# Use case

Ubuntu 17.04, quite fresh installation, updated.

Bluetooth file transmission

I want to send files to my smartphone, and receive files sent by my
smartphone via bluetooth. I pair both devices, initiate file transfer
from one of the devices, and the other device asks me what to do.

# Problems

This is a mix from usability and technical issues.

1. OBEX disabled

The bluetooth file transmission service OBEX was not started. I started and 
enabled OBEX:
`systemctl --user start obex`
`systemctl --user enable obex`

```
Mai 30 14:47:55 tp systemd[1661]: Starting Bluetooth OBEX service...
Mai 30 14:47:55 tp obexd[8168]: OBEX daemon 5.43
```

2. OBEX silently fails

After having OBEX enabled, I was able to transmit files from laptop to
smartphone, yet I could not receive files on the laptop. In the system
log, you could see that OBEX fails (please note `FORBIDDEN`):

```
Mai 30 14:47:55 tp obexd[8168]: OBEX daemon 5.43
Mai 30 14:48:04 tp obexd[8168]: CONNECT(0x0), (null)(0xffffffff)
Mai 30 14:48:04 tp obexd[8168]: CONNECT(0x0), (null)(0x0)
Mai 30 14:48:04 tp obexd[8168]: PUT(0x2), (null)(0xffffffff)
Mai 30 14:48:04 tp obexd[8168]: PUT(0x2), FORBIDDEN(0x43)
Mai 30 14:48:04 tp obexd[8168]: DISCONNECT(0x1), (null)(0xffffffff)
Mai 30 14:48:04 tp obexd[8168]: DISCONNECT(0x1), SUCCESS(0x20)
Mai 30 14:48:04 tp obexd[8168]: disconnected: Transport got disconnected
```

I did not receive a popup notification asking me to receive the file or
not.

In the file sharing preferences `gnome-file-share-properties`, there is
a setting to automatically receive files via bluetooth. With this box
checked, you're finally able to receive files from your smartphone.

Successful log for comparison:
```
Mai 30 14:55:50 tp obexd[8168]: CONNECT(0x0), (null)(0xffffffff)
Mai 30 14:55:50 tp obexd[8168]: CONNECT(0x0), (null)(0x0)
Mai 30 14:55:50 tp obexd[8168]: PUT(0x2), (null)(0xffffffff)
Mai 30 14:55:50 tp obexd[8168]: PUT(0x2), CONTINUE(0x10)
Mai 30 14:56:28 tp obexd[8168]: DISCONNECT(0x1), (null)(0xffffffff)
Mai 30 14:56:28 tp obexd[8168]: DISCONNECT(0x1), SUCCESS(0x20)
Mai 30 14:56:28 tp obexd[8168]: disconnected: Transport got disconnected
```

# Expected behaviour

OBEX is started by default to handle bluetooth file transfers.

If no automatic file receipt is configured, a popup notification asks me
if I want to receive the file or not.

If this is not possible, there should be a notification pointing the
user to the configuration.
