Hi Rejean,
Yes, you are right!
I included the additional tmr calls, and dns retry is working.
What I am still wondering is why the UDP packets are not sent (in
about the first second after netif_is_up() says the interface is up).
I added a timed routine to send a small generic UDP packet each
200ms...the first 4 or 5 packets are not sent, and after that, all
packets are sent ok. That´s why the DNS kind of worked even without
the dns_tmr() if I delayed the dns_gethostbyname call.
I could live with that, but I would like to know what I am doing wrong.
Thansk again!!
Sergio.
