[Bug 1694455] Re: Bluetooth: Cannot receive files, due to OBEX configuration

[Daniel van Vugt]

Per the description:

1. OBEX disabled

This part is bug 1645631, so please remove part #1 of the description
and just mention bug 1645631 instead.

2. OBEX silently fails

Let's make #2 the focus of this bug, so it is not seen as a duplicate of
bug 1645631

** Summary changed:

- Bluetooth: Cannot receive files, due to OBEX configuration
+ Bluetooth: Cannot receive files

** Description changed:

  # 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
+ 1. OBEX disabled (bug 1645631)
  
  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
+ 2. OBEX silently fails (this bug)
  
  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.
