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:

Sending files using OBEX Protocol
To send a file to a paired device use obexctl tool.
$ obexctl [obex]# connect <mac address> [obex]# send <file> [obex]# quit
For example, to send /etc/fstab file to a paired PC from the example above:
root@imx6ul-var-dart:~# 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.
