It looks like the cc3200 can only advertise a single parameter in the TXT record

Walt Wallach

Other Parts Discussed in Thread: CC3200

I have encoded the pText parameter to the NetAppMDNSRegisterService as described in the rfc's::

<\005>A=123<\006>B=4567<\000>

TextLen paramter is 13

The mdns packet on wireshark has a Txt Len of 14, and shows a siungle parameter with a length byte of 13 and my entire pText string, including the embedded length bytes.

Does the cc3200 support multiple parameters in an mDNS txt record? If so, how are they encoded? I tried issuing two calls to NetAppMDNSRegisterService, but the second fails (I expected that).

Hi Walt,

From your post I can't understand what is the exact string that you have attempted to register as a service.
A service should look something like this: "SimpleLinkPrinter553321._ipp._tcp.local"

We support up to 5 services, so you shouldn't have a problem registering two services.

Please refer to chapter 13 in our networking programmer guide: http://www.ti.com/lit/pdf/swru368

Another place to check is our mDNS example code that can be found in the CC3200 SDK installation: "<Install path>\cc3200-sdk\example\mdns"

Thanks,
Alon
