideas ? Suggestions ? this is the backbone of my Thesis :frowning: the deadline is near…


#11

OK

I use the UEXT connector,

I noticed that when i accidently switched it to SPI2 - the LED went on and it tried to Update The Firmware, but when in SPI1 i get an exception to check the hardware connections PLZ Help me


#12

Oki,

Make sure you have the latest firmware on your board and latest SDK installed. Also make sure your references in your code are ok… if not sure, remove them and add them again…

I aslo use a redpine module on a custom board and that works properly in combination with EMX, but sometimes also receive exceptions, for example in WiFi.Scan(…) or others.

If you receive an exceptions from WiFi or Network related methods, simply try the call again.
like:


 AccessPointInfo[] accessPointInfo = null;
            int retryCounter;
            for (retryCounter = 0; retryCounter < 10; retryCounter++)
            {
                try
                {
                    accessPointInfo = WiFi.Scan("yourSSID");
                    if (accessPointInfo != null && accessPointInfo.Length != 0)
                        break;
                }
                catch (Exception ex)
                {
                    DebugHelper.DebugPrint("Wifi Scan Exception: " + ex.Message);
                    continue;
                }
            }
            if (retryCounter == 10)
            {
                RouterLed.Blink();
                Thread.Sleep(Timeout.Infinite);
            }

            for (retryCounter = 0; retryCounter < 10; retryCounter++)
            {
                try
                {
                    WiFi.ConnectInfrastructure(accessPointInfo[0], Configuration.Settings.PassPhrase);
                    break;
                }
                catch (Exception exception)
                {
                    DebugHelper.DebugPrint("Wifi Connect Exception: " + exception.Message);
                    Thread.Sleep(100);
                }
            }


#13
WiFi.UpdateFirmware(WiFi.HardwareModule.RS9110_N_11_21_1_Compatible, SPI.SPI_module.SPI1, (Cpu.Pin)2, (Cpu.Pin)26, (Cpu.Pin)3);//EMX DevSys
                        WiFi.Enable(WiFi.HardwareModule.RS9110_N_11_21_1_Compatible, SPI.SPI_module.SPI1, (Cpu.Pin)2, (Cpu.Pin)26, (Cpu.Pin)3);//EMX DevSys
 

This configuration matches the UEXT pin mapping on EMX Dev Sys only.

Please change the configurations according to how you wired the signals. I think this might work:

WiFi.UpdateFirmware(WiFi.HardwareModule.RS9110_N_11_21_1_Compatible, SPI.SPI_module.SPI2, (Cpu.Pin)2, (Cpu.Pin)26, (Cpu.Pin)3);// FEZ Cobra
                    WiFi.Enable(WiFi.HardwareModule.RS9110_N_11_21_1_Compatible, SPI.SPI_module.SPI2, (Cpu.Pin)2, (Cpu.Pin)26, (Cpu.Pin)3);// FEZ Cobra

For more information take a look ath Enable() and UpdateFirmware() mothod detailed documentation.

If the Green LED goes on on the module then it is enabled.
