i dont even know where arduino stores the bin file after its compiled

@jwarnes71

To see the bin file location open File > Preferences, look for “Show verbose output during:” and check out “compilation” option. Full process is explained here.

There is a small graph about the flash layout :

https://github.com/esp8266/Arduino/blob ... ash-layout

Is your ESP has 512K or more ? Old ESP-12 have 512K, newer ones have 4M.
Because, effectively, if you have a 512K, you can not do OTA with sketch of that size.

Hello,
Here is some news about OTA:
Now i work on linux (lubuntu 14.10).
I use Arduino 1.6.10
I use stable librairies.

Here is my code :

Code: Select all#include <ESP8266WiFi.h>
#include <ESP8266mDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>

const char* ssid = "aaaaaaaaa";
const char* password = "bbbbbbbbbb";
boolean OTAProgress = false;
#define HOSTNAME "WiWiRe-OTA-"


char* strToChar(String s) {
  unsigned int bufSize = s.length() + 1; //String length + null terminator
  char* ret = new char[bufSize];
  s.toCharArray(ret, bufSize);
  return ret;
}

void setup() {
  Serial.begin(115200);
  Serial.println("Booting");
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  while (WiFi.waitForConnectResult() != WL_CONNECTED) {
    Serial.println("Connection Failed! Rebooting...");
    delay(5000);
    ESP.restart();
  }

  // Port defaults to 8266
  ArduinoOTA.setPort(8266);

  Serial.println("\r\n");
  Serial.print("Chip ID: 0x");
  Serial.println(ESP.getChipId(), HEX);

  // Set Hostname.
  String hostname(HOSTNAME);
  hostname += String(ESP.getChipId(), HEX);
  WiFi.hostname(hostname);

  // Print hostname.
  Serial.println("Hostname: " + hostname);
  //Serial.println(WiFi.hostname());

  // Hostname defaults to esp8266-[ChipID]
  ArduinoOTA.setHostname(strToChar(hostname));

  // No authentication by default
  //ArduinoOTA.setPassword((const char *)"xxxxxx");
    Serial.printf("Taille du programme : %u\n", ESP.getSketchSize());
    Serial.printf("Taille disponible : %u\n", ESP.getFreeSketchSpace());
    Serial.printf("Taille du chipset : %u\n", ESP.getFlashChipSize());
    Serial.printf("Taille réelle du chipset : %u\n", ESP.getFlashChipRealSize());
    Serial.printf("Type de mémoire du chipset : %u\n", (ESP.getFlashChipId(), HEX));
  ArduinoOTA.onStart([]() {
    Serial.println("Start");
  });
  ArduinoOTA.onEnd([]() {
    Serial.println("\nEnd");
    Serial.println("\nWaiting for reboot .");
    pinMode(2,OUTPUT);
    digitalWrite(2,HIGH);
    int i;
    int n;
    // Code to get some value of "n"

    for (i = 0; i < 8; i++) {// Loop to do "something" n times
      Serial.print(".");
      pinMode(2,OUTPUT);
      digitalWrite(2,HIGH);
      delay(500);
      Serial.print(".");
      digitalWrite(2,LOW);
      delay(500);
    }
    ESP.restart();
  });
  ArduinoOTA.onProgress([](unsigned int progress, unsigned int total) {
    if (OTAProgress != true){
     //Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
     Serial.printf("Progress: .");
     OTAProgress = true;
    } else {
     Serial.printf(".");
    }
  });
  ArduinoOTA.onError([](ota_error_t error) {
    Serial.printf("Error[%u]: ", error);
    if (error == OTA_AUTH_ERROR) Serial.println("Auth Failed");
    else if (error == OTA_BEGIN_ERROR) Serial.println("Begin Failed");
    else if (error == OTA_CONNECT_ERROR) Serial.println("Connect Failed");
    else if (error == OTA_RECEIVE_ERROR) Serial.println("Receive Failed");
    else if (error == OTA_END_ERROR) Serial.println("End Failed");
  });
  ArduinoOTA.begin();
  Serial.println("Ready");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  ArduinoOTA.handle();
  yield();
}


I lauch update with :

I can't get it work correctly ....
If you have any idea ....
Thanks,
Best regards

can you OTA upload through the IDE?

Not at all,
IDE always ask me for a password (wich is not set)

Heres is what i tried on IDE :
Board V1.6.5xxx
Board 2.0
Board 2.1
Board 2.2
Board 2.3
Board 2.3RC2
ESP8266 dev board

I tried with ESP07, ESP12F ESP14

Whatever i always get error pending upload , but not at same time , sometime 1% , sometime 25%

I also tried with windows , but .... i cant get python working well

Is there something i mess ?
