안드로이드 커스텀 리모컨 키값 프로필 생성하기

category 안드로이드 2019. 8. 4. 15:22

안녕하세요? 


아래의 LG 리모컨을 활용해 보기 위해서 키값을 생성해보고 있습니다.







1. 리모컨 특징


앞면 뒷면 존재 뒷면에 풀 키보드 및 마우스 패드 존재


이어폰 기능 마이크 기능 존재


블루투스 페어링 시 키 페어링 이어폰 페어링 단계 있음


그런데 살짝 키반응은 느린편입니다 ㅎㅎㅎ..


<페어링 방법>

우측 아래 지우기 버튼 꾹 누르고 리모컨 초기화

가운데 U+ 메뉴 꾹 눌러 페어링 모드 진입

BT RCU 먼저 페어링

EARSET 페어링


페어링 후 아래의 2개 장비가 페어링 되어야합니다.






2. 안드로이드 키 값 프로파일 작성


이전에 볼륨 키 고장나서 홈키를 볼륨키로 쓴다거나 할 때.. /system/usr/keylayout/qwerty.kl 파일을 수정해 보신적이 있으실 껍니다. 그 방법을 활용하여 작성해 보는 것입니다.

AVRCP 는 블루투스 이어폰의 버튼 값을 나타내고 있습니다. 이걸 참고하여 작성해야하는데..


Vendor_046d_Product_c294.kl <-- 아니 벤더 프로덕트 이걸 어디서 찾는지 모르겠습니다.


그럼 /proc 을 뒤져서 찾아봐야합니다.

Vendor_00c4_Product_0080_Version_0213.kl 이런식으로 파일 이름을 작성하시면 됩니다.


대부분 버전은 빼고 넣습니다.


자 그럼 키 값은 어떻게 찾느냐..


일단 evtest 를 설치하고 /dev/input 으로 이동하여 이벤트가 몇개 있는지 봅니다. 그리고 cat eventX 하여 버튼을 누를때마다 반응하는 것이 있을 것입니다.

evtest 로 키 값 리스트와 눌러보면서 키값을 찾으실 수 있습니다.


그럼 Generic.kl 파일을 가져와서 수정 후 Vendor_00c4_Product_0080_Version_0213.kl 로 만들어 넣어주면 됩니다.
