ArduinoOTA Raspberry Pi Pico W - Error Uploading

Projects Programming
1

I want to update the Raspberry Pi with new codes using ArduinoOTA. Previously, I downloaded the Raspberry Pi Pico Arduino core. The Pico connects to the WiFi without any issues, but when I try to upload a new code (in this case, a simple blink code), it attempts to upload but fails. I don't know what the problem is since the BasicOTA code also does not work over WiFi.
I have enabled the TCP port 2040 (default) on my router and in my firmware and I can successfully ping the Pico's IP address.

My goal is to wirelessly update the Pico W with new codes using Arduino. I have only come across the OTA method in Arduino

#include <ArduinoOTA.h>
#include <LEAmDNS.h>
#include <WiFiUdp.h>
#include <WiFi.h>
#include <LittleFS.h>  
#include "secret.h"


const char* ssid = SSID;
const char* password = PW;


void setup() {
  Serial.begin(115200);

  pinMode(LED_BUILTIN, OUTPUT);

  connectToWiFi();

  if (!LittleFS.begin()) {
    Serial.println("LittleFS could not be mounted. Please check the configuration.");
  } else {
    Serial.println("LittleFS successfully initialized.");
  }

  // ArduinoOTA.setPort(2040);

  // OTA Setup
  ArduinoOTA.setHostname("xxx");  

  ArduinoOTA.onStart([]() {
    String type;
    if (ArduinoOTA.getCommand() == U_FLASH) {
      type = "sketch";
    } else {
      type = "filesystem";  // LittleFS Filesystem OTA Command
    }

    Serial.println("Starting OTA update: " + type);
  });

  ArduinoOTA.onEnd([]() {
    Serial.println("\nOTA update completed");
  });

  ArduinoOTA.onProgress([](unsigned int progress, unsigned int total) {
    Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
  });

  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();
}


void loop() {
  ArduinoOTA.handle();
  delay(10);

  // blink();
}

Output after the first upload via USB

WiFi connected
Assigned IP address: 192.168.1xx.xx
LittleFS successfully initialized.
OTA server at: xxx.local:2040

Output after the upload over WiFi with the "blink();" function

Is Verbose turned on? That amount of info is going to be very difficult.

Hey thanks for answering. :blush:
ArduinoOTA which is included in the bundle (GitHub - earlephilhower/arduino-pico: Raspberry Pi Pico Arduino core, for all RP2040 boards) does not work. You have to uninstall it and set up ArduinoOTA/ at master · JAndrassy/ArduinoOTA · GitHub
instead. It took a while but it works now. My current problem is only that Arduino rarely finds the network port :expressionless:
