Hi,

 

I've noticed an interesting issue with the Netduino 3 (Ethernet) today. Thanks to TechnoGuy for pointing out I had posted in an old forum...

 

I deployed the same (unmodified) application code that runs perfectly fine on a Netduino Plus 2 onto the Netduino 3, and on the Netduino 3 it throws an exception in the code below. 

 

public DateTime GetNetworkTime(string hostName = "time-a.nist.gov")

{

            var hostEntry = Dns.GetHostEntry(hostName);

.....

}

 

An unhandled exception of type 'System.Exception' occurred in Netduino.IP.LinkLayers.AX88796C.

 

My Netduino Plus 2 has been upgraded to 4.3.2.1 and is using the new IP stack. I'm using Windows 7, VS2013 and using .Net MF SDK 4.3. 

 

Any suggestions?

 

Thanks.

After investigating further it appears that this issue is related to the time it is taking for the board to have a DHCP IP address allocated to it. i.e. The board (unless you wait for the network address to change) will have a default IP address of 0.0.0.0.
