Procedure to connect to WiFi access point through web interface when no saved access point is available

[mhurk]

Currently you need to hardcode your SSID and password in the code

For example via:
For Arduino-ESP32, WiFiManager is effectively the standard. (apparently)

Features

• SoftAP provisioning
• Captive portal (DNS redirect)
• SSID scan + dropdown
• Automatic reconnect
• Reset on button press

#include <WiFiManager.h>

WiFiManager wm;

void setup() {
  bool res;
  res = wm.autoConnect("MyDevice-Setup");

  if (!res) {
    ESP.restart();
  }
}

This

• Creates AP MyDevice-Setup
• Serves portal at 192.168.4.1
• Saves credentials in flash
• Automatically connects on next boot
