Need code for ota http sever

Projects Programming
1

when i compile the compiler gives me waring says,

'class ESP32HTTPUpdate' has no member named 'setup'

my ota code is,


ArduinoOTA.setPort(8266);

OTA_httpUpdater.setup(&OTA_httpServer);
OTA_httpServer.begin();
ArduinoOTA.setHostname("LCS_TM");

ArduinoOTA.onStart([]() {
  String type;
  if (ArduinoOTA.getCommand() == U_FLASH) {
    type = "sketch";
  } else { // U_FS
    type = "filesystem";
  }
});
ArduinoOTA.begin();

also if i put the code before wifi.begin the esp will infinite crash.

any suggestions?

here is my whole program, the update server should be on port 81 but for some reason its on port 80 when i try on port 81 it says file not found

if i remove "OTA_httpUpdater.setup(&OTA_httpServer);" from ota the page loads on port 80. it allows me to upload the file but does not reset or retain the new program?

i ran this example,

#include <Arduino.h>

#include <WiFi.h>

#include <HTTPClient.h>
#include <ESP32httpUpdate.h>

#define USE_SERIAL Serial

void setup() {

    USE_SERIAL.begin(115200);
    // USE_SERIAL.setDebugOutput(true);

    USE_SERIAL.println();
    USE_SERIAL.println();
    USE_SERIAL.println();

    for(uint8_t t = 4; t > 0; t--) {
        USE_SERIAL.printf("[SETUP] WAIT %d...\n", t);
        USE_SERIAL.flush();
        delay(1000);
    }

    WiFi.begin("SSID", "PASSWORD");

}

void loop() {
    // wait for WiFi connection
    if((WiFi.status() == WL_CONNECTED)) {

        USE_SERIAL.println("Update SPIFFS...");
        t_httpUpdate_return ret = ESPhttpUpdate.updateSpiffs("http://server/spiffs.bin");
        if(ret == HTTP_UPDATE_OK) {
            USE_SERIAL.println("Update sketch...");
            ret = ESPhttpUpdate.update("http://server/file.bin");

            switch(ret) {
                case HTTP_UPDATE_FAILED:
                    USE_SERIAL.printf("HTTP_UPDATE_FAILED Error (%d): %s", ESPhttpUpdate.getLastError(), ESPhttpUpdate.getLastErrorString().c_str());
                    break;

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

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

my http server log just show it requesting "spiffs.bin" over and over again. the file exists on the server and is accessible. the esp will not update what am i doing wrong. i really dont want to poll for an update file. i really want to update from my update.html file. someone please help

i just used the GitHub - ayushsharma82/AsyncElegantOTA: Perform OTAs for ESP8266 / ESP32 Elegantly! Uses AsyncWebServer and it worked. this requires asyncWebserver. my code is not directly compatible with async. why dont it work the other 2 ways?

There does not seem to be much support for http ota on the esp32. there are just a few ways i found on google and most of them dont work. its jsut one problem after the next. i am at a screeching halt idk what to do

5

i tried to use this library esp32-http-update/examples at master · suculent/esp32-http-update · GitHub

its piss poor examples of http update do not work. this is a port from esp8266 version which i used and works on esp8266 but on esp32 i get error mention in very first post.

i can confirm that the server opens the port 81. but it does not attach updating service because of error.

someone has got to know something about this.

6

it would be nice to get some help around here. i guess no one here knows anything about esp32? i doubt it. love wasting all my time !!!

Hi,

This forum is a 24/7 place, so a suitable answer from an informed forum member may take time.

Sorry I am not fully into network systems, ESP32 yes, but only basic WiFi connections.

There are people here who can probably help you, but be patient, your helper may still be at work or bed.

Have you looked on the "Randon Nerd" website?

Thanks.. Tom.. :grinning: :+1: :coffee: :australia:

yes i looked. as much as it may seem like it , this is not the first place i come as soon as i have a problem. i really hate asking questions here so much.

bump

10

Please help i really need ota to work.

11

This example works the way i want it, as a matter a fact its the only ota example that works at all.

#include <WiFi.h>
#include <AsyncTCP.h>
#include <ESPAsyncWebServer.h>
#include <AsyncElegantOTA.h>

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

AsyncWebServer server(80);


void setup(void) {
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  Serial.println("");

  // Wait for connection
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.print("Connected to ");
  Serial.println(ssid);
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());

  server.on("/", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(200, "text/plain", "Hi! I am ESP32.");
  });

  AsyncElegantOTA.begin(&server);    // Start ElegantOTA
  server.begin();
  Serial.println("HTTP server started");
}

void loop(void) {
  AsyncElegantOTA.loop();
} server.onNotFound i been asking for help for 20 hours
12

If i donate money to your forum will you help me? what does it take

13

there,i donated money now please help me

14

none of your attempts look anything like the elegantota examples given in the lib
this works perfectly on my esp32 dev board, i would start from there

#include <WiFi.h>
#include <WiFiClient.h>
#include <WebServer.h>
#include <ElegantOTA.h>

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

WebServer server(80);


void setup(void) {
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  Serial.println("");

  // Wait for connection
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.print("Connected to ");
  Serial.println(ssid);
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());

  server.on("/", []() {
    server.send(200, "text/plain", "Hi! I am ESP32.");
  });

  ElegantOTA.begin(&server);    // Start ElegantOTA
  server.begin();
  Serial.println("HTTP server started");
}

void loop(void) {
  server.handleClient();
}

YOU are a life saver. too bad theresno way to add karma. that is a different library that the elegant library i was using. thankyou soo much!!

16

I got AsyncElegantota from here ESP32 OTA (Over-the-Air) Updates - AsyncElegantOTA Arduino | Random Nerd Tutorials

i was not aware of a non async elegantota thankyou soo much!!
