DataLogic QBT2400 스캐너를 Linux 호스트 시스템(Kubuntu 22.04 상자)과 페어링하려고 합니다. 스캐너는 Bluetooth 직렬 포트 프로필을 지원해야 합니다.
스캐너가 보이지만 페어링이 항상 실패합니다. PIN이 1234여야 하는 공장 기본 설정으로 스캐너를 복원했지만 작동하지 않았습니다. 그런 다음 설명서에 설명된 대로(QR 코드를 스캔하여) 스캐너의 PIN을 다른 값으로 설정했지만 이 역시 실패했습니다.
그래서 뭔가 다른 문제가 있다고 가정하지만 추가로 디버깅하는 방법을 모르겠습니다.
이것은 내가 얻는 세션입니다.

블루투스 서비스에 대한 디버깅을 활성화했지만 (나에게) 유용한 것을 찾지 못했습니다.
