+  Get a device's I2C address using advanced getVal method

+
+  u-blox changed how to configure their modules in 2019. As of version 23 of the UBX protocol the
+  UBX-CFG commands are deprecated; they still work, they just recommend using VALSET, VALGET, and VALDEL
+  commands instead. This example shows how to use this new command structure.
+
+  Feel like supporting open source hardware?

+  Hardware Connections:
+  Plug a Qwiic cable into the GNSS and a RedBoard Qwiic or 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
