GETTING STARTED Configuring the Firmware You should never need to change most of the firmware settings, the default settings will meet the needs of almost all users. However, one option you may want to change is “TCP Server (IPS1)”. This is disabled by default. When it is enabled, it allows you to access the firmware console via TCP - over Ethernet or Ethernet-over-USB - instead of CONFIG ESP32 Serial.
