I am programming a LaunchXL CC3200 board with the Energia IDE. If I run the WifiWebClient example all works as expected. However, if I change the server name to a host entry with a subdomain (i.e. e2e.ti.com) or my custom domain (iot.thinger.io). The client never connects. Seems to be a problem while resolving those hosts with subdomains. However, If i resolve the domain IP first in my computer, I can connect fine setting the IP address directly. So the DNS is not working fine here.
You can easily try changing the server host in the WifiWebClient to something like the following line, and it would not connect.
char server[] = "e2e.ti.com"; // name address for Google (using DNS)
This is the trace while loading the program (I think I have the firmware updated)
