title: How to convert .ino file into .bin file with "sketch + WiFi settings" from arduinoIDE to upload in S3 ESP8266 by "ESP8266 download tool"?
body: <p>I want to flash S3 ESP8266 module by "ESP8266 download tool". In arduinoIDE, when my setUp is like, tools->Erase Flash: <strong>only sketch</strong>. I can easily convert the blink.ino code into .bin and can flash it to my S3 ESP8266 module via "ESP8266 download tool", and can really see it's BuiltIn led blinking. </p>
  
  <p>But, when my setUp is like, tools->Erase Flash: <strong>sketch+WiFi settings</strong>. I can convert the blink.ino into .bin and can flash it to my S3 ESP8266 module via "ESP8266 download tool". But unfortunately it doesn't blink. My .ino code is simple.</p>
  
  <pre><code>void setup() {
    pinMode(4, OUTPUT);
  }
  
  void loop() {
    digitalWrite(4, HIGH);
    delay(1000); 
    digitalWrite(4, LOW);
    delay(1000);
  }
  </code></pre>
  
  <p>Options selected in ArduinoIDE's Tools,</p>
  
  <p><strong>Board : NodeMCU 1.0(ESP-12E Module)</strong></p>
  
  <p><strong>Flash Size : "4M (No SPIFFS)"</strong></p>
  
  <p>I think this issue is because of "build options" changes, but I don't know about it's solution. </p>
  
  <p>Is there anyThing that I am missing out ? Please help.</p>
