The following code shows how to use Grove UART port:
[https://www.seeedstudio.com/USB-To-Uart-5V%263V3-p-
to read the Grove UART port data.
GNSS
MC20 module provides the AT Commands Set for MCU to communicate with its
GSM/GPRS, GNSS and Bluetooth modules.
And we have installed a well written library for the Wio GPS, for simple applications
you even don't need to know much about how to use the AT commands, which is
complex and hard to read.
The following example shows how to read longitude and latitude and print them out
in Serial Monitor. Please note that Wio Tracker should be placed outdoor to get GPS

Warning
If both SerialUSB and SerialDBG are used in the code, please open SerialUSB's com port when
using, otherwise SerialDBG will not work.
