- Mon Mar 21, 2016 6:22 am #43697 Hi, I get the following crash when I try to update the node in my sketch, any idea of the cause? If a make a standalone sketch just to test the upgrade it (sort of) works, it doesn't crash and it works not immediatly after I program it to the node, but works after programming and reseting the node. I'm using the NodeMCU 0.9 configuration, with a custom board with an ESP12 module. Could it be a RAM issue, since it works with a simple sketch and not with this sketch?

Thanks in advance!

Fernando

Code:

Code: Select all  Serial.println("\nChecking if there is an updated firmware");
  t_httpUpdate_return ret = ESPhttpUpdate.update(upgradeFile);
  Serial.print("Update: ");
  Serial.println(ret);
  switch(ret) {
       case HTTP_UPDATE_FAILED:
          Serial.printf("HTTP_UPDATE_FAILD Error (%d): %s", ESPhttpUpdate.getLastError(), ESPhttpUpdate.getLastErrorString().c_str());
          break;

      case HTTP_UPDATE_NO_UPDATES:
          Serial.println("HTTP_UPDATE_NO_UPDATES");
          break;

      case HTTP_UPDATE_OK:
          Serial.println("HTTP_UPDATE_OK");
          break;
  }


Result:

- Tue Mar 22, 2016 6:12 am #43775 Answering to my question, might be useful to others, if I move the update code to the start of the sketch it seems to work, so it seems that it is a RAM issue, the ESPhttpUpdate class might need some memory error handling in order to avoid the system crash without any additional information. Currently I am calling it after initializing another class that uses some 'large' RAM buffers, so it might not leave enough RAM for the ESPhttpUpdate.

Best regards

Fernando

- Fri Sep 09, 2016 6:24 am #54734 Hello Fernando,

Thanks for the post.

Thanks for providing the "ESP8266 WeatherStation Getting started" book.

At this moment I am engaged in developing the ESP8266 module which measures temperature and humidity.

Concerning Over The Air (OTA) update , I need to do it using HTTP Server.

But I cannot be able to find much resources in detailed on the internet.

Could you help me regarding this?
