Non-blocking Internet connection

Hi,

is there any way to achieve a non-blocking Internet connection when using 

Ethernet.begin(mac, ip);

?

If there is no connection at all, this procedure does not block, but if there IS and the IP is incorrect, the program stops at this point.

Is there a workaround?

Hi Didier,

my problem is different. Let's assume THERE IS a working Internet connection, which, after some time, stops working for whatever reason. There is an Ethernet module present, but the Ethernet.begin method blocks the running of the program because there is a problem with the Internet connection and pretty much freezes the Industruino.

Hi Peter, At this point, I would use a watchdog, count the times the Industruino freezes in a row, save this in EEPROM, and when I reach a limit like 3 retries, stop retrying for, say, 10 minutes, and try again another 3-tries cycle, until it works. Not very satisfactory, but works. Didier, DG2R

Hi Peter,

I think Tom covered this in : https://industruino.com/blog/our-news-1/post/ethernet-easy-plug-play-38 when he tests if the Ethernet module is present prior to sending his Ethernet.begin by testing if the SD client is present, if I remember well.

Hope this helps

Didier, DG2R
