Ubuntu蓝牙Bluetooth命令行连接发送文件完整流程

1.确保bluez已安装好
$sudo apt install bluez

2.查看当前蓝牙阻塞状态
$sudo rfkill list

如果上面阻塞状态为yes,表示蓝牙关闭,则需要unblock打开蓝牙：
$sudo rfkill unblock bluetooth

3.执行bluetoothctl
$bluetoothctl

4.扫描其他蓝牙设备
$scan on

5.配对指定的蓝牙设备
$pair AA:AA:xxxxxx
$trust dev_address

pair 58:85:e9:2e:52:2a
trust 58:85:e9:2e:52:2a
connect 58:85:e9:2e:52:2a

6.如果没有安装bluez-tools则需要安装

$sudo apt install bluez-tools
使用bt-obex发送文件：
$bt-obex -p [remote_mac] [file]

譬如：
$bt-obex -p F0:6B:CA:A2:C4:69 ~/xxx.pdf
bt-obex -p 58:85:e9:2e:52:2a ~/readme.pdf

命令行监听接收则可以先执行命令：
$bt-obex -s [path]

譬如：
$bt-obex -s ~/Downloads
