Why i cant run simple coding of gps neo 6m sensor with esp32c3 xiao? help me
I think the problem is with the hardware serial…
different hardware uses serial differently
FYI
This is from my archive, havent tested in a while, some custom edits but may give you some ideas if you review the code
#include <TinyGPSPlus.h>
#include <SoftwareSerial.h>
/*
This sample code demonstrates just about every built-in operation of TinyGPSPlus (TinyGPSPlus).
It requires the use of SoftwareSerial, and assumes that you have a
9600-baud serial GPS device hooked up on pins 7(rx) and 6(tx).

Hi there,
Not sure if it will help you , but I have a demo with the Xiao nrf52 here working , may help
HTH
GL 
PJ
but it say i cant use software serial? is there library need to installed?
Make sure you have the XIAO ESP32C3 selected as Board at compile time
Also there is a difference between TineyGPS++ and Tiny GPSPlus
Also i see a TinyGPSPlus-ESP32 which may be optomized for esp32
You can see this tutorial and cross-check with your method: View location data sent by NEO-M6 GPS using ESP32 board
