I started using Arduino IDE and looks good for me but cannot find any solution to setup wireless information.

My device needs to boot in AP mode for first time so I can enter SSID and password and then it should restart, continue in client mode and connect to router. Is there any working example that can help me for this purpose?

I think that this is good option for You:
https://github.com/tzapu/WiFiManager

Code: Select all

#include <WiFiClient.h>
#include <EEPROM.h>
#include <ESP8266mDNS.h>
#include <WifiManager.h>

WiFiManager wifi(0);

void setup() {
  Serial.begin(115200);
  delay(10);
  Serial.println("INIT");
  
  wifi.autoConnect("AP_FOR_CONF");

  Serial.println("DONE");
}

void loop() {
}

Thank you. That is exactly what I need.
But it doesn't work as expected.

It starts in AP mode, and I successfully enter SSID and Password. It resets by itself, reads ssid and password from EEPROM and connects to network successfully. But as soon as I reset my ESP-01 manually it reads false data from EEPROM and starts AP again.
Hmmmm...

EDIT:

Here is what I get when I restart module manually:

Code: Select all

AutoConnect
Reading EEPROM SSID
SSID: 
��?�ntX<script>function
Reading EEPROM Password
Password: 
 c(l){document.getElementById('s').value=l.innerText||l.textCont
Waiting for Wifi to connect

Could not connect to WiFi
Started Soft Access Point

WiFi connected

Looks like reading from EEPROM is not good.

I think you'll find that the EEPROM functionality was broken in a recent release

Write a little program to write to the EEPROM (don't forget the EEPROM.commit())
Power down & up
Write another little program to read from the EEPROM.

I think you'll get garbage
