我的外部 CSR 适配器出现蓝牙问题。我可以使用lsusb
尝试通过以下方式手动启动守护进程：
sudo /usr/lib/bluetooth/bluetoothd -n
给我：
bluetoothd[5103]: Bluetooth daemon 5.40
bluetoothd[5103]: Starting SDP server
bluetoothd[5103]: Bluetooth management interface 1.12 initialized
bluetoothd[5103]: Failed to obtain handles for "Service Changed" characteristic
bluetoothd[5103]: Sap driver initialization failed.
bluetoothd[5103]: sap-server: Operation not permitted (1)
bluetoothd[5103]: Failed to set mode: Blocked through rfkill (0x12)
任何帮助将不胜感激。
