+  Send UBX binary commands to enable RTCM sentences on u-blox NEO-M8P module
+  By: Nathan Seidle
+  SparkFun Electronics
+  Date: September 7th, 2018
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example sends the command to enable the four RTCM messages needed for RTK. This 
+  is the first part of a larger tutorial and example to setup an RTK base station.
+  These commands are only accepted by the NEO-M8P module.
+ 
+  Feel like supporting open source hardware?
+  Buy a board from SparkFun!
+  ZED-F9P RTK2: https://www.sparkfun.com/products/15136
+  NEO-M8P RTK: https://www.sparkfun.com/products/15005
+  SAM-M8Q: https://www.sparkfun.com/products/15106
+
+  Hardware Connections:
+  Plug a Qwiic cable into the GNSS 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
