Description

Problem description
In case of WIFI router down and leater restarted WiFi.SSID() will be empty and WM goes in AP mode.

*WM: [1] AutoConnect
*WM: [2] Connecting as wifi client...
*WM: [1] STA static IP:
*WM: [2] setSTAConfig static ip not set
*WM: [3] WIFI station disconnect
*WM: [1] No saved credentials, skipping wifi ??????
*WM: [2] Connection result: WL_NO_SSID_AVAIL
*WM: [3] lastconxresult: WL_NO_SSID_AVAIL
*WM: [1] AutoConnect: FAILED
*WM: [3] WIFI station disconnect
*WM: [3] WiFi station enable
*WM: [2] Disabling STA
*WM: [2] Enabling AP
*WM: [1] StartAP with SSID: ASlabs
*WM: [2] AP has anonymous access!
*WM: [1] AP IP address: 192.168.4.1

Probably is ESP8266 WiFi issue

I simply SOLVED saving _MYssid and _MYpass end try a new connection.
Function uint8_t WiFiManager::connectWifi(String ssid, String pass)

become:

// @todo refactor this up into seperate functions
// one for connecting to flash , one for new client
// clean up, flow is convoluted, and causes bugs
uint8_t WiFiManager::connectWifi(String ssid, String pass) {
DEBUG_WM(DEBUG_VERBOSE,F("Connecting as wifi client..."));

uint8_t connRes = (uint8_t)WL_NO_SSID_AVAIL;

setSTAConfig();
//@todo catch failures in set_config

// make sure sta is on before begin so it does not call enablesta->mode while persistent is ON ( which would save WM AP state to eeprom !)
if(_cleanConnect) WiFi_Disconnect(); // disconnect before begin, in case anything is hung, this causes a 2 seconds delay for connect
// @todo find out what status is when this is needed, can we detect it and handle it, say in between states or idle_status

// if ssid argument provided connect to that
if (ssid != "") {
wifiConnectNew(ssid,pass);
if(_saveTimeout > 0){
connRes = waitForConnectResult(_saveTimeout); // use default save timeout for saves to prevent bugs in esp->waitforconnectresult loop
}
else {
connRes = waitForConnectResult(0);
}
}
else {
// connect using saved ssid if there is one
if (WiFi_hasAutoConnect()) {
wifiConnectDefault();
connRes = waitForConnectResult();
}
else {
DEBUG_WM(F("No saved credentials, skipping wifi"));
DEBUG_WM(connRes);
}
}

//***** ASLABSIT ******//
// Try with my saved credential

if (connRes == WL_NO_SSID_AVAIL)
{
DEBUG_WM(F("Using MY CONFIG parameter"));

ETS_UART_INTR_DISABLE();
wifi_station_disconnect();
ETS_UART_INTR_ENABLE();

WiFi.begin(_MYssid, _MYpass);
delay(100);
connRes = waitForConnectResult();
DEBUG_WM("MY Connection result: ");
DEBUG_WM(connRes);

}
//***** ASLABSIT ******//

....

_MYssid, _MYpass were previosly saved.

Probably there will be a better way to do that ;-) ....this is my workaround.

Regards.

If your credentials are not being saved you have a memory problem, erase your flash
this is completely unnecessary as it is already the supposed to be the default behavior.
