Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/31

I read this somewhere, maybe in the source code, I cant remember.

I get a

Entered config mode
0.0.0.0
*WM: 
*WM: Configuring access point... 
*WM: ESP457230
*WM: AP IP address: 
*WM: 0.0.0.0
*WM: HTTP server started

And my AP is never available to devices.

Do you know what causes this ?

delay(500); // Without delay I've seen the IP address blank

hmmm

hi, tried it with delay?
never seen it like this in the non modified framework, maybe due to the new callback?

maybe try the simplest autoConnect example

hi,

i ve just noticed this happening if i have
wifiManager.resetSettings(); in code.

do you have that function call in your code?

I forgot I added a delay in setup() for debugging something to make sure a pin was low before starting up stuff.

setup(){
delay(200);

It must be doing some init blocking, which is odd.. But it is probably in the main esp8266 library, so ill close this.

it s very odd, i have noticed this happens when i do WiFi.disconnect() and have a delay after.
with no delay after disconnect, everything works fine
quite weird indeed

Yeah and I cannot reproduce yet with a simple test. ( no wifimanager)

With delay(100) it works again, i am gonna guess this is a race condition against the esp8266 libs auto connect.

This says that it will auto connect if there is a stored SDK settings

well, i got a minimum sketch to replicate this without WiFiManager
better report it to esp8266 arduino

#include <ESP8266WiFi.h>

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  WiFi.disconnect();
  delay(200); //this delay, if you comment out it all works, if left, softAPIP returns 0.0.0.0
  WiFi.mode(WIFI_STA);
  WiFi.begin("", "");
  int connRes = WiFi.waitForConnectResult();
  WiFi.mode(WIFI_AP);
  //assuming connecting failed
  WiFi.softAP("asdfghj");
  delay(500); 
  Serial.println("");
  Serial.println(WiFi.softAPIP());
}

void loop() {
  // put your main code here, to run repeatedly:

}

I added a

void setup() {
    WiFi.mode(WIFI_OFF);  
    delay(200);

to fix for now.

Of course i think that workaround also breaks STA connections, i think this is an issue with dhcp client and servers starting up, either way someone smarter can look at the issue I created and figure it out.

Thanks

this seems sorted with the latest github changes and sdk 1.5.1
