Re: Bluetooth woes (again)

One thing i have seen a few times with wireless keyboards/mice is that if you 
have both as wireless the placement of the dongle can become important. Try 
placing the dongle where you minimize interference between the devices. This 
usually affects the keyboard when the mouse is directly between the keyboard 
and the dongle or vice versa.

Still got a collection.  We have a few A1200s that still get used for
live titling (ScalaMM) on standard-def multicamera productions.  Some
A500s that I don't know what to do with (they can do the same thing, but
are slower and more painful at it, but dead silent with no HDD).  Ten
years worth of magazines and coverdiscs that I really need to let go.

I have to disagree, at least with this Logitech combo (I think it's

hours a day and I've had very few issues other than the occasional
battery death at inopportune times. The desk change requiring the dongle

plugged into the computer, and you have a cordless mouse that rides on
top of it (a bit like a Wacom tablet, but using a mouse instead of a
pen).  You get a cable free mouse, but don't need batteries, nor have to
deal with wireless issues.  The mouse pad is about as static on the desk
as a keyboard, so you don't have to deal with shifting cables getting
caught on things.


Yes, I don't know I'd ever use a corded mouse again if I'm given the
choice. The only gotcha is losing the dongle if you move around a bit.

That's the only reason I got them. They were really cheap on Amazon and
I'm very happy with them (rechargeable battery lasts about 10 hours). I
only mentioned them as an example of another BT device that does work

I had a wireless keyboard for a while, but it annoyed me for similar

it plugged in, and unplug it for those times that you wanted to take the

any problems of that sort, though I don't really like the layout and it
doesn't have backlit keys (which of course would eat battery power). As
it is, I've had it over a year in daily use and IIRC have not had to
change the battery yet.

Other than a new desk with enough metal in it to cause issues with the
signal at one time (fixed by relocating the dongle which is attached
via a USB cable), they've worked very well.

This is not an endorsement, just an observation. :-)

The light is continuous and has never flickered. In fact it stays on even

Yes, but I find them very awkward to use.  Perhaps a huge handball that
you can palm (like the old missile command arcade game) would get around
the main awkwardness.  But the main thing is that I find multiple
selection of items with anything other than a mouse very difficult.

e.g. Hold down shift and click on the first and last things you want to
select, or hold down control and select any random things you want to.

It's an awful of of spider-like finger twiddling to do such things, or
accurate and rapid darting about the screen, with a trackball.

The mouse is just acceptable for a bit of on-screen painting, such as
polishing up some photos, the trackball is awful.  For any large amount
of on-screen drawing, I have a humungous Wacom drawing table (tablet is
an understatement), the drawing area is bigger than A3.

As un-ergonomic as it is, the mouse is the least worst general purpose
pointing device.

That was one of my issues.  They don't seem designed for heavy use, just

I would guess an intermittent fault that grew into becoming permanent.
Most likely component failure, or the soldering.

Now you've got a working replacement, you could try being brutal to the
bad one.  Bang it a few times, hard, see if the thing suddenly starts
working again.  You often see that with soldering faults.  And you know
the device deserves it for messing you about.  ;-)

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.

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).

If you have a USB dongle, then the devices using that dongle are not
Bluetooth devices as far as your system is concerned, they are USB devices,
so they would not need or use the system's Bluetooth driver. The Bluetooth
driver is only needed if your system has a hardware Bluetooth device in it
and you are using that to connect your peripherals.

Definitely not. The speaker system has a port but it's not connected.
The headphones don't even have a physical port. BT is *only* way I ever
use these devices.

Maybe those devices can work with or without the dongle? Or maybe these
devices are somehow different than the devices I have experience with, that
used Bluetooth to communicate with the dongle, but didn't require any
Bluetooth software on the system, they showed up as USB devices.

Then why do my BT devices (mouse, headphones, an external speaker
system) show up under the BT settings dialogue? OTOH the separate
wireless mouse/kb dongle I mentioned *is* a USB device as far as the
system is concerned, but that's another matter.

If you have a USB dongle, then the devices using that dongle are not
Bluetooth devices as far as your system is concerned, they are USB
devices, so they would not need or use the system's Bluetooth driver.


Uhm, not quite 100% true. Odds are it will use the btusb driver, which 
in turn depends on bluetooth, btrtl, btintel and btbcm which will, in

their turn, load up various firmware files and such.


The Bluetooth driver is only needed if your system has a hardware
Bluetooth device in it and you are using that to connect your peripherals.


Not necessarily. Many laptops have the bluetooth built in, but it is
internally tied to the USB system (visible in a "lsusb -v").

In fact, come to think of it, I don't know that I've ever seen a
built-in bluetooth connected to the PCI bus. But that's just me. I'm not
saying it's never been done, but I've not seen it.

Those sorts of devices often have full-up driver stuff built into the
dongle, so the dongle itself does all the wireless stuff required
without bothering the system. Then, yes, they appear as USB devices
because that's all the dongle presents to the USB port. They're not
general-purpose BT dongles. My Logitech wireless keyboard/mouse does
precisely that. The wireless mouse shows up in "lsusb" as a USB-PS2
wireless mouse, but NOT as a BT mouse (because it isn't BT).

I have a Broadcom USB BT dongle. The BT dongle shows up in an "lsusb"
as a BT dongle.  Remember, Bluetooth means it uses RF in the correct
frequency bands and adheres to the Bluetooth protocols and that's all
it means.

Which is what my extra mouse/kb combo does, as I've said.

Mine too, and it shows up under lsusb. It has a BT MAC address which
appears under the settings dialogue, and it's also visible to hcitool
and hciconfig.  i.e. the system unquestionably knows that it's a BT
device. What it does with that information is another matter.

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'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.

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

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.

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.

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:

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:

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

Allegedly, on or about 25 October 2015, Patrick O'Callaghan sent:

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 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.

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.
