Problem with Nodemcu storage

[SRJ]

Hello experts,

I am working on a project having ESPAsyncWebserver & uploaded my files in SPIFFS & serving that files to the connected devices using wifi.

The issue here is the ESP is forgetting SPIFFS files & PREFERENCES data after power cut.

I had loaded SPIFFS files using ESP SKETCH data upload tool in Arduino IDE 1.x

Why this might happening?

My compiled binary size is approx 400 kb & SPIFFS Data is not more than 8 kb.

My tools settings:

My code:

type or paste code here#include <ESP8266WiFi.h>
#include "ESPAsyncWebServer.h"
#include "FS.h"
#include <DNSServer.h>
#include <Preferences.h>
#include <RTClib.h>
#include <Wire.h>
#include "var.h"
#include <ArduinoJson.h

RTC_DS1307 rtc;
int relayState = 0;
DNSServer dnsServer;
AsyncWebServer server(80);
Preferences preferences;
DateTime now;

// Replace with your network credentials
const char *ssid = "TimerX";
const char *password = "Password";


void setup() {
  Serial.begin(115200);
  if (!rtc.begin()) {
    Serial.println("Couldn't find RTC");
    Serial.flush();
    while (1) delay(10);
  }
  if (!SPIFFS.begin()) {
    Serial.println("An Error has occurred while mounting SPIFFS");
    return;
  }





  IPAddress ip(192, 168, 0, 8);
  IPAddress gateway(192, 168, 0, 1);
  IPAddress subnet(255, 255, 255, 0);

  WiFi.softAPConfig(ip, gateway, subnet);
  WiFi.mode(WIFI_AP);
  if (!WiFi.softAP(ssid, password)) {
    Serial.println("Failed to set up SoftAP");
    return;
  }

  delay(100);
  Serial.println("Access Point IP address: " + WiFi.softAPIP().toString());


  // Start DNS server
  dnsServer.start(53, "*", WiFi.softAPIP());


  server.onNotFound([](AsyncWebServerRequest *request) {
    String dta = HmepgHTML(String(now.hour()), String(now.minute()), String(now.second()), String(now.dayOfTheWeek()), String(now.day()), String(now.month()), String(now.year()), relayState);
    request->send(200, "text/html", dta);
  });

  // Route for Home page
  server.on("/", HTTP_GET, [](AsyncWebServerRequest *request) {
    //HmepgHTML(Hr, Min, Second, Day, Date, Month, Year, Relay State)
    String dta = HmepgHTML(String(now.hour()), String(now.minute()), String(now.second()), String(now.dayOfTheWeek()), String(now.day()), String(now.month()), String(now.year()), relayState);

  });

  // Route for Home page CSS
  server.on("/hmStyle.css", HTTP_GET, [](AsyncWebServerRequest *request) {
    Serial.println("This ran!!!!!!!!!!!!!!!!!!!!!!!");
    request->send(SPIFFS, "/style.css", "text/css");
    //request->send(200, "text/css", "dta0");
  });

  // Route for Home page JS
  server.on("/HMscript.js", HTTP_GET, [](AsyncWebServerRequest *request) {
    String dta0 = HmJS(getRelStBtnPref());
    request->send(200, "application/javascript", dta0);
  });


  // Route for Sys page
  server.on("/Sys", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(SPIFFS, "/Sys/index.html");
  });

  // Route for Sys page CSS
  server.on("/SysStyle.css", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(SPIFFS, "/Sys/style.css");
  });

  // Route for AddEve page
  server.on("/AddEve", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(SPIFFS, "/AddEve/index.html");
  });

  // Route for AddEve page CSS
  server.on("/AddEveStyle.css", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(SPIFFS, "/AddEve/style.css");
  });

  // Route for ManEve page
  server.on("/manEve", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(SPIFFS, "/ManEvn/manEve.html");
  });

  // Route for ManEve page CSS
  server.on("/manEveCss.css", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(SPIFFS, "/ManEvn/manEveCss.css");
  });



  server.on("/dtTmUpdateRTC", HTTP_GET, dtTmUpdateRTCHandler);

  server.on("/RelStBtn", HTTP_GET, RelStBtnHandler);

  server.on("/ESecHmDta", HTTP_GET, ESecHmDtaHandler);

  server.on("/RelStBtn", HTTP_GET, RelStBtnHandler);


  // Start server
  server.begin();
}

void loop() {
  now = rtc.now();
  dnsServer.processNextRequest();
}

void RelStBtnHandler(AsyncWebServerRequest *request) {
  // Get formatted time from request body
  String Btn = request->arg("Option");
  Serial.println("Button Option: " + Btn);

  // Send response 
  request->send(200, "text/plain", "");

  preferences.begin("Events", false);
  preferences.putString("SelBtnHTML", Btn);

  String tester = preferences.getString("SelBtnHTML", "na");
  Serial.println("Button Value set to: " + tester);

  preferences.end();
}


String getRelStBtnPref() {

  preferences.begin("Events", false);
  String tester = preferences.getString("SelBtnHTML", "0");
  Serial.println("Button Value readed as: " + tester);

  preferences.end();

  return tester;
}

Why it is happening?

Thanks

Your return in setup() will immediately go to loop(). Is this what you really want to happen?

It is when the SPIFFS or WIFI begin is failed....

I don't think it matters...
