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. Tera Term has TCP/IP support built-in:
