  This example shows how to reset the U-Blox module to factory defaults.

  Hardware Connections:
  Connect the U-Blox serial port to Serial1
  If you're using an Uno or don't have a 2nd serial port (Serial1), consider using software serial
  Open the serial monitor at 115200 baud to see the output
