CCS/CC3200MOD: sl_NetAppDnsGetHostByName returning -161 (DNS undefined?)

Part Number:CC3200MOD

Tool/software: Code Composer Studio

Hi All,

I'm using the CC3200MOD for a project that sends a HTTP Post to a given webpage.  On some Wi-Fi's it has no problem looking up the hostname and getting the IP address.

On other WiFi systems it continually fails with -161 when executing the sl_NetAppDnsGetHostByName  function.

From looking at other posts, it seems -161 is caused by unknown/missing DNS.   Does this sound correct?  If so how do I define the DNS (such as google's 8.8.8.8 address?)

(I'm using MySimplelink as a reference and figure it can be done via a function call in the code or the Uniflash application, but I'm concerned my settings in uniflash might be wrong so please provide that information also.)

thanks,
Bob
