Getting exception(29) sometimes when saving an image from the web using Web_Fetch functions #21

Closed bmarcu13 closed 3 years ago

bmarcu13 commented 3 years ago

Sometimes when I try to download multiple images my ESP8266 resets itself (before trying to download one of the images) giving this error:

22:31:49.969 -> Exception (29):

Here is my code:

void loop(void) {

  Firebase.get(dbGifFrames, "/gif_paths/1614716950720/frames");
  dbGifFrames.pauseFirebase(true);
  gifFrames = dbGifFrames.intData();
  Serial.println(gifFrames);
  for (int i = 1; i <= gifFrames; i++) {
    yield();
    String currentFramePath = "/gif_paths/1614716950720/";
    currentFramePath.concat(i);
    Firebase.getString(currentFrameLink, currentFramePath);
    gifPath = currentFrameLink.stringData();
    Serial.println(gifPath);
    String localPath = "/jp";
    localPath.concat(i);
    localPath.concat(".jpg");
    currentFrameLink.pauseFirebase(true);
    bool loaded_ok = getFile(gifPath, localPath);
    currentFrameLink.pauseFirebase(false);
  }
  while (true) {
    for (int i = 1; i <= gifFrames; i++) {
      Serial.print(i);
      Serial.print(" ");
      String pathToRender = "/jp";
      pathToRender.concat(i);
      pathToRender.concat(".jpg");
      TJpgDec.drawFsJpg(0, 0, pathToRender);
      delay(50);
    } 
    Serial.println();
  }
  delay(5000);
}

I did some research and I found this probable cause (the first answer): Stack Overflow The download library probably tries to save the image in a protected memory area. I still don't know how I can work around this though.

Bodmer commented 3 years ago

The library itself is a decoder and has no web/network download capability. Typically images are downloaded in small chunks and saved to SPIFFS or LITTLEFS, before decoding as the ESP8266 has limited RAM.

I assume this has been resolved - closing.
