CCS/CC3220SF-LAUNCHXL: Resolve hostname MDNS

Akshit Singhal

Tool/software: Code Composer Studio

I'm running Avahi-Demon on RPi and I have it's hostname. When I'm trying to ping it using the network terminal example. It's giving me error

Server not able to authenticate answer/authority data

When I checked the source code I found out it's using the DNS to identify. But i need mdnsResolver.

Is there any API available for this?

I tried the example it's still gives out error "-6186" i.e No response for one-shot query.

Hi,

Meaning of error code is SLNETERR_NET_APP_MDNS_NO_ANSWER (No response for one-shot query). Please make sure that your MDNS service is working properly at your Raspberry Pi. For diagnosing issue you can use Wireshark.

Hi,

But ping (ICMP Echo) is not a mDNS.

I tried to resolve using Avahi-resolve, it was able to resolve it.

Hi,

Please use Wireshark and compare mDNS requests from computer and your CC3220. According this you should determine what is going on.
