如何连接蓝牙键盘

我正在尝试将蓝牙键盘与我的联想 Ideapad Z70-50 配对。

$ hcitool scan
Scanning ...

但什么也没找到，尽管我的键盘处于发现模式。该设备可以正常工作，因为我可以将其与平板电脑配对。我尝试提供以下设置的详细信息。

有什么建议吗？谢谢！

问题出在 wifi 中的 realtek 设备，请参阅Bus 002 Device 005: ID 0bda:b728 Realtek Semiconductor Corp. 此设备无法工作，但在您尝试使用其他 USB 蓝牙适配器时会导致它们出现问题。今天晚些时候，我可以为您构建一个 btusb.ko 模块，它将像我一样忽略 Realtek禁用内部 RTL8723 蓝牙

但是请为您的内核进行修改，因为我在此处发布的版本仅适用于 3.13.0-44。重启后，此版本仍有很小的可能性可以正常工作。

echo "install btusb /sbin/modprobe --ignore-install btusb && echo '0bda b728' > /sys/bus/usb/drivers/btusb/remove_id" | sudo tee /etc/modprobe.d/bcmbtusb.conf
