Hello, I currently store the ssid and password in the EEPROM, but I always do it with Arduino IDE.
I want to take my inventions to my friend's house and configure the Wi-Fi network data without using the laptop and uploading the sketch again.
I want to write in the EEPROM through a cable and mobile (for example) with an app in Java or Kotlin.
Is it possible to do that ? Is there another way?
