Question: getting update progress

[ghost]

Hi guys!
How can I get the firmware upgrade progress?

ESP8285
1M/128K
80MHz

void updateESP() {
  flagUpdateESP = false;
  sendUART("SYS", "updateESP", "Start");            // Сообщаем о начале прошивки ESP
  if (_updateFW(true)) {                            // Обновляем FS
    saveConfig();                                   // Сохраняем текущие настройки в новую FS
    if (_updateFW(false)) {                         // Обновляем прошивку модуля
      sendUART("SYS", "updateESP", "End");          // Прошивка ESP завершена
    }
  }
}

bool _updateFW(bool updTarget) {
  HTTPClient httpClient;
  httpClient.useHTTP10(true);
  httpClient.setTimeout(5000);
  char url[65];
  sprintf(url, "http://%s/%s-%d-%s.bin", OTA_HOST, DEVICE_MODEL, latVer, updTarget ? "ffs" : "esp");
  httpClient.begin(url);
  if (httpClient.GET() != HTTP_CODE_OK) {
    sendUART("ER!", "updateESP", "Unable to Fetch");
    return false;
  }
  if (!Update.setMD5(updTarget ? ffsMD5 : espMD5)) {
    sendUART("ER!", "updateESP", "MD5");
    Update.printError(Serial);
    return false;
  }
  if (!Update.begin(httpClient.getSize(), updTarget ? U_SPIFFS : U_FLASH)) {
    sendUART("ER!", "updateESP", "Begin");
    Update.printError(Serial);
    return false;
  }
  if (!Update.writeStream(*httpClient.getStreamPtr())) {
    sendUART("ER!", "updateESP", "Write Stream");
    Update.printError(Serial);
    return false;
  }
  if (!Update.end()) {
    sendUART("ER!", "updateESP", "End");
    Update.printError(Serial);
    return false;
  }
  httpClient.end();
  return true;
}

The update is going well, but I want to know how much is completed.
Help.

@MCMeGa I believe the updated class has callbacks, and one is for progress. I haven't used them myself, but "use the source, Luke!".
Closing per issue policy doc.

It works, maybe someone will need it!
Updating the file system and sketch from the remote server with checking md5 and returning the progress in percent.

void updateESP() {
  sendWS(NULL, "infoMessage", "FFS Update...");
  if (_updateFW(true)) {
    delay(250);
    sendWS(NULL, "infoMessage", "ESP Update...");
    if (_updateFW(false)) {
      sendWS(NULL, "infoMessage", "All Updates Completed");
      delay(250);
    }
  }
}

bool _updateFW(bool updTarget) {
  udp.close();
  HTTPClient httpClient;
  httpClient.useHTTP10(true);
  httpClient.setTimeout(5000);
  char url[65];
  sprintf(url, "http://%s/%s-%d-%s.bin", OTA_HOST, DEVICE_MODEL, latVer, updTarget ? "ffs" : "esp");
  httpClient.begin(url);
  if (httpClient.GET() != HTTP_CODE_OK) {
    sendWS(NULL, "infoMessage", "Unable to fetch, please reboot the device and try again");
    return false;
  }
  int httpSize = httpClient.getSize();
  if (!Update.setMD5(updTarget ? ffsMD5 : espMD5)) {
    sendWS(NULL, "infoMessage", "Invalid MD5, please reboot the device and try again");
    return false;
  }
  if (!Update.begin(httpSize, updTarget ? U_SPIFFS : U_FLASH)) {
    sendWS(NULL, "infoMessage", "Incorrect startup conditions, please reboot the device and try again");
    return false;
  }
  uint8_t buff[1024] = { 0 };
  size_t sizePack;
  WiFiClient * stream = httpClient.getStreamPtr();
  while (httpClient.connected() && (httpSize > 0 || httpSize == -1)) {
    sizePack = stream->available();
    if (sizePack) {
      int c = stream->readBytes(buff, ((sizePack > sizeof(buff)) ? sizeof(buff) : sizePack));
      Update.write(buff, c);
      if (httpSize > 0)
        httpSize -= c;
    }
    if (progress != int(Update.progress() * 100 / httpClient.getSize())) {
      progress = int(Update.progress() * 100 / httpClient.getSize());
      updTarget ? sendWS(NULL, "updPrgFFS", String(progress)) : sendWS(NULL, "updPrgESP", String(progress));
    }
  }
  if (!Update.end()) {
    sendWS(NULL, "infoMessage", "Invalid completion conditions, please reboot the device and try again");
    return false;
  }
  httpClient.end();
  return true;
}

Its would be really great to have a callback function for the progress, instead of hacky workarounds :/
In my project, I really need to show the progress, but I can't get it working:

How can I get the progress working with my code?

void checkForUpdates() {
  display_text("Checking for updates");
  // display.drawProgressBar(4, 40, 120, 8, 10);
  // display.display();

  // String fwVersionURL = String(fwUrlBase)+"/"+String(DeviceName)+".version";

  Debug.println("[checkForUpdates]: Checking for firmware updates.");
  Debug.println("[checkForUpdates]: Firmware version URL: "+String(fwUrlBase));

  t_httpUpdate_return ret = ESPhttpUpdate.update(fwUrlBase, String(FW_VERSION));
  switch(ret) {
      case HTTP_UPDATE_FAILED:
          Debug.println("[checkForUpdates]: Update failed: "+String(ESPhttpUpdate.getLastErrorString()));
          break;
      case HTTP_UPDATE_NO_UPDATES:
          Debug.println("[checkForUpdates]: No Update needed");
          break;
      case HTTP_UPDATE_OK:
          Debug.println("[checkForUpdates]: Update ok."); // may not called we reboot the ESP
          break;
  }

Yes, I too would like to get progress when using ESPhttpUpdate.update(). Thanks!

I managed to get a progress bar working on httpupdate but not on this library. Please help us here.

Hi! I see this progress callback function is merged, but how to use it? Are there any examples?
EDIT: never mind, just found the example here: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266httpUpdate/examples/httpUpdate/httpUpdate.ino

@franzuu Thanks for the link, it was helpful.
