[Bug 1500242] Re: Bluetooth devices (Jabra BT250, Audi A3 car kit) can not be connected with BQ Aquaris 4.5

 

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 version: 191
version ubuntu: 20151130

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.

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?
