ESP Cam issue Error 0x106

[learnerpowpow]

I am using Seeed Studio XIAO ESP32S3 board with it's official camera extension (OV3660 camera)
Few months ago, I tried official example code (File → Examples → ESP32 → Camera → CameraWebServer) and It worked as it should have

#include "esp_camera.h"
#include <WiFi.h>

// ===========================
// Select camera model in board_config.h
// ===========================
#include "board_config.h"

// ===========================
// Enter your WiFi credentials
// ===========================
const char *ssid = "**********";
const char *password = "**********";

void startCameraServer();
void setupLedFlash();

void setup() {
  Serial.begin(115200);
  Serial.setDebugOutput(true);
  Serial.println();

#endif
  }

  // camera init
  esp_err_t err = esp_camera_init(&config);
  if (err != ESP_OK) {
    Serial.printf("Camera init failed with error 0x%x", err);
    return;
  }

  sensor_t *s = esp_camera_sensor_get();
  // initial sensors are flipped vertically and colors are a bit saturated
  if (s->id.PID == OV3660_PID) {
    s->set_vflip(s, 1);        // flip it back
    s->set_brightness(s, 1);   // up the brightness just a bit

  WiFi.begin(ssid, password);
  WiFi.setSleep(false);

  Serial.print("WiFi connecting");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");

  startCameraServer();

  Serial.print("Camera Ready! Use 'http://");
  Serial.print(WiFi.localIP());
  Serial.println("' to connect");
}

void loop() {
  // Do nothing. Everything is done in another task by the web server
  delay(10000);
}

but now, I am trying to use that same code again, but this time the result was this
E (5025) i2c.master: probe device timeout. Please check if xfer_timeout_ms and pull-ups are correctly set up E (6025) i2c.master: probe device timeout. Please check if xfer_timeout_ms and pull-ups are correctly set up

does anyone know how to fix this?

Hello @learnerpowpow

Your topic was moved to its current location as it is more suitable.

Could you also take a few moments to Learn How To Use The Forum.

It will help you get the best out of the forum in the future.

Thank you

That is likely a loose camera cable if you have NOT modified the code, otherwise it may be the wrong camera selected.

[learnerpowpow]

I reseated the camera cable and tried again, but the error still shows up

[sonofcy]

I have used that sketch and it works fine.
Did you fill in the SSID and password before trying to run it?
If you did you need to post the rest of the code in board_config.h
Did you adjust the camera selector in board_config.h if it is needed?
If you did and still get an error, please post the entire verbose compiler output also in code tags.
Are you using the official code from XIAO? Here is where that is.

Did you change this
