Description

basic example does not create the AP

using example skrtch (simple) for the first time (nothing stored on FS, no wifi data at all:
this is what I get on serial monitor
*WM:
*WM: AutoConnect
*WM: Connecting as wifi client...
W (253) wifi:Haven't to connect to a suitable AP now!
*WM: Using last saved values, should be faster
*WM: Connection result:
*WM: 3
*WM: IP Address:
*WM: 192.168.1.7
connected...yeey :)

`#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager

void setup() {
    WiFi.mode(WIFI_STA); // explicitly set mode, esp defaults to STA+AP

    // put your setup code here, to run once:
    Serial.begin(115200);
    
    // WiFi.mode(WiFi_STA); // it is a good practice to make sure your code sets wifi mode how you want it.

    //WiFiManager, Local intialization. Once its business is done, there is no need to keep it around
    WiFiManager wm;

    //reset settings - wipe credentials for testing
    //wm.resetSettings();

    // Automatically connect using saved credentials,
    // if connection fails, it starts an access point with the specified name ( "AutoConnectAP"),
    // if empty will auto generate SSID, if password is blank it will be anonymous AP (wm.autoConnect())
    // then goes into a blocking loop awaiting configuration and will return success result

    bool res;
    // res = wm.autoConnect(); // auto generated AP name from chipid
    // res = wm.autoConnect("AutoConnectAP"); // anonymous ap
    res = wm.autoConnect("AutoConnectAP","12345678"); // password protected ap

    if(!res) {
        Serial.println("Failed to connect");
        // ESP.restart();
    } 
    else {
        //if you get here you have connected to the WiFi    
        Serial.println("connected...yeey :)");
    }

}

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

That is not development the logs do not have log levels shown

ohh ok, I think that I installed the lib from Arduino IDE, that's what you mean?

Do I need to install the lib from the repository and then do all my tests?

If you can , there has been some updates. If not I should be posting a beta soon to arduino

I have tried below code from ESP32 Arduino boards manager v1.0.6 library. I found that similar problem that password protected AP will disappear to become an OPEN softAP after reset. It will happen if softAP restarted, even reburn program (no change flash setting area).

It is working fine if using ESP32 Arduino boards manager v1.0.4 library.
Any guys know what is it going on?
