的蓝牙连接存在问题，查看服务发现：

service bluetooth status

存在Sap driver initialization failed 错误提示字样；网络上查找解决方案后，最终添加参数解决。具体修改为：

yangjk@yangjk-PC:~$ systemctl status bluetooth.service 
● bluetooth.service - Bluetooth service
     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)

             └─2565 /usr/lib/bluetooth/bluetoothd --noplugin=sap

yangjk@yangjk-PC:~$ cat /usr/lib/bluetooth/bluetoothd.sh
#! /bin/sh

if [ -d /usr/share/bluetooth ];then
        tmp=$(cat /usr/share/bluetooth/bluetoothd.conf |grep -wi OParameter)
        param=${tmp#*=}
        echo $param
fi
/usr/lib/bluetooth/bluetoothd --noplugin=sap $param

修改/usr/lib/bluetooth/bluetoothd.sh ，添加--noplugin=sap参数。
