/* Send UBX binary commands to enable RTCM sentences on u-blox ZED-F9P module Based on Example7 By: Nathan Seidle SparkFun Electronics Updated by Paul Clark to demonstrate setVal8/16/32, newCfgValset8/16/32, addCfgValset8/16/32 and sendCfgValset8/16/32 Date: July 1st, 2019 License: MIT. See license file for more information but you can basically do whatever you want with this code. 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? Buy a board from SparkFun!
