What do you mean if you run webportal a second time ? ONdemand ? Or after a reset?

I might have to fix this, it does nothing unless you set wifiManager.setBreakAfterConfig(true);
Probably need to add a param callback, else this really cannot work properly the way it has always been written.

Yes, second time filled wi-fi doesnt connect.
you need to fill wrong password, wait error in log, change to correct password to connect.

Yes,if fields are empty no wifi connection.

ok well you should be able to just leave it empty now at least and it will ignore it

There is a problem reconnecting once mode changes, and the only fix was to add a disconnect, I will check the other issue and see what the problem is, I thought there was a workaround in hotfixes for that already.

I imagine to build ESP test board:
3 NodeMCU:

  1. Active Point, controled by script
  2. WIFI client - http requests, controled by script
  3. Target - with testing firmware. Flashing, reseting by script

We will be able to run scripts for different tasks

Try to test connect 2nd time: Failed.
ESP-12
Branch: hotfix

I found a HACK:

in ESP8266WiFiSTA.cpp

wl_status_t ESP8266WiFiSTAClass::begin(const char* ssid, const char *passphrase, int32_t channel, const uint8_t* bssid, bool connect) {

/*
    if(sta_config_equal(conf_compare, conf)) {
        DEBUGV("sta config unchanged");
    }
    else */ 
}
  1. run as client with saved ssid, pass
  2. run ConfigPortal + curl "http://192.168.4.1/wifisave?s=don&p=x"
  3. run ConfigPortal + curl "http://192.168.4.1/wifisave?s=don&p=x" SUCCESS!!!

@dontsovcmc commented on GitHub (Apr 1, 2019):

@tablatronix look, I think, I found a bug in ESP8266WiFiSTA!

Wow.. I debugging ESP8266WiFiSTA.cpp, so this is not your bugs..

I try to understand: is configurations are same? I print structures as hex and see, that

    Serial.println("conf_compare:");
    char *p = (char*)(void*)&conf_compare;
    char b[5] = { 0, 0, 0, 0, 0};
    for (unsigned int i = 0; i < sizeof(struct station_config); i++) {
        snprintf(b, 3, "%02X", *p);
        p++;
        Serial.print(b);
    }

    Serial.println();
    Serial.println("conf:");
    p = (char*)(void*)&conf;
    for (unsigned int i = 0; i < sizeof(struct station_config); i++) {
        snprintf(b, 3, "%02X", *p);
        p++;
        Serial.print(b);
    }
  1. conf_compare & conf have a lot of garbage cause doesn't setmem 0 when creating.
  2. the function sta_config_equal doesn't works good, because there are no some fields of station_config!!

Look! Is the same SSID & password Wi-Fi structures are same?

conf_compare:
646F6E0000000000000000000000000000000000000000000000000000000000

00000000000000000810000000200000001000000

I make:

  1. add all fields to sta_config_equal
  2. memset 0 for all struct station_config
    It works!

<!-- gh-comment-id:478411950 --> @dontsovcmc commented on GitHub (Apr 1, 2019): @tablatronix look, I think, I found a bug in ESP8266WiFiSTA! Wow.. I debugging ESP8266WiFiSTA.cpp, so this is not your bugs.. I try to understand: is configurations are same? I print structures as hex and see, that ``` Serial.println("conf_compare:"); char *p = (char*)(void*)&conf_compare; char b[5] = { 0, 0, 0, 0, 0}; for (unsigned int i = 0; i < sizeof(struct station_config); i++) { snprintf(b, 3, "%02X", *p); p++; Serial.print(b); } Serial.println(); Serial.println("conf:"); p = (char*)(void*)&conf; for (unsigned int i = 0; i < sizeof(struct station_config); i++) { snprintf(b, 3, "%02X", *p); p++; Serial.print(b); } ``` 1. conf_compare & conf have a lot of garbage cause doesn't `setmem 0` when creating. 2. the function sta_config_equal doesn't works good, because there are no some fields of station_config!! Look! Is the same SSID & password Wi-Fi structures are same? ``` conf_compare: 646F6E0000000000000000000000000000000000000000000000000000000000 3232327177654153445A58430000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 000107BEF5C074400000000000000000001000000 conf: 646F6E0000000000000000000000000000000000000000000000000000000000 3232327177654153445A58430000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000810000000200000001000000 ``` I make: 1. add all fields to sta_config_equal 2. memset 0 for all struct station_config It works!
