Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino
란 오류가 브링업 패키지 실행 후 뜹니다.
제 생각에는 a/s 부품 수리 후 검증을 위해 버전을 바꾼 것 같은데 원래대로 되돌리거나 버전을 맞추는 방법에 대해서 아시는 분 있으신가요
The error you are reporting indicates a version mismatch between your rosserial and Arduino packages. If you aren’t sure exactly what versions you need to be on, I would recommend reaching out to the maintainers/community of rosserial to check.
