Description

As the title says, when I call getWiFiIsSaved() it returns true if I don’t call resetSettings() before it after startup/deep sleep. If I reset the settings on the initial startup, the method works as expected, returning false if the AP is exited without configuring WiFi settings. On subsequent startups, however, it returns true if the settings are not reset explicitly.

I would expect it to still return false since no settings have been saved.

Note: Even without the deep sleep, as long as I don’t call resetSettings(), getWiFiIsSaved() returns true.

Sketch

#include <WiFiManager.h>

#define uS_TO_S_FACTOR 1000000ULL

WiFiManager wm;

void setup() {
  Serial.begin(115200);
  // put your setup code here, to run once:

  if(esp_sleep_get_wakeup_cause() == 0) {
    wm.resetSettings();
  }
  Serial.println("WiFi saved? " + String(wm.getWiFiIsSaved() ? "YES" : "NO"));

  if(wm.autoConnect("AutoConnectAP","password")) {
    Serial.println("Failed to connect");
    // ESP.restart();
  } else {
    //if you get here you have connected to the WiFi    
    Serial.println("connected...yeey :)");
  }
  
  Serial.println("WiFi saved? " + String(wm.getWiFiIsSaved() ? "YES" : "NO"));

  uint8_t sleepSeconds = 5;
  esp_sleep_enable_timer_wakeup(sleepSeconds * uS_TO_S_FACTOR);
  Serial.println("Sleeping for " + String(sleepSeconds) + " seconds...");
  esp_deep_sleep_start();
}

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

}
