Hi together,
I am a newbie wit Arduino and am really impressed about the possibilities. Within my first project I set the clock of a TinyRTC modul once a day over NTP to the correct time and show it on a LCD. Everything works fine when the ethernet cable is connected to the board. If not, the sketch stops at "if (Ethernet.begin(mac) != 0) .." till the timeout is over.
My question is now if it is possible to check if a cable is pluged before starting to configure the ethernet connection? I have searched for I little while now but can't find a hint.
Thx for the help and excuse my bad englisch
Greetings,
Frank
