一、使用的是开发板提供的固件 ：tina_t113-100ask_uart3.img，（后我拉取tina SDK自己编译结果一样）
二、问题描述
1、使用 /etc/bluetooth/bt_init.sh 命令启动蓝牙，报错，信息如下：
hcidump_xr start
/etc/bluetooth/bt_init.sh: line 92: hcidump_xr: not found

2、使用 /etc/bluetooth/bluetoothd start 启动蓝牙服务失败，报错如下：
root@TinaLinux:/# /etc/bluetooth/bluetoothd start
root@TinaLinux:/# ln: /var/lib/bluetooth: No such file or directory
bluetoothd[279]: Bluetooth daemon 5.54
D-Bus setup failed: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory
bluetoothd[279]: Unable to get on D-Bus
3、使用 hciattach -n ttyS1 xradio & 初始化蓝牙，报错，通信超时，信息如下：
root@TinaLinux:/# hciattach -n ttyS1 xradio &
root@TinaLinux:/# xradio_init
