Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/921

Using development branch at 34d9a975b5

Once wifi is connected, I'd like to still be able to access the configuration menu to change stored credentials and sa "/update" or something. Would it be possible to have an ESP8266WebServer.h .on() configuration to pass any clients accessing "/update" to WiFiManager to change configs?

Thanks

There is an ondemand webportal example.

It seems in that example that an event triggers the AP to enable as if autoConnect failed. I'd like to be able to use a custom URI to access the WiFimanager config page to be able to modify my WiFiManagerParameters on the fly without running the whole AP to do so, using a URI on an existing instance of ESP8266WebServer. I know this is probably nontrivial. Maybe just running WiFiManager config server on a different port instead?

Literally what it does.

If you want advanced stuff like adding routes check the dev example

Yes, but I can't merge my own URI handlers with that. Can you add some HTTP server options so I can pass in my own URIs and function pointers for handling them? Or make server public so I can access it? Would that work?

DEV/ example, look in the code!

wm.setWebServerCallback(bindServerCallback);

void bindServerCallback(){
  wm.server->on("/custom",handleRoute);
  // wm.server->on("/info",handleRoute); // can override wm!
}

void handleRoute(){
  Serial.println("[HTTP] handle route");
  wm.server->send(200, "text/plain", "hello from user code");
}

@tablatronix commented on GitHub (Aug 18, 2019): DEV/ example, look in the code! ```C++ wm.setWebServerCallback(bindServerCallback); void bindServerCallback(){ wm.server->on("/custom",handleRoute); // wm.server->on("/info",handleRoute); // can override wm! } void handleRoute(){ Serial.println("[HTTP] handle route"); wm.server->send(200, "text/plain", "hello from user code"); } ```

Thanks! I was looking at the wrong example, sorry about that.

How can I get my parameters to show up after wm.startWebPortal()? I don't see anything that seems to remove them. If I forcibly re-add them prior to startWebPortal, they still don't show up on the /wifi page.

Here's what I'm using:

wm.stopConfigPortal();
wm.startWebPortal();

I do see *WM: [0] [ERROR] WiFiManagerParameter is out of scope when I load the page though. Thanks for your help.

You will probably have to change the scope of wm obj.

WiFiManager wm; to global outside of a function/setup for example

That solved it. Thanks.

One last issue with this...

When using startWebPortal(), it starts the DNS server as well. Can you add a function or modify the code so that the web portal can be started without DNS as well since it's not needed (in this case)?

Thanks.
I was using the library available in Arduino. Didn't know that it was outdated.
After pulling the latest source directly from github it was working as expected.
