WiFi fails during Scan or Join


#1

I have the following code:


        string ipAddress = "192.168.0.93";
        string nsk = "xxxxxxxx";

 
        void ProgramStarted()
        {
            try
            {
                wifi_RS21.Interface.Open();

                wifi_RS21.Interface.WirelessConnectivityChanged += new WiFiRS9110.WirelessConnectivityChangedEventHandler(Interface_WirelessConnectivityChanged);

                GHI.Premium.Net.NetworkInterfaceExtension.AssignNetworkingStackTo(wifi_RS21.Interface);

                WiFiNetworkInfo[] scanResults = wifi_RS21.Interface.Scan();
                WiFiNetworkInfo info = new WiFiNetworkInfo(scanResults[0]);
                wifi_RS21.Interface.NetworkInterface.EnableStaticIP(ipAddress, "255.255.255.0", "192.168.0.1");
                wifi_RS21.Interface.Join(info, nsk);


            }
            catch (Exception ex)
            {
                Debug.Print("ERRRRRRRRRRRR" + ex.Message);
            }
            Debug.Print("Program Started");
        }

During the execution of wifi_RS21.Interface.Scan(); I think it resets itself; if I’m lucky it will pass the scan and reset at the wifi_RS21.Interface.Join(info, nsk); and if I’m really lucky (and lately happens extremely rare) it just works.

One more thing: No error is thrown.

So, am I doing something wrong? If so, why does it sometimes work?

@ andre.m
The link from that topic goes to page that was moved and from there a link goes to this page
http://www.ghielectronics.com/docs/40/netmf-4.2-developer where the download link is missing :frowning:

@ andre.m - thank you.

I’ve installed the new version, but now nothing works; I’ve tried with a new empty project:

How do I change the firmware version to match managed code version?

@ allex4project

Can you use MFDeploy to tell us the firmware version that you are using?

Is your VS project targeting 4.1, 4.2 or 4.3?

@ mhectorgato -

4.2; I have VS2010; 4.3 isn’t in the list.

Your firmware needs to be updated. Please see this link for help to update your firmware: http://www.ghielectronics.com/community/forum/topic?id=11849
