- Sun Oct 04, 2015 10:07 am #30469 If you have the latest staging code, you can take a look at the ESP8266HTTPUpdateServer example.

- Mon Oct 05, 2015 8:38 am #30538 Tried WebUpdate example but without success
Sketch:

Code: Select all#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>

const char* host = "esp8266-webupdate";
const char* ssid = "Telecom-00000000";
const char* password = "telecomitalia123456789012345";

ESP8266WebServer server(80);
const char* serverIndex = "<form method='POST' action='/update' enctype='multipart/form-data'><input type='file' name='update'><input type='submit' value='Update'></form>";

void setup(void){
  Serial.begin(115200);
  Serial.println();
  Serial.println("Booting Sketch...");
  WiFi.mode(WIFI_AP_STA);
  WiFi.begin(ssid, password);
  if(WiFi.waitForConnectResult() == WL_CONNECTED){
    MDNS.begin(host);
    server.on("/", HTTP_GET, [](){
      server.sendHeader("Connection", "close");
      server.sendHeader("Access-Control-Allow-Origin", "*");
      server.send(200, "text/html", serverIndex);
    });
    server.onFileUpload([](){
      if(server.uri() != "/update") return;
      HTTPUpload& upload = server.upload();
      if(upload.status == UPLOAD_FILE_START){
        Serial.setDebugOutput(true);
        WiFiUDP::stopAll();
        Serial.printf("Update: %s\n", upload.filename.c_str());
        uint32_t maxSketchSpace = (ESP.getFreeSketchSpace() - 0x1000) & 0xFFFFF000;
        if(!Update.begin(maxSketchSpace)){//start with max available size
          Update.printError(Serial);
        }
      } else if(upload.status == UPLOAD_FILE_WRITE){
        if(Update.write(upload.buf, upload.currentSize) != upload.currentSize){
          Update.printError(Serial);
        }
      } else if(upload.status == UPLOAD_FILE_END){
        if(Update.end(true)){ //true to set the size to the current progress
          Serial.printf("Update Success: %u\nRebooting...\n", upload.totalSize);
        } else {
          Update.printError(Serial);
        }
        Serial.setDebugOutput(false);
      }
      yield();
    });
    server.on("/update", HTTP_POST, [](){
      server.sendHeader("Connection", "close");
      server.sendHeader("Access-Control-Allow-Origin", "*");
      server.send(200, "text/plain", (Update.hasError())?"FAIL":"OK");
      ESP.restart();
    });
    server.begin();
    MDNS.addService("http", "tcp", 80);
 
    Serial.printf("Ready! Open http://%s.local in your browser\n", host);
  } else {
    Serial.println("WiFi Failed");
  }
}
 
void loop(void){
  server.handleClient();
  delay(1);
}

Serial monitor output:

Update: Blink.ino

Are you trying to upload the source code of your sketch instead of the compiled binary (ie.: Blink.bin) ?
