안녕하세요 아두이노 메가보드와 블루투스 와이파이 gps 모듈을 이용하여 웹서버 구글 지도에 gps 좌표를 찍는 것을 목표로 하고 있는 학생입니다. 아래에 코드를 올렸는데 네이버 블로그를 참고하여 코드를 작성해봤습니다. 계속해서 오류코드가 뜨는데 라이브러리 문제인지 어떤 문제인지 알 수가 없네요 ㅠㅠ 도움 부탁 드립니다.
오류코드는 다음과 같습니다.
C:\Users\shin dongkyu\Desktop\NeoGPS-master\sketch_aug31a\sketch_aug31a.ino: In function 'void wifi_connect(ESP8266&, bool&)':
