다른것없이 모듈작동유부를 확인하려면
모듈에 전원 연결하시고 창가에 두시면
led가 깜박거릴것입니다--> 이경우는 전원은 정상으로 연결된것입니다
만약 led 에 불이 안들어오면 전원선 연결이 잘못되것입니다
1~5분정도 지나서 led가 계속 켜져있으면 위성 정상 수신하여 신호를 출력하고 있는 상태입니다
시간이 지나도 led가 계속 깜박거리면 위성을 못잡은 상태입니다
하늘이 보이곳으로 이동하시거나 빽업밧데리 정상 연결하셨는지 확인하셔야 합니다
gps 모듈은 전제품 테스트 해서 판매한것입니다

밧데리 전압은 정상범위 입니다.

몇시간을 놔둬도 led는 계속 깜박이네요.


개활지로 나가서 확인해 봐야 하는건가요?

cp2102와  GPS 모듈을 연결하는 전선의 길이을 조금 길게해보세요.
CP2102의 노이즈 때문에 GPS 수신이 안좋아 지더군요...

그리고, GPs 모듈의 안테나가 하늘을 보도록 하면 더 빨리 잡히죠...

하늘이 조금만 보여도 됨니다
안테나(백색부분 현사진의 반대로) 부분이 위로 향해야 합니다

그럼 CP2102를 동박테이프로 완전 감싸주면 좋아질까요?

절연시트를 CP2102 기판의 위/아래를 방열판용 절연시트로 감싸고
그 위레 동박테이프를 완전 밀폐되도록 감싸주면 좋아지겠죠??


그나저나 주말이나 되야 차를 지상으로 끌고나와서 테스트 해볼낀데...

실내에서 하다보니 민폐만 끼치게되네요.
