I used to OTA sketches and data files using the ArduinoOTA and ESP32 sketch data Upload tools and the ESP32 devkit, for example when using the Arduino IDE.

Versions:

  • Arduino IDE- 1.8.19
  • ESP32 on Arduino IDE - 1.0.6
  • ArduinoOTA 1.0.9

Moving to PlatformIO-

Started a new project using the ESP32 devkit, ArduinoOTA was added from the registry to the project (also 1.0.9 as on Arduino IDE).

And now - when I tried to copy the BasicOTA example from the Arduino IDE's ArduinoOTA example, the compilation failed.

To make sure I don't have any library/version issues, I checked:

  1. WiFi, ESPmDNS is part of builtin.
  2. WiFiUdp was not found not inbuiltin,installed nor registry - not shown in dependency graph during compilation -- ??
  3. ArduinoOTA used from registry.
#include <WiFi.h>
#include <ESPmDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>

const char* ssid = "dvirz_iot";
const char* password = "GdSd13100301";

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 3232
  // ArduinoOTA.setPort(3232);

  // Hostname defaults to esp3232-[MAC]
  // ArduinoOTA.setHostname("myesp32");

  // No authentication by default
  // ArduinoOTA.setPassword("admin");

  // Password can be set with it's md5 value as well
  // MD5(admin) = 21232f297a57a5a743894a0e4a801fc3
  // ArduinoOTA.setPasswordHash("21232f297a57a5a743894a0e4a801fc3");

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

      // NOTE: if updating SPIFFS this would be the place to unmount SPIFFS using SPIFFS.end()
      Serial.println("Start updating " + type);
    })
    .onEnd([]() {
      Serial.println("\nEnd");
    })
    .onProgress([](unsigned int progress, unsigned int total) {
      Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
    })
    .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();
}

and got this compilation error:

All I can see are three issues (plus possible some bonus ones)

  1. You can't daisy chain callback setters like that, it returns void and it doesn't make any sense to have void.onProgress... and those callbacks doesn't seems to fit current library, so you should just drop them completely.
  2. There is no begin() without parameters. See examples.
  3. In the library I can see only callback setters: beforeApply, onError and onStart
  4. You might be missing #include <Arduino.h> (it doesn't have any preprocessor like ArduinoIDE that adds this to the first line without you knowing it
  5. You might be missing some defines (you can compare Arduino compile commands and Pio one)

Anyway you should take a look into the examples (at least begin is there). Callbacks looks like they are taken from who knows where (probably different library or so).

But they definitely must be complete like:

ArduinoOTA.onStart([](){ /* started */ });
ArduinoOTA.onBeforeApply([](){ /* before aply */ });

EDIT:

After some searching the ArduinoOTA library is directly in esp32 core (google: "arduinoOTA onProgress esp32"), so you don't have to add any lib_deps for ArduinoOTA. Or more likely you shouldn't add any, and the correct library will be used then. If not, you'll have to copy (or download) correct library into lib/ subdirectory.

  • Hi @KIIV - How can you explain the fact that the example is taken from ArduinoOTA library (when using Arduino IDE), compiles and works as it should ??

    Might be different library (or version). Sometimes the cores has libraries with them. You can always find its location and copy that library to the lib subdirectory in your project (and remove that lib_deps ArduinoOTA reference) to use correct version

If you check the ArduinoOTA library in Github it states that this library has not been tested on platformIO Also note that not all functions are the same, parameters are different when you call in ArduinoIDE and on PlatformIO
