HttpUpdate Example - HTTP_UPDATE_FAILD Error (-104): Wrong HTTP code

[Zyxmn]

I have tried to implement the HttpUpdate Example albeit it with a few changes. Here is my sketch:

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
/**

• httpUpdate.ino

• Created on: 27.11.2015

*/

include "Arduino.h"

include "ESP8266WiFi.h"

include "ESP8266httpUpdate.h"

const char* ssid = "ssid";
const char* password = "password";

void setup()
{
// put your setup code here, to run once:
Serial.begin(115200);
delay(100);

// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print(".");
}

Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
delay(500);

}

void loop()
{

    t_httpUpdate_return ret = ESPhttpUpdate.update("https://rawgit.com/Zyxmn/esp8266_BlinkyBin/master/Blinky.cpp.bin");

    delay(500);
    switch(ret) {
        case HTTP_UPDATE_FAILED:
            Serial.printf("HTTP_UPDATE_FAILD Error (%d): %s", ESPhttpUpdate.getLastError(), ESPhttpUpdate.getLastErrorString().c_str());
            Serial.println();
            Serial.println();
            Serial.println();
            break;

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

        case HTTP_UPDATE_OK:

}

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

I get the wrong http code error as mentioned in the title, I tried looking online but could not find anything useful. I was wondering if anyone can help me figure out how to resolve it.

Thanks a lot in advance fellas! Appreciate the help.

[igrr]

Which version of ESP8266 Arduino core are you using?

[Zyxmn]

The Adafruit Huzzah Board. The sketch has the libraries not showing;

These are the ones I use. I completely replaced the setup section of the example. To the one shown above.
#include Arduino.h
#include ESP8266WiFi.h
#include ESP8266HTTPClient.h
#include ESP8266httpUpdate.h

[igrr]

I mean, which version of software did you install? 2.0.0, 2.1.0, 2.2.0, 2.3.0-rc1, etc?

[Zyxmn]

Oh yeah sorry, its 2.2.0 .

[igrr]

Could you please try running the same with 2.3.0-rc1? There were some issues with HTTPClient library which were fixed in 2.3.0-rc1.

Edit: this version is available at http://arduino.esp8266.com/staging/package_esp8266com_index.json

[Zyxmn]

Installed the 2.3.0-rc1 , the code wont compile now . says

Board huzzah (platform esp8266, package esp8266) is unknown

Error compiling for board Adafruit HUZZAH ESP8266.

[igrr]

Did you remove 2.2.0 before installing 2.3.0-rc1?
If not, you may need to close the IDE and remove the old package.
On Windows, it is under Users\[username]\AppData\Roaming\Arduino15\packages\esp8266\hardware.
On Mac, /Users/$USER/Library/Arduino15/packages/esp8266/hardware.
See #1514, #1387.

[Zyxmn]

I did not remove the 2.2.0 before installing 2.3.0-rc1 . I manually deleted the 2.2.0 folder and installed the 2.3.0-rc1 like you said. The code compiles fine now.

The new HTTP error it shows now is :
HTTP_UPDATE_FAILED Error (-1): HTTP error: connection refused

[igrr]

Which is probably the correct behaviour now, because you are loading HTTPS URL without specifying certificate fingerprint. Could you try the same, replacing https with http in your binary URL?

[Zyxmn]

Tried the http version, the error is back to
HTTP_UPDATE_FAILED Error (-104): Wrong HTTP code

[igrr]

Your server sends HTTP code 301, "Moved permanently". ESP8266HTTPUpdate library doesn't support HTTP redirects at this point. It expects an URL which points directly to the binary.

[Zyxmn]

Thanks for that! Do you have any suggestions on servers I could use to get a direct link to the bin file?

[igrr]

Well using the URL from Location header above (https://raw.githubusercontent.com/Zyxmn/esp8266_BlinkyBin/master/Blinky.cpp.bin) worked for me.

[Zyxmn]

Could you please post the sketch you've used ? I have tried both the http and https URLS, and it still does not seem to be working for me.

HTTPS : gives the connection refused error
HTTP : gives the wrong http code error.

I even tried the default httpServer example, changing only the ssid password and the url . The results are the same.

[igrr]

Sketch was:

#include <Arduino.h>
#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include <ESP8266httpUpdate.h>

void setup() {
  Serial.begin(115200);
  Serial.setDebugOutput(true);
  Serial.println();

  WiFi.begin("testbox1", "testbox123");
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
  }
  Serial.println("Connected, updating");
  delay(1000);

  t_httpUpdate_return ret = ESPhttpUpdate.update("https://raw.githubusercontent.com/Zyxmn/esp8266_BlinkyBin/master/Blinky.cpp.bin", "", "21 99 13 84 63 72 17 13 B9 ED 0E 8F 00 A5 9B 73 0D D0 56 58");
}
void loop() {
}

Don't forget to power cycle the ESP after uploading this sketch, otherwise it will fail to update.

Thanks for the help @igrr !

Edit: After the OTA , the esp seems to require a manual reset every single time. This is what I received on my serial monitor using your sketch.

wdt reset

The system hangs after printing this out . A manual reset after this seems to run the new sketch . The serial monitor output is different to what you have posted for the same sketch. Like , some lines are missing and the reset cause seems to be different.

[igrr]

ESP requires manual reset after UART upload, but not after OTA upload.

Your boot mode (1,6) indicates that either you didn't reset ESP after UART upload, or GPIO0 was low at the time when it got reset after OTA.

[Zyxmn]

Not Resetting after UART upload was the reason. OTA works perfectly now. Cheers!

Can anyone help me with this issue...

I ahve hosted the bin file on Microsft IIS server at this location http://192.168.0.5:912/blinkredLedFast.bin.

If I try to access this link from browser I do get the download option. However if I use it in the code I get error as

HTTP_UPDATE_FAILD Error (-1): HTTP error: connection refused

I tried replacing the below code

t_httpUpdate_return ret = ESPhttpUpdate.update("http://192.168.0.5:912/blinkredLedFast.bin","80");

with
t_httpUpdate_return ret = ESPhttpUpdate.update("https://raw.githubusercontent.com/Zyxmn/esp8266_BlinkyBin/master/Blinky.cpp.bin", "", "21 99 13 84 63 72 17 13 B9 ED 0E 8F 00 A5 9B 73 0D D0 56 58");

and bin files get downloaded successfully. in to my Adafruit huzzah feather.

[kenpeter]

@igrr

ESP8266HTTPUpdate library doesn't support HTTP redirects at this point. It expects an URL which points directly to the binary.

There is a section called "Advanced updater" in https://esp8266.github.io/Arduino/versions/2.0.0/doc/ota_updates/ota_updates.html

Also in .arduino15/packages/esp8266/hardware/esp8266/2.3.0/doc/ota_updates/readme.md, line 342

It seems I can create a php script, then when hit this script, firmware will be downloaded, no need to hit the direct bin file in server. Am I correct?

Because I have a URL in laravel 5, which allows the firmware to be download dynamically. Currently, I am not able to make it working. In your comment above, esp update only allows direct hit to the bin file. Are you able to clarify?

[igrr]

Sorry, i'm not familiar with php and laravel. Currently HTTP response has to contain the actual binary, not a redirect to another URL. I.e. response code has to be 20x and with binary file in the body of response.

[kenpeter]

Hi,

This the url: https://toothfi.com/device/device/wifi_gateway/set_me_up/prod/get_firmware

1. I test this: curl -v https://toothfi.com/device/device/wifi_gateway/set_me_up/prod/get_firmware > out.txt
   HTTP/1.1 200 OK and out.txt is the binary file.
2. Try the code below, error: HTTP_UPDATE_FAILD Error (-1): HTTP error: connection refused

#include <Arduino.h>
#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include <ESP8266httpUpdate.h>

void setup() {
  Serial.begin(115200);
  Serial.setDebugOutput(true);
  Serial.println();

  WiFi.begin("xyz", "xyz");
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
  }
  Serial.println("Connected, updating");
  delay(1000);

  t_httpUpdate_return ret = ESPhttpUpdate.update("https://toothfi.com/device/device/wifi_gateway/set_me_up/prod/get_firmware");

  Serial.println(F("\n---- ota update done ----\n"));
  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(F("HTTP_UPDATE_NO_UPDATES"));
      break;
    case HTTP_UPDATE_OK:
      Serial.println(F("HTTP_UPDATE_OK"));
      break;
    default:
        Serial.printf("Unexpected response code %d from ESPhttpUpdate.update\n",(int)ret);
        break;

  }
}
void loop() {
}

3.The header I am using

// https://stackoverflow.com/questions/4345322/how-can-i-allow-a-user-to-download-a-file-which-is-stored-outside-of-the-webroot
  private function get_firmware_download($file) {

      header('Content-Disposition: attachment; filename='.basename($file));
      header('Content-Transfer-Encoding: binary');
      header('Expires: 0');

      exit;
    }
    else {
      echo "no such file: $file";
      die;
    }
  }

[igrr]

Since you're using HTTPS, you need to provide HTTPS certificate fingerprint as third argument to update.

igrr commented on Aug 3
not a redirect to another URL. I.e. response code has to be 20x and with binary file in the body of response.

Can you please fix this issue?
We will be able to use google drive etc...
It could be very very useful !!!

Thank you.

Hi, I got "HTTP_UPDATE_FAILD Error (-1): HTTP error: connection refused"
I use " t_httpUpdate_return ret = ESPhttpUpdate.update("http://10.10.10.20",80,"/ota.php");"
The php will give me the right file.
on CHROME it says "only for ESP8266 updater!" but I got error on esp.
Please help.

[pieman64]

@Cristianistrate doesn't the port need to be "80" rather than 80?
Are you able to provide details of the headers you are using in your sketch and your PHP script?

[Cristianistrate]

Tried "80". same error.

[kandev]

I guess the error is because you check for "HTTP_X_ESP8266_SKETCH_MD5" header.
Although it's written in all the examples around the net, it's never sent by ESP8266. Maybe it's bug, maybe I'm doing it wrong, but HTTP_X_ESP8266_SKETCH_MD5 header is missing on my ESPs.

[davisonja]

It's supplied if you're using the git version.

=============
I've tried it with 2 different ESP8266-12E chips - both give same results
I've tried running off fully charged 6V battery thru a 1amp 3.3v regulator
and running off bench supply set to deliver 1amp at 5v thru 1amp 3.3v regulator
Same problem every time. But works fine if I use http instead of https. almost seems like there's a bug in ESP8266httpUpdate, as it works with http, but not https. Also I suspect the following is the key message in the data above:

Fatal exception 29(StoreProhibitedCause):
epc1=0x4000e1b2, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

Anybody know what the fix is?
