+  Configuring the GNSS to automatically send MON COMMS reports over I2C and display them using a callback
+  By: Paul Clark
+  SparkFun Electronics
+  Date: Novenber 4th, 2024
+  License: MIT. See license file for more information.
+
+  This example shows how to configure the u-blox GNSS to send MON COMMS reports automatically
+  and access the data via a callback. No more polling!
+
+  Feel like supporting open source hardware?
+  Buy a board from SparkFun!
+  ZED-F9P RTK2: https://www.sparkfun.com/products/15136
+
+  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
