Bluetooth woes (again)

Patrick O'Callaghan
Once again my BT mouse is acting up and I have no idea why. I've been
using it with no problems for months, through successive updates to the
kernel, and it has Just Worked. Then suddenly it doesn't. The
configuration dialogues (on both Gnome and KDE) see the mouse and give
its Mac address, show it as paired, trusted and not blocked, but say
it's "unreachable". The mouse has adequate battery and power cycling
makes no difference.

My BT adaptor is a Broadcom dongle. It has up to date firmware (as of a
couple of months ago).

This has happened several times in the past (e.g. see
https://lists.fedoraproject.org/pipermail/users/2014-March/447579.html)
and just as suddenly seems to fix itself, sometimes after several days
of complete frustration.

This is F22 fully updated, using both kernel-4.1.8-200.fc22.x86_64 and
 kernel-4.2.3-200.fc22.x86_64

The mouse has never failed on my other system, a laptop running Fedora
21 but with a builtin BT adaptor.

If anyone has something to suggest, I'm all ears.

Had a similar problem. I changed the batteries with brand new one (Super
Alkaline) and it worked.

New battery made no difference.

The mouse is already paired. Furthermore, IIRC it has never asked me
for a key.

Have you by any chance or even by mistake changed the password?

To repeat: there is no password. This is a mouse. Not all BT devices
use keys and I have never been asked for a password (key) for this
device. I've even unconfigured the device and re-installed it. It still
didn't ask for a key. I've also (separately) removed and re-inserted
the dongle. On insertion I get this in dmesg:

[15213.164076] usb 3-1.2: Product: BCM20702A0
[15213.164079] usb 3-1.2: Manufacturer: Broadcom Corp

[15213.173312] Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0a5c-21e8.hcd not found

i.e. there's a problem loading the firmware. This happened in the past
and then stopped, but is now happening again. Googling for the error
message led me to instructions for updating the firmware, all of which
I followed last time this happened.

I've reported it to Bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1275122

BTW, this is the dongle: http://plugable.com/products/usb-bt4le#drivers

I had this problem with gnome. What I did, is to go to the bluetooth
device manager, delete the device, and then re-pair it again. This seems
to happen once when my battery in the mouse died.

Could try the old remote control repair trick - grind the battery around
on the battery terminal, scrape off any oxidisation.  If it's not the
type that can be rotated, then a minor polish of the metal on the
battery and terminals using something else may help.

In reality, some people should stick to running Windows and others

In the past when I had problems connecting to a device that "used to
work" I would deleted it from BT's list of known devices.

However, recently I discovered that "deleting" and "unpairing" are
distinct operations.  I could not move a kbd to a different system
by deleting it from the first, I had to unpair the kbd before it
would pair with the new system.

As I said, the mouse works on another system. I should also mention
that the mouse light is on, i.e. it does have power.

I'm leaning towards thinking the problem isn't with the mouse but with
the dongle (if in fact it's a hardware issue at all).

Probably. I did a search for BT problems before reporting it but must
have missed that one.

How do you unpair it? There is no such option in the settings dialogue
in KDE, nor in Gnome. There is an option for removing it, which I've
already tried.

One other thing I stumbled upon suggested a race condition of some sort.

You may want to try....

1.  Unplug dongle
2.  rmmod bluetooth
3.  plugin dongle

Most blue tooth mouse has a button to enable connection to a blue tooth
device. Generally, you need to push the button , typically underneath
the mouse and force the mouse to start the pairing action.

I've done that more times than I can count. Makes no difference.
Likewise turning the mouse off and on again, replacing the battery etc.

BTW the dongle *does* pair with my BT headphones. Go figure.

$ sudo rmmod bluetooth      
rmmod: ERROR: Module bluetooth is in use by: bnep btbcm btrtl btusb rfcomm btintel

I should mention that I have another wireless mouse/keyboard combo
(Microsoft) with its own USB dongle. This is self-contained, requires
no configuration and Just Works. It doesn't show up in the BT settings
dialogues but it may be what's preventing the rmmod from working.

I found an old dongle lying around and tried it. It works. The
conclusion seems obvious (though not clear).

Thanks to everyone who tried to help. I don't think it's worth pursuing
this any further. I just wonder why my logs show repeated problems
loading the driver (going back months) but nevertheless the old dongle
seemed to work until now.
