My computer (Lenovo, Intel dual core, 64 bit, 1.9 GB Mmemory) did not come with a bluetooth card installed. So I spent the $3 and bought a bluetooth USB connector. I plugged it in to my Ubuntu 14.04 machine and I was able to share the internet connection with my phone.

However, I was not able to share files between my phone and computer even after configuring the Personal File Sharing.

I figured it might be a driver problem so, installed

sudo apt-get install bluez bluez-alsa bluez-audio bluez-btsco bluez-compat bluez-cups bluez-dbg bluez-gstreamer bluez-hcidump bluez-pcmcia-support bluez-tools bluez-utils python-bluez bluewho indicator-bluetooth libbluetooth-dev  libgnome-bluetooth11 libbluetooth3

This installed blueman. Blueman changed the PAN settings from Network Manager to Blueman (dhclient) by default. Under Transfer Settings > Object Push I selected Enabled & Accept files from trusted devices and for Transfer Settings > File Sharing FTP I selected Enabled & Allow devices to write/delete.

STATUS QUO:

Now when I try to share the internet connection between my phone, it connects for several seconds then disconnects. Under the internet connections listings I literally see 3 duplicates of my phone network listed, where I previously saw only one.

When I select "Browse Files on Device" I get an error stating

Failed to launch default file browser..... The specified location is not mounted .... You can enter an alternate browser in service settings

When I select Send Files to Device via Bluetooth Manager I get

Error Occurred
Method "CreateSession" with signature "va{sv}" on interface org.bluez.obex.Client1" doesn't exist

When I select Send Files via the Ubuntu Bluetooth panel indicator I get this error:

GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.openobex.client was not provided by any .service files

FYI on my phone I am using Android 4.4.4 kikat Bluetooth File Transfer app. My phone connects to the computer, quite stably.

Here's the "curveball", I CAN send files from my phone to my computer. The files land in my downloads folder as set by Personal File Sharing. I created a separate folder called Bluetooth Transfers after installing Blueman. Files never go there.

CORRECTION: can't send files from my phone to the computer any longer. "object push" not found.

I think that the blueman drivers are not playing nicely with dbus, but I don't know how to fix it.

Any ideas?

When in doubt, purge it out... to solve the problem above I did the following:

sudo apt-get remove --purge bluez bluez-alsa bluez-audio bluez-btsco
bluez-compat bluez-cups bluez-dbg bluez-gstreamer bluez-hcidump
bluez-pcmcia-support bluez-tools bluez-utils python-bluez bluewho
indicator-bluetooth libbluetooth-dev  libgnome-bluetooth11
libbluetooth3

sudo apt-get remove --purge blueman

sudo reboot

sudo apt-get install bluez bluez-alsa bluez-audio bluez-btsco
bluez-compat bluez-cups bluez-dbg bluez-gstreamer bluez-hcidump
bluez-pcmcia-support bluez-tools bluez-utils python-bluez bluewho
indicator-bluetooth libbluetooth-dev  libgnome-bluetooth11
libbluetooth3

sudo reboot

sudo apt-get install network-manager network-manager-openvpn

sudo start network-manager

sudo apt-get install network-manager-gnome

sudo reboot

sudo apt-get install gnome-user-share

I believe that blueman had a bug causing the issue. So without blueman at all I can send and receive files between my phone and computer and share my phone wifi connection (it's stronger than my netcard).
