Modifications on the device (debugging information)
sudo mount -o remount,rw /
Since no bluetooth-override file was available I used:

sudo sed -i 's/exec \/usr\/sbin\/bluetoothd/exec \/usr\/sbin\/bluetoothd -d/g' /etc/init/bluetooth.conf
sudo sed -i 's/--start/--start --log-level=debug/g' /usr/share/upstart/sessions/pulseaudio.conf
I was not 100% sure about the ofono modifications: “Add '-d' to the exec line in /etc/init/ofono.override”. I have modified the line in ofono.override to:

exec ofonod -P -d provision,udev*,dun*,smart*,hfp_bluez5,stktest,sap

I tested this 2 times. 
1. I have restarted the phone after these modifications (logfile start with 1_*).
2. I have not restarted the phone and carried out the tests directly thereafter  (logfile start with 2_*). 


Issue with Jabra BT250 device
I followed the connection & pairing process with [bluetooth]# devices and made two screen shots:

[bluetooth]# devices

Device 00:80:00:00:15:76 Bluetooth Mouse

I put the Jabra is search mode and the phone found the device:

After this the Jabra changed from search mode into operational mode.
This is how the bluetooth window looked like after the pairing process
(correct symbol of the head set):


I can place calls and receive calls. I can end the calls with the button on the bluetooth device.
Then I turned the Jabra device off (power off of the device) ...

… and put it back on. I expect that the device automatically reconnects
to the phone. So first I did nothing just waiting.

I was alos not able to manually reconnect it.
The bluetooth window looked like the following (see the changed symbol!):

The window of the Jabra device looked like:


I have attached the debugging files:

/home/phablet/.cache/upstart/application-legacy-ubuntu-system-settings-.log 
/home/phablet/.cache/upstart/dbus.log

in version 1_* and 2_* as described above. Both habe been generated
during these session of the above steps. I hope this helps. If you need
anything further please let me know.

Title:
  Bluetooth devices (Jabra BT250, Audi A3 car kit) can not be connected
  with BQ Aquaris 4.5

Status in Canonical System Image:
  Confirmed
Status in bluez package in Ubuntu:
  Incomplete
Status in ofono package in Ubuntu:
  Incomplete

Bug description:
  STEPS:
  Requirements: Aquaris E4.5, Jabra BT250 blue tooth handset device (rather old one supports blue tooth 1.1 and therefore I thought should be no issue) or Audi car kit (A3 2012 model)

  1. Put Jabra BT250 into receiving mode
  2. Phone searches automatically every 15 - 30 seconds for a new blue tooth device
  3. Phone finds Jabra BT250 and asks for pairing code
  4. Enter code into phone
  5. Jabra BT250 automatically exits the pairing mode (which is a sign that pairing should have worked)
  6. Phone looses connection to Jabra BT250
  7. Manual reconnection via phone works (shows Jabra BT250 as being connected) but ignores the device

  Same behaviour with Audi car kit (Audi A3, 2012 model)

  EXPECTED:
  I expect that the blue tooth kits work similar to my Seat Alhambra (also 2012 model) where the blue tooth pairing etc. works great (except some bugs which are already filed).

  ACTUAL:
  No connection to the blue tooth device

  VERSIONS:
  OS-Build-Number: 25
  Ubuntu-Image: 20150825.1

  POSSIBLE ROOT CAUSE:
  Is this issue also solved as soon as bluez5 is implemented? When will this be?
