Hi Simon, Thanks. As Rejean pointed out, the LuminaryMicro implementation of lwip misses the dns_tmr() call. I fixed it and now dns retry is working, although all UDP packets only are generated on the wire about 1 second after netif_is_up() says interface is up.
Do you have an idea of what I am doing wrong ? Regards, Sergio.
