ESPAsyncWiFiManager Unable to access Captive Portal

trafficstars

I have hard time setting up this library. I'm using Wemos D1 mini and PlatformIO as IDE.

My code is very simple (based on one of Your examples):

#include <FS.h>                   //this needs to be first, or it all crashes and burns...

#if defined(ESP8266)
#include <ESP8266WiFi.h>          //https://github.com/esp8266/Arduino
#else
#include <WiFi.h>
#endif

//needed for library
#include <ESPAsyncWebServer.h>
#include <ESPAsyncWiFiManager.h>         //https://github.com/tzapu/WiFiManager

#include "config.h"

//////////////////////////variables//////////////////////////
AsyncWebSocket ws("/ws");
AsyncWebServer server(80);
DNSServer dns;

///////////////////////////////////////////////////////////////////////////

void configModeCallback(AsyncWiFiManager *myWiFiManager)
{
    Serial.println("Entered config mode");
    Serial.println(WiFi.softAPIP());

    Serial.println(myWiFiManager->getConfigPortalSSID());
}

void setup()
{
    Serial.begin(115200);
    Serial.setDebugOutput(true);

    // Wait for connection
    AsyncWiFiManager wifiManager(&server, &dns);

    wifiManager.setAPCallback(configModeCallback);
    if (!wifiManager.autoConnect("TestAP", "password"))
    {
        Serial.println("failed to connect, we should reset as see if it connects");
        delay(30000);
        ESP.reset();
        delay(5000);
    }

    //if you get here you have connected to the WiFi
    Serial.println("connected...yeey :)");
    Serial.println("local ip");
    Serial.println(WiFi.localIP());

    server.on("/", HTTP_GET, [](AsyncWebServerRequest *request) {
        request->send(200, "text/plain", "Hello World");
    });

    server.on("/reset", HTTP_GET, [](AsyncWebServerRequest *request) {
        ESP.restart();
    });

    server.onNotFound([](AsyncWebServerRequest *request) {
        request->send(404);
    });

    // Start the webserver
    //
    server.begin();
    Serial.println("Webserver started ");

    pinMode(BUILTIN_LED, OUTPUT); // initialize onboard LED as output

    Serial.println("Led setup");
}

int led_1_blink_time = 200;
long led_1_last_blink;

void loop()
{
    if ((millis() - led_1_last_blink) >= led_1_blink_time)
    {
        if (digitalRead(BUILTIN_LED) == HIGH)
        {
            digitalWrite(BUILTIN_LED, LOW);
        }
        else
        {
            digitalWrite(BUILTIN_LED, HIGH);
        }
        led_1_last_blink = millis();
    }
}

When I upload this code to my board I can see this output in Serial Port monitor:

I'm just getting started with Wemos and Arduino stuff, so I don't know how should I interpret that output. Any hints are more than welcome!

I installed PlatformIO and ran your code.. I can't get it to work either. I will try to work on it later.

@alanswx I'm installing Arduino IDE right now and I will try Your lib there. I have latest versions of libraries in PlatformIO. I'm using Espressif 8266 1.7.3 as platform.

If You find the reason why this might not work I'll be more than grateful.

I've noticed that similar error were described here: https://github.com/esp8266/Arduino/issues/1847 fix was to add couple of delay(0)

There is something indeterminate about the code now. If you figure out a fix, please add a comment, and/or a pull request.
