저는 FC35를 실행 중이고 RealTek 8761b 칩셋 기반의 USB 어댑터 Bluetooth 어댑터를 연결했습니다. FC35는 /lib/firmware/rtl_bt 디렉토리에 다음 펌웨어와 함께 제공됩니다.
-rw-r--r--. 1 root root 80 Oct 28 09:19 rtl8761b_config.bin.xz
-rw-r--r--. 1 root root 21460 Oct 28 09:19 rtl8761b_fw.bin.xz
시작 시 dmesg는 동글에 대해 다음을 표시합니다.
[ 1.218007] usb 7-1: New USB device found, idVendor=2550, idProduct=8761, bcdDevice= 2.00
[ 1.218013] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 1.218016] usb 7-1: Product: Bluetooth Radio
[ 1.218019] usb 7-1: Manufacturer: Realtek
[ 1.218021] usb 7-1: SerialNumber: 00E04C239987
이제 bluetoothctl을 실행하고 list 명령을 실행하면 다음이 표시됩니다.
Controller 00:E0:4C:19:73:74 myhost.com [default]
bluetoothctl에서 BT 동글에 장치를 검색하라고 지시했지만 아무것도 찾지 못했습니다. 범위 내에 몇 가지 장치를 가져와서 페어링할 블루투스 키보드를 설정했지만 여전히 결과가 없습니다.
내 dmesg에 8761b 펌웨어 로딩에 대한 메시지가 포함되어야 합니까? (그런 메시지는 본 적이 없습니다.) - 어쩌면 단서일까요?
고쳐 쓰다:
modinfo를 사용하여 커널 모듈이 내 시스템에 있는 펌웨어 파일을 참조하지 않는 것을 발견했습니다! (rtl8761b가 아닌 rtl8761a를 참조합니다.) 왜 안 됩니까? 이것이 제가 수정해야 할 사항입니다.
