Hardware: ESP-12e, esp01, esp25

ESP Core Version: 2.4.0, staging
SDK Version 2.2.1
Core version 2.4.1
Boot version 4

Description

I am using autoconnect and callbacks, to connect to a stored WiFi SSID. In callback I am putting static IP 10.0.1.1 for the config portal.
myWiFiManager->setAPStaticIPConfig(IPAddress(10,0,1,1), IPAddress(10,0,1,1), IPAddress(255,255,255,0));

If Wifi does not connect because I do a resetSettings(), config portal starts ok on 10.0.1.1.
When WiFi is connected using autoconnect and press a button which runs startConfigPortal() it goes to 192.168.4.1. Even adding setAPStaticIPConfig before startConfigPortal()

Settings in IDE

Module: Generic ESP8266 module
Flash size: 4M (3M SPIFFS)
all other parameters default
Additional libraries:
ESP8266mDNS.h
TimeLib.h
NtpClientLib.h
DNSServer.h
HLW8012.h

Do you have sketch ?
Is WM global or are you setting apconfig in loop where button is pressed?

cant reproduce, it has something to do with your other code, or the mode its in

wifi_softap_dhcps_stop failed
I have no idea why this would be failing, maybe conflict with starting mode, or is not switching ap correctly.

It could also be an open issue I have in esp with enableAP

you can maybe add a delay in

bool ESP8266WiFiAPClass::softAPConfig(IPAddress local_ip, IPAddress gateway, IPAddress subnet) {
    DEBUG_WIFI("[APConfig] local_ip: %s gateway: %s subnet: %s\n", local_ip.toString().c_str(), gateway.toString().c_str(), subnet.toString().c_str());
    if(!WiFi.enableAP(true)) {
        // enable AP failed
        DEBUG_WIFI("[APConfig] enableAP failed!\n");
        return false;
    }
delay(1000); // race condition delay workaround

I also wonder if swapping the order of these 2 would help

// wifimanager.cpp
  // setup optional soft AP static ip config
  if (_ap_static_ip) {
    DEBUG_WM(F("Custom AP IP/GW/Subnet:"));
    if(!WiFi.softAPConfig(_ap_static_ip, _ap_static_gw, _ap_static_sn)){
      DEBUG_WM(DEBUG_ERROR,"[ERROR] softAPConfig failed!");
    }
  }

  #ifdef ESP8266
    // @bug workaround for bug #4372 https://github.com/esp8266/Arduino/issues/4372
    if(!WiFi.enableAP(true)) {
      DEBUG_WM(DEBUG_ERROR,"[ERROR] enableAP failed!");
      return false;
    }
    delay(500); // workaround delay
  #endif

and place the enableap before the softAPConfig

<!-- gh-comment-id:418786980 --> @tablatronix commented on GitHub (Sep 5, 2018): I also wonder if swapping the order of these 2 would help ```C++ // wifimanager.cpp // setup optional soft AP static ip config if (_ap_static_ip) { DEBUG_WM(F("Custom AP IP/GW/Subnet:")); if(!WiFi.softAPConfig(_ap_static_ip, _ap_static_gw, _ap_static_sn)){ DEBUG_WM(DEBUG_ERROR,"[ERROR] softAPConfig failed!"); } } #ifdef ESP8266 // @bug workaround for bug #4372 https://github.com/esp8266/Arduino/issues/4372 if(!WiFi.enableAP(true)) { DEBUG_WM(DEBUG_ERROR,"[ERROR] enableAP failed!"); return false; } delay(500); // workaround delay #endif ``` and place the enableap before the softAPConfig

I moved the wifiManager.setAPCallback(); after startap, I think will break this implementation
It now fires after ap is started , so it can get ip and stuff

do we need a startapconfig callback, is there anything that needs to be done here that cannot be set via wm ahead of time ?

Where did we leave off here ? ughh

I think its safe to close, might need to reopen a new issue for more callbacks if needed
