Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/957

Working in the development branch:

I found a reference (in a comment) in the script referring to using a static IP, and I also dug in the source code a bit:

github.com/tzapu/WiFiManager@9a85b107fa/examples/Advanced/Advanced.ino (L52)

Am I correct in my understanding that to use this it should get set before calling wm.autoConnect(ssid, pwd); and that doing so will auto-connect to the configured access point with that IP information instead of using WiFi.config(ip, gw, sn, dns);?

I also saw:

wm.setShowStaticFields(true); // force show static ip fields
wm.setShowDnsFields(true);    // force show dns field always

The implication there is I don't have to set up custom fields to configure static IP and DNS (yay!). What's not clear is whether those fields autosave anywhere or if I need to save them manually. If the latter, how do I access the field values to save? If they are auto-saved, how do I access them initially to set the setSTAStaticIPConfig() call?

I looked through all the rest of the examples as well as chased it a bit through the source code but did not find my answer. The core documentation was likewise not helpful. I got as far as ESP8266WiFiGenericClass::persistent() and then got lost. Hopefully I didn't miss an obvious answer to this.

"Seems like" that's how it works - that setShowStaticFields(true) will allow setting a static IP and that setShowDnsFields(true) allows setting a DNS server. Further, somehow, ESP8266WiFiGenericClass::persistent() saves that off automagically. It seems like there's no need to use setSTAStaticIPConfig() when this is done.

Hopefully, that's correct. It seems to work anyway.

The esp will not remember static or ip info you will have to save it and restore it

Understood, thanks. I was just cleaning up an old issue.
