I have installed Bluetooth dongle software and with the help of commands (using a terminal), I want to send and receive files from a smartphone.

How can I pair my devices and send files over Bluetooth using Terminal?

Send files:

bluetooth-sendto --device=12:34:56:78:9A:BC filename

To know your device name (12:34:56:78:9A:BC), you can issue this command:

hcitool scan

Receive files:

Haven't found it yet, but will let you know if it can be done using terminal

edit:

it looks like it can't be done through terminal. Blueman seems to do the trick but it's in GUI

I tested this with Ubuntu Bionic Beaver (18.04) and Android Lollipop.

  1. Ubuntu. Install the needed packages:

    sudo apt install bluez bluez-tools

    bluez-tools come with the following tools: bt-adapter bt-agent bt-device bt-network

  2. Ubuntu. Turn on the visibility:

    bt-adapter --set Discoverable 1

  3. Smartphone. Scan for remote devices to ID your Ubuntu machine.

  4. Ubuntu. Prep for managing incoming requests interactively with:

    bt-agent

  5. Pair devices:

    1. Smartphone. Initiate pairing request;

    2. Ubuntu. Accept the request from the bt-agent screen.

  6. Ubuntu. Send files to smartphone with: 

    bt-obex -p [remote_mac] [file]

    where [remote_mac] is the mac address of the smartphone. For example:

    bt-obex -p F0:6B:CA:A2:C4:69 ~/book.pdf

  7. Receive files from your smartphone:

    1. Ubuntu First create a Bluetooth file (obex) server:

      bt-obex -s [path]

      [path] is where to download files. For example:

      bt-obex -s ~/Downloads

    2. Smartphone. Send the file;

    3. Ubuntu. Accept the request from the bt-agent screen.

    Still, the bt-obex command is non-interactive, asking to type 'y' for each file to be accepted, which can be annoying. However, as it is a command-line tool, you can create a long file `yyy.txt` containing only lines with the y letter, and then run: `cat yyy.txt | bt-obex -s ~/Downloads`. Your computer will accept all files over bluetooth without asking! – dominecf Aug 28 '19 at 20:03

    Alternatively, you could use the `yes` command – vcapra1 Feb 03 '20 at 13:38
  • Thanks for this! I also had to install the `bluez-obexd` package. My received files also ended up in `$USER/.cache/obexd/` rather than the specified directory. – Neil Stockbridge May 17 '22 at 05:12
  • I keep seeing `bt-obex: obex service is not found Did you forget to run obexd?` when running `bt-obex` commands. I tried starting it with `systemctl --user` but then it complains that it's already running! – matth Jun 28 '23 at 01:49

This works on my computer:

bluedevil-sendfile -u /org/bluez/hci0/dev_<address with underscores instead of colons> -f <file_with_absolute_path>

For example:

bluedevil-sendfile -u /org/bluez/hci0/dev_00_FF_00_FF_00_FF -f /home/tux/test.pdf
