/*
Reading lat and long via UBX binary commands using an RX-only UART

basically do whatever you want with this code.
This example shows how to configure the library for serial port use with a single wire connection using the assumeAutoPVT method.
Saving your pins for other stuff :-)
Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!
Feel like supporting open source hardware?

Preconditions:
U-Blox module is configured to send cyclical PVT message
Hardware Connections:
Connect the U-Blox serial TX pin to Rx of Serial2 (default: GPIO16) on your ESP32
Open the serial monitor at 115200 baud to see the output

//Use any Serial port with at least a Rx Pin connected or a receive only version of SoftwareSerial here
//Assume that the U-Blox GPS is running at 9600 baud (the default)
Serial2.begin(9600);
// no need to check return value as internal call to isConnected() will not succeed
myGPS.begin(Serial2);
// tell lib, we are expecting the module to send PVT messages by itself to our Rx pin
// you can set second parameter to "false" if you want to control the parsing and eviction of the data (need to call checkUblox cyclically)

// if implicit updates are allowed, this will trigger parsing the incoming messages
// and be true once a PVT message has been parsed
// In case you want to use explicit updates, wrap this in a timer and call checkUblox as often as needed, not to overflow your UART buffers
