#193439 — Ubuntu 14.04 + bluetooth

FromKeith <me@privacy.net>
Date2016-10-30 10:55 +0000
SubjectUbuntu 14.04 + bluetooth
Message-ID<e7m1tgFrk1aU1@mid.individual.net>
Hi,

A while ago I was having problems getting wifi working on this HP 
17-y054sa laptop, which were all resolved per earlier thread.

My remaining challenge is to get Bluetooth working correctly.  It all 
_seems_ to work; I can turn Bluetooth on and off, I can make it visible 
and not.  But my phone cannot 'see' the laptop, and the laptop can't 
'see' the phone, even when both are flagged visible.  I know the phone 
is fine, because if I turn on Bluetooth when I'm in the pub, say, I 
immediately get a screenful of devices that are available to pair with.

I'm not a great tech, so I I'm hoping for some tips on how to diagnose 
what's going on!

Thanks,
K

My bad - just realised this is actually 16.04 not 14.04.

The only bad you made was installing Linux in the first place.
It's a common mistake but fortunately most people realize their
mistake and remove Linux just as quickly as they installed it.
For some people, like you for example, it takes longer to sink in.

Solving your problem requires a simple 2 step process.

Step 1 = Remove Linux completely.
Step 2 = Install Windows

Problem solved.

Well what is the chipset?

lspci | grep -i network

It's full of reassuring graphics.

https://wiki.ubuntu.com/Bluetooth

There is a command line.

bt-adapter
==========

- List available adapters
- Show information about adapter (incl properties)
- Discover remote devices (with remote device name resolving)
- Change adapter properties (eg. Name, Discoverable, Pairable, etc)

Nice toolset, but sadly the problem persists - can't see the phone, and 
the phone can't see the laptop.

Another possibility, is it's set up a Personal Area Network,
but this article makes it look like some proactive
steps must be taken. This is unlikely to happen by accident.

http://bluez.sourceforge.net/contrib/HOWTO-PAN

You could try ifconfig and see if
there is anything suspicious in there.

This would be on an "ordinary" networking
case, with only an Ethernet.

    ifconfig

    eth0
    lo

Whereas the PAN might add a bnep0 to it.

*******

Another possibility, is you have USB3 on the
computer, and the USB3 peripheral is "radiating"
a 2.4GHz signal. Intel wrote a paper on this,
complete with a spectrum analyzer scan, and
USB3 emits a broad signal with a peak at
maybe 2.5GHz or so. This could smother the
Bluetooth band and cover all the frequency
hopping bins, such that nothing gets through.

The USB2 on the other hand, "emits nothing".
At least, the spectral content would take
a high harmonic to hit any Wifi-like services.

USB3 has been known to interfere with
wireless keyboards too - you move the USB3
cable behind the computer so it's further
away from the keyboard area.

For a test, you could disconnect the USB3
peripheral, so nothing uses a blue USB3 port,
and retest for signal.

Since I have no Bluetooth here at all,
I can't simulate anything. I don't even
have a cellphone :-) Just VOIP.

I'm showing this:

And while there is a USB3 port on this machine, nothing is using it.

Stumped, I am!

Work your way through an Arch article.
They're pretty good for this sort of thing.
