Hi guys,
I have a question abou the dns in lwip 1.3 (raw api)
I was using lwip 1.2 for a while (luminary - cortex) implementation, and glued a dns resolver that was available somewhere. It worked fine.
Now I am "upgrading" to 1.3, and started clean without my crap code. Actually , everything is working fine, except one thing:
Sometimes, the resolver does nothing. The call to dns_gethostbyname returns with ERR_INPROGRESS as expected, but the query packets are not sent and the callback function is never called, even after the timeouts... (everything else works, I can ping the interface, webserver is working, and so on). I noticed it only occurs if I call dns_gethostbyname right after initializing lwip (using fixed IP). If I use DHCP or I wait a few seconds after I set the static IP, it works sometimes. In the case of the fixed IP, do I have to wait something to begin sending data ? or am I missing some other initialization ?
Does anyone have an idea of what might be going on ?
Thanks!!
