If you do not have a router near you, or if you are outdoors, you can annotate the following code, and then
compile and upload it to ESP32-S3. And you can display the video images on your phone by Method 1.
/////////////////////////////////////////////////////
WiFi.begin(ssid_Router, password_Router);
Serial.print("Connecting ");
Serial.print(ssid_Router);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
WiFi.begin(ssid_Router, password_Router);
}
Serial.println("");
Serial.println("WiFi connected");
