Reporting on Bluetooth bug 1500242

I have send such a report on December, 6th 2015 where I have tested the
rc-proposed with my Jabra device. At that time the syslog-file was
missing which I have added later. I found out later, that syslog is a
rolling log, therefore maybe not all test logs are part of that syslog.

I have taken the time today to retest all that with the following
devices. I attach the log files:

Audi A3 car kit (2012 model)
Seat Alhambra car kit (2012 model)
Jabra BT250 head set
Logitech bluetooth mouse LogiLink ID0078 (Compatible to BT1.1/2.0/3.0+EDR)

Before testing I deleted all existing pairings with the devices and started from scratch.

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

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.

9:21 h turn off Jabra

9:22 h turn Jabra back on. I expect that the device automatically
reconnects to the phone. So first I did nothing just waiting.

There is a short period where the device is connected where I was able
to place the info command on it but shortly thereafter it was
disconnected.

I was also 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:




Logitec Bluetooth Mouse
This device worked once with the following rc version:

I did the test with the following rc-proposed version:
current build number: 191
device name: krillin
channel: ubuntu-
last update: 2015-11-30 17:03:26

version custom: 20151111-

Today I tried it again to complete the test and I got a different
behaviour:

9:27 h turn mouse on

no result – but it did work before with r191

try to remove Jabra & Audi profile from phone via the bluetooth phone
menue to see if this has an effect, but I am not able to remove the Audi
profile from the phone (the “delete profile” button is grayed out)

[DEL] Device 00:07:A4:00:A7:05 JABRA 250
[CHG] Device 00:0E:9F:E8:3A:24 Trusted: yes

now forced by console:

[DEL] Device 00:0E:9F:E8:3A:24 Audi UHV 4272           
Device has been removed

This caused a crash of the bluetooth application on the phone. I had to
completely stop the bluetooth device (via the bluetooth menue in the
phone (system settings) and restart bluetooth on the phone.
