需要先开启 debian 系统中的 obex 服务

systemctl --user start obexsystemctl --user enable obex

确认 obex 服务正常工作

user@debian:/tmp$ systemctl --user status obex● obex.service - Bluetooth OBEX service     Loaded: loaded (/usr/lib/systemd/user/obex.service; enabled; preset: enabled)     Active: active (running) since Sat 2025-09-20 20:35:53 CST; 1h 9min ago Invocation: 279f5e1a454a428dbb07065246269cb2   Main PID: 117672 (obexd)      Tasks: 7 (limit: 54969)     Memory: 4.8M (peak: 5.7M)        CPU: 432ms     CGroup: /user.slice/user-1000.slice/user@1000.service/app.slice/obex.service             └─117672 /usr/libexec/bluetooth/obexduser@debian:/tmp$

就可以正常使用蓝牙发送文件给手机

假如手机发送文件给 Debian 系统 除了 pair
还需要 trust 手机设备的蓝牙地址 94:45:60:6D:XX:YY

user@debian:/tmp$ bluetoothctl hci0 new_settings: powered bondable ssp br/edr le secure-conn wide-band-speech cis-central cis-peripheral Agent registered[Pixel]> trust 94:45:60:6D:XX:YY

这样 手机就可以发送文件到 debian ，系统接受完成后顶部就会有提示
