Description

I use your WifiManager to connect to my home Network. It works fine. But after i get some infos from the internet i disconnect the wifi in my Code. it should reconnect if i press a button. but if i do that, always the AP Config mode fires up and i get the error: [ERROR] wifi begin failed

Settings in IDE

Module: Wemos D1 & R2 mini

Additional libraries:

Sketch

I disconnect with this code:

WiFi.persistent(false);
WiFi.disconnect();
WiFi.persistent(true);

and i try to reconnect with this code:
wm.autoConnect("Clock_Config");

*WM: [0] [ERROR] wifi begin failed
hmm this is something in the esp lib failing

Can you try using wm.disconnect() instead ?

Thanks, something must be left hanging with the esp method. Glad it helped

I have a similar problem.

Here my code:

#include <WiFiManager.h> 
WiFiManager wm;
void setup() {
  Serial.begin(115200);
  startWiFi();
}
void loop() {
   delay(3000);
   Serial.println("Wifi Disconnect");
   wm.disconnect();
   delay(3000);
   int conn_result = WiFi.waitForConnectResult(10000);    
   Serial.print("Connection Result: ");
   Serial.println(conn_result);
}
// -------------------------------------------------------------------------
//                               startWiFi
// -------------------------------------------------------------------------
   //for reference:
    //typedef enum {
    //    WL_NO_SHIELD = 255,   // for compatibility with WiFi Shield library
    //    WL_IDLE_STATUS = 0,
    //    WL_NO_SSID_AVAIL = 1,
    //    WL_SCAN_COMPLETED = 2,
    //    WL_CONNECTED = 3,
    //    WL_CONNECT_FAILED = 4,
    //    WL_CONNECTION_LOST = 5,
    //    WL_DISCONNECTED = 6
    //} wl_status_t;
void startWiFi() {
    WiFi.mode(WIFI_STA); //  Station Mode 
    WiFi.setSleepMode(WIFI_NONE_SLEEP);
    Serial.println("");
    //wm.resetSettings(); //reset wifi settings
    Serial.print("WiFi saved?: ");
    Serial.println((String)wm.getWiFiIsSaved() ? "YES" : "NO");
    if (!wm.getWiFiIsSaved()) {
        Serial.println("Starte Konfigurationsportal!");
        if (!wm.startConfigPortal("MS_Clock_Config")) {
            Serial.println("failed to connect and hit timeout");
            delay(3000);
            ESP.reset();
            delay(5000);
        }
    }
    if (!WiFi.isConnected()) { // if not connected then connect
        Serial.println("SSID: " + WiFi.SSID());
        int conn_result = WiFi.waitForConnectResult(10000); // connect to wlan, try it max 10 Seconds
        Serial.print("conn_result: ");
        Serial.println(conn_result, DEC);
        if (conn_result == 1) {
            Serial.println("FEHLER: Wlan nicht erreichbar! SSID nicht gefunden.");
        }
        if (conn_result == -1) {
            Serial.println("FEHLER: Wlan nicht erreichbar! Timeout.");
        }
        if (conn_result != -1 && conn_result != 3 && conn_result != 1 ) {
            Serial.println("FEHLER: Wlan nicht erreichbar!");
        }
    }
    if (WiFi.isConnected()) {
        Serial.println("Wifi is connected!");
    }
    else {
        Serial.println("Wifi is not connected!");
    }
    Serial.println("");
}

Here is the Result:
WiFi saved?: YES
SSID: hotspot_test
conn_result: 3
Wifi is connected!

Wifi Disconnect
*WM: [1] Disconnecting
*WM: [3] WiFi station disconnect
Connection Result: 0
Wifi Disconnect
*WM: [2] Disconnecting: Not connected
Connection Result: 0
Wifi Disconnect
*WM: [2] Disconnecting: Not connected
Connection Result: 0

The first connect works fine conn_result: 3
Then i disconnect and after a delay i try to connect with the same method as before and the connect result is always 0
with WiFi.disconnect() is the same problem.

Why? what is wrong?
