[Solved] mDNS - not re-advertised after TTL

[DavidDPD]

Are the mDNS API support to re-adversite after the TTL on their own, or does the user have to manually step up some kind of poller ? (I'm not super familiar mDNS spec itself.)

After about 5 minutes, the SDK 1.5 mDNS init seems to withdraw itself, and not re-advertised it.

Code: Select all

> dns-sd -B _chatFabric
Browsing for _chatFabric._tcp

I actually figured out this issue. This was a usage issues.

Especially on Mac OS X and iOS ... the service name (badly named in the ESP SDK as mdns_info->server_name ), needs to be a registered in /etc/servers for the dns-sd tool send the QM/QU mDNS multicast questions/queries on the ethernet. Once I moved this to a known server, the Apple stuff finally started to ask the questions, and the EPS SDK mDNS APIs, do correctly reply.

So, i think I solved my own issue.
