Basic Infos

Hardware

WiFimanager Branch/Release:

  • Development

Esp8266/Esp32:

  • ESP8266

Hardware: ESP-12e, esp01, esp25

  • ESP01

1.8.0 version of https://github.com/platformio/platform-espressif8266

Description

Run WebPortal and ESP connects to router successful.
ESP connects to router after deep sleep.
Run WebPortal (see SSID name in field) and didn't select SSID, password fields. Change only custom parameters. Press OK.

Debug Messages

Source

I had a lot of additional code and little ESP code.

void loop() {
   
    if (setup) {   
        WiFiManager wm;
        wm.setConfigPortalTimeout(300);
        wm.setConnectTimeout(15);
        wm.startConfigPortal( AP_NAME );
    } 
    else {  
       WiFi.begin();  
       //do smth
    }
    ESP.deepSleep(0, RF_DEFAULT);
}

Additional news:

  1. branch: hotfix, development
    If I set this
        WiFi.persistent(false);  
        WiFi.disconnect(); 
        WiFi.mode(WIFI_AP);         
        WiFi.persistent(true);

before wm.startConfigPortal( AP_NAME ):
Run ESP startConfigPortal, refill saved SSID, password, push OK.
ESP doesn't connect to router, that has been already connected before.

  1. branch: development
    If router turn off ESP connecting failed after timeout correctly.

  2. branch: development
    Cyrillic labels shows nice in ConfigPortal.

Idea about Integration tests:

I see a lot of Issues with abnormal behaviour in different modes, routers and some other stuff...
Maybe it possible to create Python/Bash script and ESP test sketch to preserve regression bugs in depending libraries and helps users to check their routers & code?

I think, we can turn on wi-fi active point in linux PC by command line commands, we can talk with ESP by Serial and check it states.

What do you mean you need to refill, you mean it does not reconnect on save with ssid empty? I think this issue is confusing, I am not sure what you are inferring with the side notes also

If I don't write SSID when I open ConfigPortal, ESP doesn't connect. I think SSID&pwd are saved in memory and need not be filled every time when I open ConfigPortal...

If user should fill SSID every time in ConfigPortal, please don't show previous SSID name in the field.

@tablatronix it's easy to fill down saved SSID & password to the input web form:

  pitem = FPSTR(HTTP_FORM_WIFI);
  pitem.replace(FPSTR(T_v), WiFi_SSID());  //move T_v from placeholder to value
  pitem.replace("{pwd}", WiFi_psk());  //add value='{pwd}' to template

placeholder='' value='{v}'>
type='password' placeholder='' value='{pwd}'

Now you can run Captive Portal for custom parameters changes without refilling SSID & pwd.
I can make pull request if this way ok. I don't know why it wasn't done before.

If SSID and password saved in ESP, we should show this fact to the user. Not in placeholder.

If they are empty it skips saving, also sending the password back to the web is a security risk

Hm.. about security I haven't think. Okey, we can send dots to interface value attribute. After Saved we call smth like this:

  1. if (strlen(pwd) == strlen(WiFi_psk()) && pwd.replace('.','').empty()) {
    pwd = WiFi_psk();
    }

  2. or: type='password' placeholder='password hidden' - so user see, that password already saved in ESP.
    After click: if (pwd.empty()) { pwd = WiFi_psk(); }

#974

Are you talking to me? It already exists, just change the menu to show setup and it will automatically STOP using the WIFI page for params... This will probably be the default at some point, adding empty ssid checking was complex..

@tablatronix hm..

  1. To show dots on the page is good.
  2. I said, that previously saved password doesnt' work. In #974 you fill placeholder, not value. POST request parameter will be empty and ESP won't connect.

Now you should write down ssid & password every time you start ConfigPortal.

Ok, step by step.

  1. First run startConfigPortal

  2. Fill SSID, Password, click Save

  3. Connect OK. Turn off device.

  4. Second time run startConfigPortal

  5. I see SSID in placeholder, nothing in Password. Click Save.

  6. Connect FAILED. I see *WM: No ssid, skipping wifi

My device is autonomous, so I turn off power after startConfigPortal.
So, If I want to call startConfigPortal second time (after reboot) I should fill password.

p.s. Device connect to wi-fi successfully after reboot, here is no problem.

ok I see the problem

Saving Credentials
Trying to connect ESP to network.
If it fails reconnect to AP to try again

If // wm.setBreakAfterConfig(false); (default) and no wifi to save, the portal stays open.
The message above is wrong.

Ill make it a little better to understand.

If you want the portal to always close after save, use

wm.setBreakAfterConfig(true);

I know, that if connect failed (wrong password) it's also stays open - it's okey.

See this example:
https://github.com/tzapu/WiFiManager/blob/development/examples/ParamsChildClass/ParamsChildClass.ino it's close to my sketch, but I turn off power in the loop.

So, If you run startConfigPortal second time, you should refill password.
