Hi guys.
I’m struggling to get HTTPS to work on the FEZ raptor. I have it working fine on the old FEZ spider board, but th exact same code on the raptor fails. both are using the latest firmware (SDK 2015, net MF 4.3 QFE2). both use the ENC28 ethernet module.
I have updated the SSL seed in both modules using MFdeploy
I have posted a simplified code snippet below. if somebody could try it and let me know if it succeeds on their device, I would really appreciate that.
if (Initialise_Ethernet_FEZRaptor_port1())
// if (Initialise_Ethernet_FEZspider_port6()) // uncomment to use FEZ spider
{
try
{
makeGenericHTTPRequest(); // this succeeds on both devices
getLatestTime();
makeHTTPSRequest(); // this hangs infinitely on the raptor and never ever returns.
}
catch (Exception ex)
{
Debug.Print(ex.Message);
}
}
}
private static void makeHTTPSRequest()
{
string url = "https://www.ghielectronics.com";
using (var req = System.Net.HttpWebRequest.Create(url))
{
using (var res = req.GetResponse())
{
Debug.Print("HTTP Response length: "
+ res.ContentLength.ToString());
}
}
}
private static void getLatestTime()
{
TimeServiceSettings settings = new TimeServiceSettings();
settings.ForceSyncAtWakeUp = true;
settings.RefreshTime = 1800; // in seconds.
IPAddress[] address = Dns.GetHostEntry("pool.ntp.org").AddressList;
if (address != null && address.Length > 0)
settings.PrimaryServer = address[0].GetAddressBytes();
address = Dns.GetHostEntry("time-a.nist.gov").AddressList;
if (address != null && address.Length > 0)
settings.AlternateServer = address[0].GetAddressBytes();
TimeService.Settings = settings;
// Add the time zone offset to the retrieved UTC Time (in this example, it assumes that
// time zone is GMT+1).
TimeService.SetTimeZoneOffset(60);
TimeService.Start();
