This example shows how to configure the u-blox GNSS to send MON COMMS reports automatically
9+
and access the data via a callback. No more polling!
10+
11+
Feel like supporting open source hardware?
12+
Buy a board from SparkFun!

ZED-F9P RTK2: https://www.sparkfun.com/products/15136
14+
15+
Hardware Connections:
16+
Plug a Qwiic cable into the GPS and a BlackBoard
17+
If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
18+
Open the serial monitor at 115200 baud to see the output
