I use the basic ota example.
I can upload the sketch without problems. i must enter the password and it works.
But if i want to upload "esp8266 Sketch Data Upload" (in the arduino ide Tools Menu) then i get these Error:

Code: Select all

Authenticating...FAIL

14:24:44 [ERROR]: Authentication Failed

SPIFFS Upload failed!

What is wrong and how can i fix this?

Can't help you with Arduino IDE since I'm not using it, but I can give you a workaround:

Code: Select all

void downloadFile(String url, String destination){
   HTTPClient http;
   http.begin(url);
   int httpCode = http.GET();
   if(httpCode > 0) {
      File ff = SPIFFS.open(destination, "w");
      int len = http.getSize();
      uint8_t buff[128] = { 0 };
      WiFiClient * stream = http.getStreamPtr();
      while(http.connected() && (len > 0 || len == -1)) {
         size_t size = stream->available();
         if(size) {
            int c = stream->readBytes(buff, ((size > sizeof(buff)) ? sizeof(buff) : size));
            ff.write(buff, c);
         }
      }
      ff.close();
   }
}

Now. You set up a basic web server on your computer, put the files on it and you can download them to SPIFFS using a piece of code like the one above. Usually makes more sense than flashing entire image anyways. It's faster too.

The sketch Data Upload tool does work over OTA, but only when no password is set. See topic https://github.com/esp8266/arduino-esp8266fs-plugin/releases/tag/0.2.0.

So it is possible to upload data. You can first upload the sketch with no OTA-password set. Upload the data. Then upload the sketch with OTA-password.

Another option is to use esp8266FTPServer in your sketch. See https://github.com/nailbuster/esp8266FTPServer
