Bluetooth File Transfer

Pairing with Bluetooth device

To send files to each other two bluetooth devices should be paired first. Use bluetoothctl tool to manage the pairing 

# bluetoothctl
[bluetooth]# power on
[bluetooth]# pairable on
[bluetooth]# scan on

Copy mac address

[bluetooth]# scan off
[bluetooth]# pair <mac address>

Approve pairing on Device if required

[bluetooth]# trust <mac address>
[bluetooth]# quit

For example when pairing with a PC the following is done: 

# bluetoothctl

[bluetooth]# power on
[CHG] Controller 96:93:E0:47:39:89 Class: 0x300100
Changing power on succeeded
[CHG] Controller 96:93:E0:47:39:89 Powered: yes
[bluetooth]# pairable on
Changing pairable on succeeded
[bluetooth]# scan on

Sending files using OBEX Protocol

To send a file to a paired device use obexctl tool. 

# DBUS_SESSION_BUS_ADDRESS=unix:path=/var/run/dbus/system_bus_socket obexctl
[obex]# connect <mac address>
[obex]# send <file>
[obex]# quit
Please when running send command remember to provide absolute path

For example, to send /etc/fstab file to a paired PC from the example above: 

# DBUS_SESSION_BUS_ADDRESS=unix:path=/var/run/dbus/system_bus_socket obexctl 
[NEW] Client /org/bluez/obex 
[obex]# connect 00:1A:7D:DA:71:0B
Attempting to connect to 00:1A:7D:DA:71:0B
[NEW] Session /org/bluez/obex/client/session0 [default]
[NEW] ObjectPush /org/bluez/obex/client/session0 
Connection successful
[00:1A:7D:DA:71:0B]# send /etc/fstab
Attempting to send /etc/fstab to /org/bluez/obex/client/session0
[NEW] Transfer /org/bluez/obex/client/session0/transfer0 
Transfer /org/bluez/obex/client/session0/transfer0
        Status: queued
        Name: fstab
        Size: 637
        Filename: /etc/fstab
        Session: /org/bluez/obex/client/session0
[CHG] Transfer /org/bluez/obex/client/session0/transfer0 Status: complete
[DEL] Transfer /org/bluez/obex/client/session0/transfer0

Receiving files using OBEX Protocol

No special action is required to receive a file that was sent from a paired device. The file will be stored under /tmp/bluetooth-inbox.
