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 90:03:B7:46:8E:E9 SEAT_BT
Device 00:80:00:00:15:76 Bluetooth Mouse

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

The I pressed “connect” in the screen of the Jabra of the phone:

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) ...

[CHG] Device 00:07:A4:00:A7:05 Connected: no

… 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.
