Thank you for fixing that bug !

@d-a-v

Should this also be enabled for open-sdk lwipopts.h?

[d-a-v]

@someburner
Yes of course.

I was only looking at my esp-open-sdk ongoing obsolete PR,
I wasn't aware of your repository https://github.com/someburner/esp-open-sdk/tree/sdk2-lwip212.
Will you make a PR on esp-open-sdk from yours ?

I will update the ARP thing for esp-open-sdk to avoid a PR here.

(edit: done)

@d-a-v , I've sent you a follow up email sometime ago after the PR, that the builder link in https://github.com/esp8266/Arduino/tree/master/tools/sdk/lwip2 is still wrong and points to a previous version, I've resent the email now.

@aboulfad You seem to be right. Arduino repository doesn't point to the right commit.

Thanks. I haven't made the PR to esp-open-sdk yet since pfalcon hasn't provided any guidance on what to do about sntp, but I could ask again. I have my own SDK in order to use more recent versions of GCC.

[d-a-v]

Is it the esp-sntp.c ? We can put it back here if needed but I guess you have one for your repository
Per pfalcon/esp-open-sdk#271 (comment) I think you'd just need to use them (esp-sntp.c, esp-millis.c) in the open Makefiles and prpose a PR.
