/*
  AT Firmware simulation example

  Use the serial monitor to interface with the AT firmware. For instance, to scan for WiFi:

AT+CWMODE=1
AT+CWLAP

  Connect to WiFi:

AT+CWJAP="Wokwi-GUEST",

  Show the current IP address:

AT+CIFSR

  Show firmware version

AT+GMR

  To show list list of available commands:

AT+CMD?
