  basically do whatever you want with this code.

  Ublox depricated many -CFG messages and replaced them with new
  VALGET, VALSET, VALDEL methods. This shows the basics of how to use
  these methods.

  Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!

  Feel like supporting open source hardware?
  Buy a board from SparkFun!

  SAM-M8Q: https://www.sparkfun.com/products/15106

  Hardware Connections:
  Plug a Qwiic cable into the GPS and a BlackBoard
  If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
  Open the serial monitor at 115200 baud to see the output
